Breast self-examination.

Abstract

A review of publications on breast self-examination (BSE) up to the middle of 1991 showed that evidence supporting BSE has strengthened since 1989. BSE is associated with a smaller size of tumor at diagnosis and has the potential to reduce breast cancer mortality. Mortality reduction is likely to be achieved only if BSE is competently performed and if appropriate diagnostic follow-up is accessible. Because screening is justified when preclinical disease is prevalent, BSE practice is important for women 40 years of age and older.
