Breast cancer awareness among women of reproductive age- a questionnaire based study.

INTRODUCTION: Breast cancer is the most frequent cancer in women worldwide, and its prevalence is rising among younger women of reproductive age. The study aims to investigate their awareness of breast cancer risk factors, warning indicators, and preventive methods. The study also aimed to assess participants' knowledge of breast self-examination (BSE) and their practices with this crucial screening method. METHODOLOGY: To achieve these goals, we used a cross-sectional survey employing a structured questionnaire. The questionnaire included multiple-choice and open-ended items about breast cancer awareness, knowledge, and practices. RESULTS: There were 400 questionnaires given out to female patients attending the out-patient department, and 290 of them were completed and returned. The majority of responders to our poll, 88 %, were aware that breast cancer is the most frequent cancer in women. The fact that 57 % of the individuals never examined their own breasts is a worrying result. There was a statistically significant difference between knowledge and family history (X2 = 13.8, P < 0.001) and knowledge and schooling (X2 = 6.4,P < 0.001). Both the practise of BSE and knowledge of BC were good in respondents under the age of 45, however they differed statistically significantly (X2-2.8,P = 0.041 and X2-2.6, P = 0.001, respectively). CONCLUSION: Understanding the extent of breast cancer awareness and knowledge gaps in this population is critical for planning targeted interventions and educational efforts. By identifying areas where knowledge is weak, healthcare practitioners and governments can implement policies to encourage early detection practices, reduce delays in seeking medical aid, and ultimately improve breast cancer outcomes.

Single nucleotide polymorphism of fatty acid desaturase gene and breast cancer risk in estrogen receptor subtype.

BACKGROUND: Breast cancer (BC) is the most common cancer of women and the second most common cancer overall globally. Data suggest that the plasma concentration of omega fatty acids (n-3 and n-6) and the impact of the genetic variant are associated with diet-related inflammatory disease, BC. This study was aimed to find an association between genetic variant rs174537 of fatty acid desaturase gene 1(FADS 1) and breast cancer estrogen receptor subtype. METHODOLOGY: Hundred and two blood samples from women were quantified for fatty acids by gas chromatography. SNP rs 174537(G > T) showed maximum variability and the strongest genetic determinant in the Genome-wide association study were genotyped using Sanger sequencing. RESULTS: The highest tertile of ALA showed a significantly reduced risk of BC compared to the lowest tertile (OR = 0.2, 95 %CL = 0.1-1.14, P = 0.03). Median values of ALA were higher in GT/TT genotype in ER +ve molecular subtype (P = 0.03) and DPA was higher in GG genotype of ER-ve molecular subtype (P = 0.037). When both the groups were put together the highest tertile of GG tertile showed significantly reduced risk of BC compared with the other lowest tertiles of GG and GT/TT genotypes (OR, 95% CL = 0.45(0.2-0.9). CONCLUSION: The high levels of arachidonic acid and low levels of n-3 fatty acids result in a pro-inflammatory milieu and that these pro-inflammatory effects might contribute to BC. We conclude that the individuals with genetically determined lower activity of FADS1(minor allele T) will derive greater advantage from n-3 FAs than those with higher FADS1 activity (G allele) and reduce the BC risk.

Alpha1-antitrypsin combined fatty acids induced angiopoietin-like protein 4, expression in breast cancer: A pilot study.

INTRODUCTION: The effect of nutrition on inflammation and breast cancer (BC) prognosis is still inconclusive. Mechanism of data suggests that different types of fatty acids (FAs) play an essential role in carcinogenesis, and binding of alpha 1 antitrypsin (A1AT) may modulate carcinogenesis. The increased expression in the bound form of A1AT and release of Angiopoietin-like protein 4 (Angptl4) targets the gene of peroxisome proliferator-activated receptor-gamma (PPAR-γ). Our aim of the study was to compare the effect of FA-free (A1AT-0) and FAs bound forms of A1AT on levels of IL-1ß, PPAR-gamma, and Angplt4 in breast cancer and control women. METHODOLOGY: 10 women with breast cancer and ten control women within the age group 25-60 years with normal (Pi) M allele A1AT were recruited. Mononuclear cells were isolated and treated with different A1AT and FAs on the various combinations (linoleic acid, alpha-linolenic acid) for time-dependent study (2,4,18 and 24 h) and analyzed for the interleukin -1 beta(IL-1b), PPAR-gamma, and Angiopoietin-like protein 4 (Angptl4) expression by using ELISA method and gas chromatography for analyzing FAs. One-way ANOVA combined with multiple comparisons is used to compare the means. RESULTS: 100% of the study subjects were homozygous for the normal allele of A1AT. Time-dependent effects of A1AT and A1AT conjugated fatty acids on IL-I b, PPAR-g and Angptl4 showed statistically significant P = 0.07, P = 0.001, and P = 0.02 respectively, compared to those of the former study subjects. But within the groups, PPAR-g levels in case group (F(15,40)1.606, P = 0.003) and Angptl4 in the control group (F(15,32)0.64, P = 0.043) differed significantly. CONCLUSION: To the best of our knowledge, it's the first kind of study, and we speculate that the A1AT complex with different types of FAs results in a new form of A1AT having a solid capability to regulate the inflammation-induced synthesis, processing, and release of an active form of IL-1ß. Our experimental data shows that the anti-inflammatory property of A1AT combined FAs likely to be mediated PPAR γand Angptl4 activation, thereby inhibiting the IL-1b. These findings may be worth assessing BC's biological effects and therapeutic effectiveness.

Plasma fatty acids composition and estimated delta desaturases activity in women with breast cancer.

INTRODUCTION: Fatty acids (FAs) are the vital constituents of membrane structures. De novo synthesis of FAs includes an enzymatic complex of FA synthase and delta desaturases. These enzymes are overexpressed in tumors, and inhibition of these enzymes is gaining interest. Our aim was to determine if delta desaturase activities are altered in breast cancer (BC) cases and if altered whether delta desaturase activities differ among BC genotypes. MATERIALS AND METHODS: In this observational comparative study, 50 women with BC and 30 control women were recruited for the study. Gas chromatography-flame ionization detector was used to measure the plasma FA levels. Desaturase activities were assessed as product-to-precursor FA ratios. The Wilcoxon signed-rank test was used to compare between two groups, and P ≤ 0.05 was considered as statistically significant. RESULTS: The FA analysis revealed higher levels of monounsaturated FAs (MUFAs) and linolenic acid metabolites (C18:3n-6, C20:4n-6) in BC patients, whereas C20:5n-3 was higher in controls. The Delta 9 desaturase (D9D) and D6D were higher in BC cases suggesting greater conversion saturated FA to MUFA and linoleic acid to its metabolites. D9D-16 activity was statistically significant (P = 0.03) in BC women, particularly in estrogen-receptor-positive patients. CONCLUSION: There is limited evidence to substantiate the link between diet and cancer. The current study showed there is an altered lipid desaturase activity. Nutritional intervention and drugs that target the FA pathway may provide a new approach to prevent and treat BC.

Maternal Occupational Tobacco Exposure and Newborn Umbilical Cord Serum Leptin Concentration.

OBJECTIVE: To assess the effect of maternal occupational tobacco handling (bidi rolling) on cord serum leptin levels. METHODS: We enrolled 64 neonates born to women who were bidi-rollers, and 64 small for gestational age (SGA) neonates and 57 term appropriate for gestational age (AGA) neonates born to mothers with no tobacco exposure. Cord blood leptin levels between the groups were compared. Adjusted mean difference in leptin was calculated using regression model. RESULTS: Cord leptin showed moderate correlation with birthweight (r=0.16; P=0.027) across the groups. Mean (SD) cord serum leptin levels (ng/mL) of study group was 19.79 (13.32), in comparison to 21.4 (13.4) of SGA (P=0.497), and 27.70 (13.96) of term AGA (P=0.002). Maternal occupational tobacco exposure contributed to significant decrease in cord leptin (adjusted mean difference (95%CI): -4.5 ng/mL (-8.82, -0.19); P=0.041). CONCLUSIONS: Maternal occupational tobacco exposure causes signifi-cant reduction in fetal leptin levels.
