The<unk>  is susceptible to numerous benign and malignant conditions. The most frequent benign conditions are puerperal mastitis, fibrocystic<unk>  changes and mastalgia. Lactation unrelated to pregnancy is known as galactorrhea. It can be caused by certain drugs (such as antipsychotic medications), extreme physical stress, or endocrine disorders. Lactation in newborns is caused by hormones from the mother that crossed into the baby's bloodstream during pregnancy.<unk>  cancer<unk>  cancer is the most common cause of cancer death among women and it is one of the leading causes of death among women. Factors that appear to be implicated in decreasing the risk of<unk>  cancer are regular<unk>  examinations by health care professionals, regular mammograms, self-examination of<unk> s, healthy diet, and exercise to decrease excess body fat, and<unk> feeding. Male<unk> s Both females and males develop<unk> s from the same embryological tissues. Normally, males produce lower levels of estrogens and higher levels of androgens, namely testosterone, which suppress the effects of estrogens in developing excessive<unk>  tissue. In boys and men, abnormal<unk>  development is manifested as gynecomastia, the consequence of a biochemical imbalance between the normal levels of estrogen and testosterone in the male body. Around 70% of boys temporarily develop<unk>  tissue during adolescence. The condition usually resolves by itself within two years. When male lactation occurs, it is considered a symptom of a disorder of the pituitary gland. Plastic surgery Conventional mastectomy (top); skin sparing mastectomy and latissimus dorsi myocutaneous flap reconstruction, prior to nipple reconstruction and tattooing (bottom). Plastic surgery can be performed to augment or reduce the size of<unk> s, or reconstruct the<unk>  in cases of deformative disease, such as<unk>  cancer.<unk>  augmentation and<unk>  lift (mastopexy) procedures are done only for cosmetic reasons, whereas<unk>  reduction is sometimes medically indicated. In cases where a woman's<unk> s are severely asymmetrical, surgery can be performed to either enlarge the smaller<unk> , reduce the size of the larger<unk> , or both.<unk>  augmentation surgery generally does not interfere with future ability to<unk> feed.<unk>  reduction surgery more frequently leads to decreased sensation in the nipple-areola complex, and to low milk supply in women who choose to<unk> feed. Implants can interfere with mammography<unk>  x-rays images).
