RESUMEN
BACKGROUND AND PURPOSE: The global incidence of breast cancer is the highest among all cancers and is the primary reason for cancer-related fatalities. Our study aimed to assess the predictors of quality of life (QOL) and mental health in breast cancer survivors in Northern Iran. METHODS: This cross-sectional study was done on 96 female breast cancer survivors between the ages of 20 and 65 and was based on convenience samples. We gathered information through demographic and fertility data, a QOL survey, and the Hospital Anxiety and Depression Scale (HADS). A significance level of P < 0.05 was set for the analysis. RESULTS: In this study, results showed that 11.5% of women had the optimal quality of life, 31.3% favorable quality of life, and 57.3% undesirable quality of life. The average HADS score was 20.14 ± 3.07, with anxiety scores of 10.21 ± 2.31 and depression scores of 9.93 ± 1.64. On multiple linear regression, marital relationship and the number of children were predictors of quality of life (ß=-17.624, p = 0.023 and ß=-7.427, p = 0.016, respectively), as well as the husband's education and having no history of other cancers in the woman, were the most important predictors of HADS (ß = 0.763, p = 0.039 and ß=-0.528, p = 0.016, respectively). CONCLUSION: It is crucial to provide exceptional care to breast cancer patients during treatment and post-recovery. Emotional and psychological support is a fundamental requirement for their well-being.
