Breast self-examination involves regularly examining one's own breasts to detect any lumps or changes. It is recommended that all women over 20 perform monthly breast self-exams. Early detection of breast cancer through self-exams and regular clinical exams can help cure 70-80% of cases. While self-exams do not reduce mortality, they can increase rates of further testing like mammography to evaluate any abnormalities found. The steps of breast self-examination include inspection of the breasts and underarms followed by palpation or feeling different areas of the breasts with fingers.
