The American Cancer Society recommends monthly self-exams for women 20 and older.
Breast cancer is the second most deadly cancer for women.
When the disease is found and treated in the early stages, odds of survival are greatly increased. The best time to examine your breasts is about a week after your period begins, or if you've reached menopause, choose the same time to do it each month. You're looking for any unusual lumps, dimpling, or thickening in the breasts, as well as discharge from the nipple or any other abnormalities. Start by looking at your breasts in front of a mirror, first with your arms at your sides, then raised over your head, and finally, with hands pressed on your hips, flexing your chest muscles. Next, examine your breasts in the shower, keeping your fingers flat and moving them over each breast.
