Breast cancer is the second most common type of cancer in women (after skin cancer), and can affect a number of different parts of the breasts.
Breast infections are most common among women who are breastfeeding. When the nipples become cracked and sore, bacteria can enter the breast from a baby's mouth.
Fibrocystic breast disease, commonly called fibrocystic breasts or fibrocystic change, is a benign condition in which a woman has painful lumps in her breasts.
