INTRODUCTIONIt is estimated that the prevalence of breast cancer in India is 92.6/lakh population with a mortality rate of 12.7/lakh population.1 Breast Cancer though on the rise in Indian women, is still not perceived by the women as a disease that they are at risk. Women feel that they are unlikely to get breast cancer. Awareness about the disease, its risk factors and the need to undergo breast cancer screening is poor.Though both men and women can develop breast cancer, women are more at risk of breast cancer.2 Age increases the risk of breast cancer. Most breast cancers develop after the age of 50 years. 2 However in women, the age at which women get breast cancer is much lower than in developed countries, almost a decade earlier.3-5 Early onset of menarche, first live birth at the age of 30 years and above, never giving birth to a child, starting menopause after the age of 55 years, being physical inactive, being obese, having dense breasts, use of combined oral contraceptive pills, personal history of breast cancer, personal history of non-cancerous breast disease, previous radiotherapy treatment, and history of breast cancer in the first degree relatives increases the risk of breast cancer.

ABSTRACTBackground: Even though there is an increasing trend of breast cancer, women still do not perceive themselves at risk. Poor awareness about the disease and its risk factors and the absence of population based screening contribute to delayed diagnosis. The objective of the study was to assess the prevalence of various risk factors for breast cancer in women aged 30 years and above. Methods: The cross-sectional study using convenience sampling of all women aged 30 years and above was conducted in Mumbai. Of the 2430 women enumerated in the study area, 1158 women participated in the study. Risk factors for breast cancer assessed included age at menarche; age at first child birth; breastfeeding; use of oral contraceptive pills, age of menopause, first degree relatives with history of breast cancer, history of current and past breast cancer; history of any previous breast related abnormalities. Results: 15.5% of the women had atleast one risk factor for breast cancer. The prevalence of individual risk factors was below 6%. Conclusions: Prevalence of the risk factors for breast cancer is not very high, but never the less, the increasing trend of breast cancer in the country makes it imperative to introduce population based screening for all women with or without risk factor.
