While estrogen is often a hormone more associated with women, there are several reasons why tamoxifen, a drug used to block the effects of estrogen, may be used to treat men. Men who get breast cancer are often treated with a course of tamoxifen. It can also be useful to stop or reverse a condition called gynecomastia, where the breast tissue of adolescent boys or men grows and sometimes becomes uncomfortable. Another use is tamoxifen for men who take anabolic steroids, in order to block the large amounts of estrogen produced by their bodies once they stop taking them. One of the primary uses of tamoxifen for men is the treatment of breast cancer. While this type of cancer is fairly rare in men, the type that most men get involves tumors that are estrogen receptor-positive, meaning that estrogen encourages their growth. Since tamoxifen is a selective estrogen receptor modulator, or SERM, it helps to keep estrogen from binding to the proteins on these tumors and therefore inhibits their growth. There are also some less common but more serious side-effects - tell your doctor about any unusual vaginal bleeding, any pains in your leg or breathlessness, and any allergic-type reactions. The most common unwanted side-effects are hot flushes, and vaginal discharge and itchiness. Treatment options for breast cancer include surgery, chemotherapy, radiotherapy and hormone treatment. Often a combination of two or more of these treatments is used. Some breast cancers need the female hormone oestrogen to grow. The cells of these cancers have receptors on their surface that oestrogen can attach to and are called 'hormone receptor-positive' cancers. Tamoxifen works by blocking the receptors and this prevents oestrogen from reaching cancer cells, stopping them from growing. Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken.
