Many women do not learn much about breast health unless they breastfeed or have a problem that needs medical attention. Becoming familiar with breast anatomy and how the breasts function can help you understand the normal changes that occur during your lifetime. This is a good first step in learning about breast cancer and other conditions that affect the breasts.
