1) Breast self-examination (BSE) involves visually inspecting and feeling the breasts to check for lumps, thickening, or other changes that could indicate breast cancer. It is recommended that women examine their breasts once a month after age 20.
2) BSE helps detect breast cancer early when it is most treatable. Three techniques - the clock pattern, wedge pattern, and sweeping pattern - are described to thoroughly check the breasts.
3) Abnormal findings that should be reported to a doctor include lumps, skin changes, nipple discharge, or changes in breast size or shape. Regular BSE can improve early detection of breast cancer.
