Megace (generic name, megestrol acetate) is one of a class of drugs called anti-estrogens.
Megace works by blocking the growth-stimulating effects of estrogen on cancer cells containing receptors for estrogen. When estrogen-dependent breast cancer cells are "starved," their multiplication is inhibited.
Another benefit of Megace is that it can enhance the appetite of cancer patients who have lost appetite and weight.
