Femara, also known as letrozole, is a drug used for treating breast cancer in postmenopausal women. This therapy has several side effects, and one of them is weight loss. Femara is a potent hormone drug and only your physician can assess if it can be of benefit to you and in what doses.


Femara Facts

Mayo Clinic experts report that Femara targets effectively hormone-sensitive breast cancer. This specific type of cancer relies on high estrogen levels to survive and thrive. In postmenopausal women, estrogen comes from converting androgens. Femara blocks this biochemical reaction and lowers significantly the amount of estrogen in the body. The target is to deprive the cancer cells of estrogen. Hormonal therapy usually follows after surgical removal of the tumors. Your doctor may recommend using hormone therapy prior to an operation in order to shrink a tumor. If cancer has already spread, hormone therapy for breast cancer may shrink and control it. Many women take hormone therapy for breast cancer for five years or more.

Supportive Lifestyle and Diet

It is important to support yourself in an efficient way during your hormonal therapy.

Vegetables and fruit are good nutritional choices, and many of them contain antioxidants that may help you in your fight against cancer. Vitamin D deficiency is also a risk factor for breast cancer, so make sure you keep your daily intake within the optimum levels. You should also eliminate or seriously lower your alcohol consumption.
