Give yourself a breast self-exam at least once a month. Look for any changes in breast tissue, such as changes in size, a lump, dimpling or puckering of the breast, or a discharge from the nipple. If you discover a persistent lump in your breast or any changes in breast tissue, it is very important that you see a physician immediately.
