Background: To reduce morbidity and mortality from breast cancer, early diagnosis and treatment is of great importance. For that purpose women should have awareness about the disease and also should be able to apply knowledge for prevention of the disease. Objectives: The study was conducted in view of understanding knowledge and attitude of urban women and to know their behaviour regarding breast cancer screening. Materials and Methods: The study was community based, cross-sectional study conducted in a urban slum and non-slum area which is a ?eld practice area of a Medical college. Women above 30 years of age were taken. Breast cancer screening and awareness programme is undertaken by the Dept. of Community Medicine in the ?eld practice area since last two years. Results: More than 50% of the women were found to have correct knowledge, favourable attitude and positive behaviour. More than half of the women were doing CBE and SBE but not all were doing it regularly. It was seen that knowledge was signi?cantly associated with practice. Conclusion: The study highlights the need for increasing awareness by reinforcing health education. Use of IEC activities and involvement of key persons in the area will be helpful.
