Breast

Mastitis
Mastitis is the medical term for inflammation of the breast tissue. It is typically caused by an infection in the milk ducts or breast tissue.

Breast cancer - from Natural Standard
In breast cancer, some cells begin growing abnormally. The cells divide more rapidly than healthy cells and may spread through the breast tissue to the lymph nodes or other parts of the body (metastasize). The most common type of breast cancer begins in the milk-producing ducts, but cancer may also occur in the lobules or in other breast tissue.

Breast conditions
There are a number of benign (non-cancerous) breast conditions that a woman may experience during her lifetime. It is estimated that 50-90% of all women experience some symptoms such as breast pain, lumps, or nipple discharge by the time they reach menopause.
