Stand facing a mirror. With your arms down at your sides, turn side to side. Inspect both breasts for any changes in the skin or nipples.

Raise you hands above your head and turn side to side while watching closely in the mirror and inspect each breast.

Place hands palm to palm and press together so that you can feel your chest muscles tighten. Look for any changes in the shape or contour of your breasts.

Next, with your hands firmly on your hips, bow slightly toward the mirror as you pull your shoulders and elbows forward. Again, look for changes in the shape or contour.
