In the majority of cases of macromastia, surgery is medically unnecessary, depending on body height. Topical treatment includes regimens of ice to cool the breasts.Treatment of hyperprolactinemia-associated macromastia with D2 receptor agonists such as bromocriptine and cabergoline has been found to be effective in some, but not all cases. Danazol, an antiestrogen and weak androgen, has also been found to be effective in the treatment of macromastia.When hypertrophy occurs in adolescence, noninvasive treatments, including pharmaceutical treatment, hormone therapy,  and steroid use are not usually recommended due to known and unknown side effects. Once breast growth rate has stabilized, breast reduction may be an appropriate choice. In some instances after aggressive or surgical treatment, the breast may continue to grow or re-grow, a complete mastectomy may be recommended as a last resort. Pregnancy is recognized as the second most common reason for hypertrophy. When secondary to pregnancy, it may resolve itself without treatment after the pregnancy ends. Society and culture
Difficulties
Extremely large breasts are a source of considerable attention. Some women try to hide or mask their breasts with special clothing, including minimizing bras. Women with this condition may be subject to psychological problems due to unwanted attention or harassment. Depression is common in those affected. In the case of a 12-year-old Japanese girl reported in 1993, her "massively enlarged" breasts caused her "intense psychological problems, incapacitating her in school activities and social relations".
Breast hypertrophy is a rare medical condition of the breast connective tissues in which the breasts become excessively large. The condition is often divided based on the severity into two types, macromastia and gigantomastia. Hypertrophy of the breast tissues may be caused by increased histologic sensitivity to certain hormones such as female sex hormones, prolactin, and growth factors. Breast hypertrophy is a benign progressive enlargement, which can occur in both breasts (bilateral) or only in one breast (unilateral). It was first scientifically described in 1648. Description and types
The indication is an excess breast weight that exceeds approximately 3% of the total body weight. There are varying definitions of what is considered to be excessive breast tissue, that is the expected breast tissue plus extraordinary breast tissue, ranging from as little as 0.6 kilograms (1.3 lb) up to 2.5 kilograms (5.5 lb) with most physicians defining macromastia as excessive tissue of over 1.5 kilograms (3.3 lb). Some resources distinguish between macromastia (Greek, macro: large, mastos: breast), where excessive tissue is less than 2.5 kg, and gigantomastia (Greek, gigantikos: giant), where excessive tissue is more than 2.5 kg. The enlargement can cause muscular discomfort and over-stretching of the skin envelope, which can lead in some cases to ulceration.Hypertrophy of the breast can affect the breasts equally, but usually affects one breast more than the other, thereby causing asymmetry, when one breast is larger than the other. The condition can also individually affect the nipples and areola instead of or in addition to the entire breast.
