As you do these steps, you should feel your chest muscles tighten. Watching closely in the mirror, clasp your hands behind your head and press your hands forward, looking for the changes described in step 1. Next, press your hands firmly on your hips and bend slightly toward the mirror as you pull your shoulders and elbows forward. This will make any changes more prominent. Use the pads of the fingers of your other hand to check the breast and the surrounding area-firmly, carefully, and thoroughly.
Some women like to use lotion or powder to help their fingers glide easily over the skin.
Feel for any unusual lump or mass under the skin. Feel the tissue by pressing your fingers in small, overlapping areas about the size of a dime. Other women feel more comfortable with another pattern. The important thing is to cover the whole breast and to pay special attention to the area between the breast and the underarm, including the underarm itself. Check the area above the breast, up to the collarbone and all the way over to your shoulder.
