Step 1
First, stand in front of the mirror and look at both of your breasts. You are looking for symmetry- in size, and shape of your breasts. Most women have one breast that is bigger than the other; this is normal. You are looking for something different, new or that you didn't notice before. Put both of your hands behind your head and spread your elbows out to the side. Examine your breasts. Note any dimpling (indentations in the skin), or obvious bumps.

Step 2
Lie down. One side at a time, put your arm above your head. With the other hand, begin at the outer part of your breast and use your fingertips to feel your breast. Move your fingertips in small circles and move around the perimeter of your breast. After you have made a complete circle, move in toward the nipple. Continue to do this until you have made it to the nipple. You will want to note any lumps or bumps. Do this on each side.

Step 3
Squeeze the nipple. Note any discharge. Do this on each side.

Step 4
Put your arm down at your side. Press around in your armpit. You are feeling for any lumps and bumps. Do this on each side.
