Many changes will occur in your breasts during your lifetime. Yet, many women do not know much about their breasts unless they breastfeed or they have a problem. Learning about breast structure (anatomy) and how the breasts function can help you understand which changes are normal and which are not. This is a good first step to find out about breast cancer and benign (not cancer) breast conditions.
The breasts are made up of fat and breast tissue, along with nerves, veins, arteries and connective tissue that helps hold everything in place. Throughout puberty and menopause, the look, structure and function of the breasts change. This section describes these changes, explains breast cancer and other breast conditions and includes statistics.
