Vital Signs: Mammography Use and Association with Social Determinants of Health and Health-Related Social Needs Among Women - United States, 2022.

Introduction: Approximately 40,000 U.S. women die from breast cancer each year. Mammography is recommended to screen for breast cancer and reduce breast cancer mortality. Adverse social determinants of heath (SDOH) and health-related social needs (HRSNs) (e.g., lack of transportation and social isolation) can be barriers to getting mammograms. Methods: Data from the 2022 Behavioral Risk Factor Surveillance System were analyzed to estimate the prevalence of mammography use within the previous 2 years among women aged 40-74 years by jurisdiction, age group, and sociodemographic factors. The association between mammography use and measures of SDOH and HRSNs was assessed for jurisdictions that administered the Social Determinants and Health Equity module. Results: Among women aged 50-74 years, state-level mammography use ranged from 64.0% to 85.5%. Having health insurance and a personal health care provider were associated with having had a mammogram within the previous 2 years. Among women aged 50-74 years, mammography prevalence was 83.2% for those with no adverse SDOH and HRSNs and 65.7% for those with three or more adverse SDOH and HRSNs. Life dissatisfaction, feeling socially isolated, experiencing lost or reduced hours of employment, receiving food stamps, lacking reliable transportation, and reporting cost as a barrier for access to care were all strongly associated with not having had a mammogram within the previous 2 years. Conclusions and Implications for Public Health Practice: Identifying specific adverse SDOH and HRSNs that women experience and coordinating activities among health care providers, social services, community organizations, and public health programs to provide services that help address these needs might increase mammography use and ultimately decrease breast cancer deaths.

Breast cancer screening motivation and behaviours of women aged over 75 years: a scoping review.

BACKGROUND: This scoping review aimed to identify and present the evidence describing key motivations for breast cancer screening among women aged ≥ 75 years. Few of the internationally available guidelines recommend continued biennial screening for this age group. Some suggest ongoing screening is unnecessary or should be determined on individual health status and life expectancy. Recent research has shown that despite recommendations regarding screening, older women continue to hold positive attitudes to breast screening and participate when the opportunity is available. METHODS: All original research articles that address motivation, intention and/or participation in screening for breast cancer among women aged ≥ 75 years were considered for inclusion. These included articles reporting on women who use public and private breast cancer screening services and those who do not use screening services (i.e., non-screeners). The Joanna Briggs Institute (JBI) methodology for scoping reviews was used to guide this review. A comprehensive search strategy was developed with the assistance of a specialist librarian to access selected databases including: the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Web of Science and PsychInfo. The review was restricted to original research studies published since 2009, available in English and focusing on high-income countries (as defined by the World Bank). Title and abstract screening, followed by an assessment of full-text studies against the inclusion criteria was completed by at least two reviewers. Data relating to key motivations, screening intention and behaviour were extracted, and a thematic analysis of study findings undertaken. RESULTS: A total of fourteen (14) studies were included in the review. Thematic analysis resulted in identification of three themes from included studies highlighting that decisions about screening were influenced by: knowledge of the benefits and harms of screening and their relationship to age; underlying attitudes to the importance of cancer screening in women's lives; and use of decision aids to improve knowledge and guide decision-making. CONCLUSION: The results of this review provide a comprehensive overview of current knowledge regarding the motivations and screening behaviour of older women about breast cancer screening which may inform policy development.

Breast Cancer Stage and Size Detected with Film versus Digital Mammography in New South Wales, Australia: A Population-Based Study Using Routinely Collected Data.

BACKGROUND: Digital mammography has replaced film mammography in breast-screening programs globally, including Australia. This led to an increase in the rate of detection, but whether there was increased detection of clinically important cancers is uncertain. METHODS: In this population-wide retrospective cohort study in New South Wales, Australia spanning 2004 to 2016 and including 4,631,656 screens, there were 22,965 cancers in women screened with film (n = 11,040) or digital mammography (n = 11,925). We examined the change in tumor characteristics overall and how these rates changed over time, accounting for changes in background rates using an interrupted time-series. Comparisons were made with unscreened women (n = 26,326) during this time. RESULTS: We found increased detection of in situ cancer (3.36 per 10,000 screens), localized invasive, and smaller-sized breast cancers attributable to the change in mammography technology, whereas screen-detected intermediate-sized and metastatic breast cancers decreased. Rates of early-stage and intermediate-sized interval cancers increased, and late-stage (-1.62 per 10,000 screens) and large interval cancers decreased. In unscreened women, there were small increases in the temporal trends of cancers across all stages. CONCLUSIONS: At least some of the increased detection of smaller early-stage cancers may have translated into a reduction in larger and late-stage cancers, indicating beneficial detection of cancers that would have otherwise progressed. However, the increased detection of smaller early-stage and small cancers may also have increased over-diagnosis of lesions that would otherwise have not caused harm. IMPACT: Robust evaluation of potential benefits and harms is needed after changes to screening programs. See related In the Spotlight, p. 638.

Analysis of Breast Cancer Screening Results and Influencing Factors of Breast Cancer in Guangdong Province from 2017 to 2021.

BACKGROUNDS: Breast cancer screening plays an important role in the early detection, diagnosis and treatment of breast cancer. The aim of this study was to evaluate the screening results and explore the influencing factors of breast cancer detection rate in Guangdong. METHODS: This cross-sectional study was conducted among 2,024,960 women aged 35-64 in Guangdong Province during 2017-2021. The data about breast cancer screening information were collected from the Guangdong maternal and child health information system. Descriptive statistical analysis was used to explain demographic characteristics and results of breast cancer screening. The generalized linear regression model was applied to analyze the related influencing factors of breast cancer detection rate. RESULTS: The estimated detection rate of breast cancer in Guangdong Province is 70.32/105, with an early diagnosis rate of 82.06%. After adjusting covariates, those women with older age (45-55 [OR (95% CI) 2.174 (1.872, 2.526)], 55-65 [OR (95% CI) 2.162 (1.760, 2.657)]), education for high school ([OR (95% CI) 1.491 (1.254, 1.773)]) and older age at first birth ([OR (95% CI) 1.632 (1.445, 1.844)]) were more likely to have higher detection rate of breast cancer. No history of surgery or biopsy ([OR (95% CI) 0.527 (0.387, 0.718)]), no history of breast cancer check ([OR (95% CI) 0.873 (0.774, 0.985)]) and no family history of breast cancer ([OR (95% CI) 0.255 (0.151, 0.432)]) women were more likely to screen negative for breast cancer (P < 0.05). CONCLUSION: The detection rate of breast cancer in screening showed an increasing trend year by year in Guangdong Province. Older age, education for high school and older age at first birth were risk factors for breast cancer detection rate, while no surgery or biopsy history, no family history of breast cancer and no history of breast cancer check were protective factors.

Understanding mechanisms of racial disparities in breast cancer: an assessment of screening and regular care in the Carolina Breast Cancer Study.

PURPOSE: Screening history influences stage at detection, but regular preventive care may also influence breast tumor diagnostic characteristics. Few studies have evaluated healthcare utilization (both screening and primary care) in racially diverse screening-eligible populations. METHODS: This analysis included 2,058 women age 45-74 (49% Black) from the Carolina Breast Cancer Study, a population-based cohort of women diagnosed with invasive breast cancer between 2008 and 2013. Screening history (threshold 0.5 mammograms per year) and pre-diagnostic healthcare utilization (i.e. regular care, based on responses to "During the past ten years, who did you usually see when you were sick or needed advice about your health?") were assessed as binary exposures. The relationship between healthcare utilization and tumor characteristics were evaluated overall and race-stratified. RESULTS: Among those lacking screening, Black participants had larger tumors (5 + cm) (frequency 19.6% vs 11.5%, relative frequency difference (RFD) = 8.1%, 95% CI 2.8-13.5), but race differences were attenuated among screening-adherent participants (10.2% vs 7.0%, RFD = 3.2%, 0.2-6.2). Similar trends were observed for tumor stage and mode of detection (mammogram vs lump). Among all participants, those lacking both screening and regular care had larger tumors (21% vs 8%, RR = 2.51, 1.76-3.56) and advanced (3B +) stage (19% vs 6%, RR = 3.15, 2.15-4.63) compared to the referent category (screening-adherent and regular care). Under-use of regular care and screening was more prevalent in socioeconomically disadvantaged areas of North Carolina. CONCLUSIONS: Access to regular care is an important safeguard for earlier detection. Our data suggest that health equity interventions should prioritize both primary care and screening.

Comparisons of assessment pathways after abnormal mammography screening in Denmark, Norway, and Spain.

PURPOSE: To ensure high-quality screening programmes and effective utilization of resources, it is important to monitor how cancer detection is affected by different strategies performed at recall assessment. This study aimed to describe procedures performed at recall assessment and compare and evaluate the performance of the assessment in Denmark, Norway, and Spain in terms of screen-detected cancer (SDC) and interval cancer (IC) rates. METHODS: We included women aged 50-69 years from Denmark, Norway, and Spain, who were recalled for assessment after screening mammography, and recorded all procedures performed during six months after diagnosis, and the timing of the procedures. Women were followed for two years and screen-detected and interval cancer, and sensitivity of recall was calculated and compared. RESULTS: In total, data from 24,645 Danish, 30,050 Norwegian, and 41,809 Spanish women were included in the study. Most of the women had some assessment within 2 months in all three countries. SDC rates were higher in Denmark (0.57) and Norway (0.60) compared to Spain (0.38), as were the IC rates, i.e. 0.25 and 0.18 vs. 0.12, respectively. The sensitivity of the diagnostic follow-up was somewhat higher in Denmark (98.3%) and Norway (98.2%), compared to Spain (95.4%), but when excluding non-invasive assessment pathways, the sensitivities were comparable. CONCLUSION: This comparison study showed variation in the assessment procedures used in the three countries as well as the SDC and IC rates and the sensitivity of recall.

Impact of changes to invite methodology on equality of access to the National Breast Screening Programme in the South of England.

In response to the COVID-19 pandemic, a temporary change in policy was implemented in 2020. Breast screening services in England were advised to change from timed appointments to an open invitation for invitees to contact the service and arrange an appointment. This change to invitation methodology had potential benefits and risks including impacting inequalities in uptake. Qualitative data were collected by online questionnaire from 23 service providers and routinely collected quantitative uptake data were analysed to investigate the impact of open invitations on the National Programme in the South of England. Office for National Statistics and general practitioner (GP) practice profile data enabled the modelling of sociodemographic characteristics of breast screening invitees at each GP practice. Most services changed to open invitations (17/23), 82% of which altered administrative capacity and/or procedures to accommodate this change. Logistic benefits were reported including a more consistent flow of participants, fewer long gaps and fewer wasted slots. The change to open invitations was associated with a 7.2% reduction in the percentage of participants screened, accounting for participant sociodemographics and historical screening provider uptake. The inequality in screening uptake experienced by participants of minority ethnic background was exacerbated by the change to open invitations. Open invitations, whilst affording logistic benefits in an unprecedented pandemic era, were associated with reduced overall uptake and exacerbation of existing health inequality experienced by women of minority ethnic background. The broader impact on services highlighted the need for sustainability of measures taken to accommodate such operational changes.

Racial disparities in the screening mammography continuum within a heterogeneous health care system.

BACKGROUND: Decreased mammography drives breast cancer disparities. Black women have lower rates of mammography completion than White women, and this contributes to disparities in outcomes. Points of disparity along the continuum for screening mammography remain underresearched. METHODS: The authors compared mammography referrals for Black and White women aged 40-74 years at a heterogeneous academic medical center. Completion of steps of the screening mammography continuum was compared between Black and White women within two age cohorts: 40-49 and 50-74 years. Multivariable logistic regression was used to evaluate the association between race and mammogram completion. RESULTS: Among 26,476 women, 3090 (12%) were Black, and 23,386 (88%) were White. Among Black women aged 50-74 years who were due for mammography, 40% had referrals, 39% were scheduled, and 21% completed mammography; the corresponding values for White women were 42%, 41%, and 27%, respectively. Similar differences in referral outcomes were noted for women aged 40-49 years, although Black women had lower rates of provider-initiated referrals (9% vs. 13%). Adjusted analyses for those aged 40-49 and 50-74 years demonstrated an association between Black race and lower rates of mammography completion (odds ratio [OR] for 40-49 years, 0.74; 95% CI, 0.57-0.95; p = .02; OR for 50-74 years, 0.85; 95% CI, 0.74-0.98; p = .02). In multivariable analyses, noncommercial insurance and higher comorbidity were associated with lower rates of mammography. Provider-initiated referral was positively correlated to mammogram completion. CONCLUSIONS: Black race was associated with 15%-26% lower mammography completion (adjusted). Both groups experienced the highest attrition after scheduling mammograms, although attrition was more precipitous for Black women. These findings have implications for future interventions, including increasing provider-initiated referrals and decreasing barriers to attending scheduled mammograms.

Women's Reactions to Breast Density Information Vary by Sociodemographic Characteristics.

BACKGROUND: Breast density information aims to increase awareness of breast density and its risks and to foster more informed future breast screening decisions among women with dense breasts. We explored associations between such information and outcomes including anxiety, confusion, or feeling informed, and whether they varied by race/ethnicity or literacy, or differentially affected future mammography plans. METHODS: A national telephone survey of a diverse sample of women previously informed of personal breast density (N = 1,322) assessed reactions to receipt of breast density information and future mammography plans. RESULTS: Most women (86%) felt informed after receiving personal breast density information; however, some felt anxious (15%) or confused (11%). Reactions varied significantly by sociodemographics; non-Hispanic Black, Asian, and Hispanic women and women with low literacy were nearly two to three times more likely to report anxiety than non-Hispanic White women (all ps < .05). Asian women and those with low literacy less often felt informed and more often felt confused. Non-Hispanic Black and Asian women were nearly twice as likely to report that knowing their breast density made them more likely to have future mammograms. Women with low literacy were more likely to change mammography plans, with some being more likely and others less likely to plan to have future mammograms. Greater anxiety and confusion were associated with higher likelihood of planning future mammograms; those feeling informed were less likely to plan future mammography. CONCLUSIONS: Differential reactions to breast density information are concerning if associated with disparate future screening plans. Future breast density education efforts should ensure that such information is readily accessible and understandable to all women in order to lead to desired effects.

Urbanicity, Income, and Mammography-Use Disparities Among American Indian Women.

INTRODUCTION: Reported breast cancer screening among American Indian women is consistently below that of White women. The last claims-based trends were from 1991 to 2001. This study updates mammography trends for American Indian women and examines the impact of race, urbanicity, and income on long-term mammography use. METHODS: This was a multi-year (2005-2019), retrospective study of women aged 40-89 years using a 5% sample of Medicare fee-for-service beneficiaries residing in Arizona, California, New Mexico, Oklahoma, and Washington. This study used multivariable logistic regression to examine the impact of urbanicity and income on receiving mammography for American Indian women compared with that for White women. Analyses were conducted in 2022. RESULTS: Overall, annual age-adjusted mammography use declined from 205 per 1,000 in 2005 to 165 per 1,000 in 2019. The slope of these declines was significantly steeper (difference = -2.41, p<0.001) for White women (-3.06) than for American Indian women (-0.65). Mammography-use odds across all urbanicity categories were less for American Indian women than for White women compared with those of their respective metropolitan counterparts (e.g., rural: 0.96, 95% CI=0.77, 1.20 for American Indian women and 1.47, 99% CI=1.39, 1.57 for White women). Although residing in higher-income communities was not associated with mammography use for American Indian women, it was 31% higher for White women (OR=1.31, 99% CI=1.28, 1.34). CONCLUSIONS: The disparity in annual age-adjusted mammography use between American Indian and White women narrowed between 2005 and 2019. However, the association of urbanicity and community income on mammography use differs substantially between American Indian and White women. Policies to reduce disparities need to consider these differences.

Cancer Screening after the Adoption of Paid-Sick-Leave Mandates.

BACKGROUND: By the end of 2022, nearly 20 million workers in the United States have gained paid-sick-leave coverage from mandates that require employers to provide benefits to qualified workers, including paid time off for the use of preventive services. Although the lack of paid-sick-leave coverage may hinder access to preventive care, current evidence is insufficient to draw meaningful conclusions about its relationship to cancer screening. METHODS: We examined the association between paid-sick-leave mandates and screening for breast and colorectal cancers by comparing changes in 12- and 24-month rates of colorectal-cancer screening and mammography between workers residing in metropolitan statistical areas (MSAs) that have been affected by paid-sick-leave mandates (exposed MSAs) and workers residing in unexposed MSAs. The comparisons were conducted with the use of administrative medical-claims data for approximately 2 million private-sector employees from 2012 through 2019. RESULTS: Paid-sick-leave mandates were present in 61 MSAs in our sample. Screening rates were similar in the exposed and unexposed MSAs before mandate adoption. In the adjusted analysis, cancer-screening rates were higher among workers residing in exposed MSAs than among those in unexposed MSAs by 1.31 percentage points (95% confidence interval [CI], 0.28 to 2.34) for 12-month colorectal cancer screening, 1.56 percentage points (95% CI, 0.33 to 2.79) for 24-month colorectal cancer screening, 1.22 percentage points (95% CI, -0.20 to 2.64) for 12-month mammography, and 2.07 percentage points (95% CI, 0.15 to 3.99) for 24-month mammography. CONCLUSIONS: In a sample of private-sector workers in the United States, cancer-screening rates were higher among those residing in MSAs exposed to paid-sick-leave mandates than among those residing in unexposed MSAs. Our results suggest that a lack of paid-sick-leave coverage presents a barrier to cancer screening. (Funded by the National Cancer Institute.).

Cost-effectiveness evaluation of risk-based breast cancer screening in Urban Hebei Province.

To evaluate the implementations of Cancer Screening Program in Urban Hebei and to model the cost-effectiveness of a risk-based breast Cancer Screening Program. Women aged 40-74 years were invited to participate the Cancer Screening Program in Urban Hebei form 2016 to 2020 by completing questionnaires to collect information about breast cancer exposure. Clinical screening including ultrasound and mammography examination were performed. We developed a Markov model to estimate the lifetime costs and benefits, in terms of quality-adjusted life years (QALY), of a high-risk breast Cancer Screening Program. Nine screening strategies and no screening were included in the study. The age-specific incidence, transition probability data and lifetime treatment costs were derived and adopted from other researches. Average cost-effectiveness ratios (ACERs) were estimated as the ratios of the additional costs of the screening strategies to the QLYG compared to no screening. Incremental cost-effectiveness ratios (ICERs) were calculated based on the comparison of a lower cost strategies to the next more expensive and effective strategies after excluding dominated strategies and extendedly dominated strategies. ICERs were used to compare with a willingness-to-pay (WTP) threshold. Sensitivity analysis was explored the influence factors. A total of 84,029 women completed a risk assessment questionnaire, from which 20,655 high-risk breast cancer females were evaluated, with a high-risk rate of 24.58%. There were 13,392 high-risk females completed the screening program, with participation rate was 64.84%. Undergoing ultrasound, mammography and combined screening, the suspicious positive detection rates were 15.00%, 9.20% and 19.30%, and the positive detection rates were 2.11%, 2.76% and 3.83%, respectively. According to the results by Markov model, at the end of 45 cycle, the early diagnosis rates were 55.53%, 60.68% and 62.47% underwent the annual screening by ultrasound, mammography and combined, the proportion of advanced cancer were 17.20%, 15.85% and 15.36%, respectively. Different screening method and interval yield varied. In the exploration of various scenarios, annual ultrasound screening is the most cost-effective strategy with the ICER of ¥116,176.15/QALY. Sensitivity analyses demonstrated that the results are robust. Although it was not cost effective, combined ultrasound and mammography screening was an effective strategy for higher positive detection rate of breast cancer. High-risk population-based breast cancer screening by ultrasound annually was the most cost-effective strategy in Urban Hebei Province.

Providing Free Mammography Screening to Uninsured Muslim Women in South Florida.

Despite studies indicating that Muslim women are less likely to meet recommended breast cancer screening guidelines, outreach specific to this population has been minimal. This article details a partnership between a mobile mammography center and a mosque, aimed at increasing mammography screening for uninsured Muslim women in South Florida.

Mammography Compliance for Arizona and New Mexico Hispanic and American Indian Women 2016-2018.

Hispanic and American Indian (AI) women experience lower breast cancer incidence than non-Hispanic White (NHW) women, but later-stage diagnoses and lower survival rates, suggesting issues with screening and healthcare access. Between 1999-2015, NHW breast cancer incidence decreased by 10% but increased by 8% for AI women. This study used 2016 and 2018 Behavioral Risk Factor Surveillance System data for Arizona and New Mexico to explore mammography screening. Analyses included Hispanic, AI, and NHW women aged ≥40 years (n = 12,830) to calculate age-specific compliance by race/ethnicity, logistic regression, and adjusted and sample-weighted evaluated associations between compliance and socio-economic covariates. In total, 75.1% of Hispanic women aged 50-74 reported mammography in the past two years (United States Preventive Services Task Force compliant) compared to 73.9% of NHW and 71.0% of AI women. Women who reported doctor visits in the past 12 months were likelier to comply than those without (AOR = 4.2 for Hispanic, 2.9 for AI, and 3.2 for NHW women). Reporting access to a personal doctor was related to compliance, except for AI women. While screening compliance was over 74%, visiting a healthcare provider in the past 12 months was essential. AI women reported issues that suggest unique challenges when deciding on mammography.

Diretriz brasileira para detecção precoce do câncer de mama: desafios para implantação / Brazilian breast cancer early detection guideline: challenges for implementation

Objetivo: Avaliar o acesso e a adesão da população feminina, atendida pelo Sistema Único de Saúde (SUS), à Diretriz Brasileira de Detecção Precoce do Câncer de Mama, em duas cidades de médio porte de uma região metropolitana do estado de São Paulo, Brasil. Métodos: Estudo transversal. Os dados foram coletados no Sistema de Informação do Câncer (Siscan) e nas Secretarias Municipais de Saúde no período de 01/01 a 31/12 de 2017. Resultados: Em Santa Bárbara d'Oeste, foram realizadas 3.106 mamografias: 2.931 (94,4%) BI-RADS® 1-2; 21 (0,7%) BI-RADS® 3; 12 (0,4%) BI-RADS® 4-5; 142 (4,5%) BI-RADS® 0. A maioria dos exames (1.855 ­ 59,7%) foi realizada em mulheres de 50 a 69 anos. A cobertura mamográfica na população de risco foi de 11,2%. O envelhecimento foi relacionado ao BI-RADS® 4-5 (p = 0,005). A idade jovem esteve relacionada ao maior número de BI-RADS® 0 (p = 0,03). Em Vinhedo, foram realizadas 1.996 mamografias: 1.835 (91,9%) BI-RADS® 1-2; 9 (0,45%) BI-RADS® 3; 7 (0,35%) BI-RADS® 4-5; 145 (7,3%) BI-RADS® 0. A maioria dos exames (975 ­ 48,8%) foi realizada em mulheres de 50-69 anos. A população coberta pela mamografia foi de 17%. Reunindo ambas as análises populacionais, evidenciou-se que o envelhecimento esteve relacionado ao maior número de casos suspeitos (p = 0,007). Conclusão: A maioria das mamografias foi realizada em mulheres de 50-69 anos. A cobertura mamográfica ficou aquém da encontrada no Brasil e recomendada pela Organização Mundial da Saúde.

Objective: To evaluate the access and adherence of the female population, assisted by Health Unic System (SUS), to Brazilian Breast Cancer Early Detection Guideline in two medium-sized cities of a metropolitan region in the State of São Paulo, Brazil. Methods: Cross-sectional study. Data were collected from the Cancer Information System (Siscan) and from the Municipal Health Secretariats between 01/01 to 12/31, 2017. Results: In Santa Bárbara d'Oeste 3,106 mammograms were performed: 2,931 (94.4%) BI-RADS® 1-2; 21 (0.7%) BI-RADS® 3; 12 (0.4%) BI-RADS® 4-5; 142 (4.5%) BI-RADS® 0. Most of the exams (1,855 ­ 59.7%) among women aged 50-69 years. The mammographic coverage at risk population was 11.2%. Aging was related to BI-RADS® 4-5 (p = 0.005). The young age was related to the highest number of BI-RADS® 0 (p = 0.03). In Vinhedo 1,996 mammograms were performed: 1,835 (91.9%) BI-RADS® 1-2; 9 (0.45%) BI-RADS® 3; 7 (0.35%) BI-RADS® 4-5; 145 (7.3%) BI-RADS® 0. Most of the exams (975 ­ 48.8%) among women aged 50-69 years. The population covered by mammography was 17%. Gathering both population analysis, it was shown that aging was related to the highest number of suspected cases (p = 0.007). Conclusion: Most mammograms were performed between 50-69 years. Mammographic coverage fell short of that found in Brazil and recommended by the World Health Organization.

Encuesta a mujeres uruguayas sobre conocimientos relacionados con la prevención del cáncer de mama / Survey of Uruguayan women on knowledge related to the prevention of breast cancer / Levantamento de mulheres uruguaias sobre conhecimentos relacionados à prevenção do câncer de mama

Introducción: En Uruguay el cáncer de mama (CM) ocupa el primer lugar en incidencia y mortalidad por cáncer en mujeres. Objetivo: Evaluar el conocimiento de mujeres uruguayas sobre el tamizaje de cáncer de mama. Material y métodos: Se trata de un estudio observacional descriptivo y transversal. Se aplicó una encuesta dirigida a mujeres, que fue difundida mediante las redes sociales. El consentimiento informado se solicitó al inicio de la encuesta, como requisito excluyente para poder realizar la misma. Se mantuvo el anonimato de las pacientes en el análisis estadístico y se contó con la aprobación del Comité de Ética del Hospital de Clínicas. Resultados: Participaron 1859 mujeres. El 75.1% (1396) de las encuestadas reconoce el CM como el de mayor mortalidad en mujeres. El 52% (967) cree que 3 de cada 10 mujeres tienen riesgo de desarrollar CM, y 18.4% (342) desconoce su prevalencia. El 60.2% (1119) reconoce a la mamografía como prueba que ha logrado disminuir la mortalidad por CM. El 64.2% (1193) cree que se realiza a partir de los 40 años. Sobre la frecuencia, el 60.5% (1125) considera que se realiza de forma anual. Los factores de riesgo para desarrollar CM mayormente considerados fueron tabaquismo (60.9%, 1132), obesidad (57.%, 1060) y sedentarismo (56.8%,1056). Conclusiones: Nuestros resultados evidencian que las encuestadas están informadas de manera adecuada sobre la importancia del CM y de realizar el tamizaje mamográfico para prevenirlo; sin embargo, el 74.3% (1381) cree que el mismo, debe comenzar a hacerse a los 40 años.

Introduction: In Uruguay, breast cancer (BC) has the highest incidence and mortality of all cancer in women. Objectives : To assess the knowledge of Uruguayan women about breast cancer screening for the early detection of BC. Material and Methods : This is a descriptive and observational study. A survey was applied to woman, it was disseminated through social networks. Informed consent was requested at the beginning of the survey as an exclusive requirement to be able to carry it out. In the statistical analysis, the anonymity of the patients was maintained and the approval of the Ethics Committee of the Hospital de Clínicas was obtained. Results : 1859 women participated. 75.1% (1396) of those surveyed recognize BC as the one with the highest mortality in women. 52% (967) believe that 3 out of 10 women are at risk of developing BC, and 18.4% (342) do not know its prevalence. 60.2% (1119) recognize mammography as a test that has managed to reduce mortality from BC. 64.2% (1193) believe that it is done after 40 years of age. Regarding the frequency, 60.5% (1125) consider that it is carried out annually. The most considered risk factors for developing BC were smoking (60.9%, 1132), obesity (57%, 1.060) and sedentary lifestyle (56.8%, 1056).

Introdução : No Uruguai, o câncer de mama (CM) tem a maior incidência e mortalidade de todos os cânceres em mulheres. Objetivos: Avaliar o conhecimento de mulheres uruguaias sobre o rastreamento do câncer de mama para a detecção precoce do CM. Material e Métodos : Trata-se de um estudo descritivo e observacional. Foi aplicado um questionário às mulheres, divulgado através das redes sociais. O consentimento informado foi solicitado no início da pesquisa como requisito exclusivo para poder realizá-la. Na análise estatística, foi mantido o anonimato dos pacientes e obtida a aprovação do Comitê de Ética do Hospital de Clínicas. Resultados: participaram 1859 mulheres. 75.1% (1396) dos pesquisados ​​reconhecem o CB como o de maior mortalidade em mulheres. 52% (967) acreditam que 3 em cada 10 mulheres estão em risco de desenvolver CM e 18.4% (342) não conhecem sua prevalência. 60.2% (1119) reconhecem a mamografia como um exame que tem conseguido reduzir a mortalidade por CM. 64.2% (1.193) acreditam que é feito após os 40 anos. Em relação à frequência, 60.5% (1125) consideram que é realizado anualmente. Os fatores de risco mais considerados para desenvolver CM foram tabagismo (60.9%, 1132), obesidade (57%, 1.060) e sedentarismo (56.8%, 1056). Conclusões: Nossos resultados mostram que as entrevistadas estão adequadamente informadas sobre a importância do MC e a realização da mamografia de rastreamento.
