Breast cancer is cancer that forms in the cells of the breasts.It is the most common type of cancer in Kenyan women.Breast cancer can also affect men but that is on very rare occassion.Promotion of breast awareness and education of women on breast health are important aspects in early detection of breast cancer. Mammography is the recommended mode of screening; breast magnetic resonance imaging (MRI) may be used in selected highrisk populations. Breast Self-Examination (BSE), clinical breast examination (CBE) and ultrasound are not screening modalities but are complementary to mammography and aid in early diagnosis of breast cancer. Age of starting screening as well as frequency will depend on risk assessment and stratification.
