Aug. 19, 2003 -- Obese women may be more likely to develop breast cancer largely because their bodies produce more estrogen than thin women do. New research suggests that the increase in breast cancer risk faced by obese postmenopausal women may largely be due to higher levels of estrogens circulating in their bodies.
Women may experience vaginal irregularities such as dryness or discharge. Men may experience abnormal growth of testes. Psychological side effects associated with Anti-Estrogen use include: insomnia, depression, anxiety, lethargy, and mood swings. A major concern with Anti-Estrogens has to do with the lowering of estrogen levels in the body. Decreased estrogen levels increase the risk of osteoporosis, which increases the risk of bone fractures.
