Hormone Therapy Drugs to Prevent Breast Cancer Recurrence

After primary treatment is completed, you may need to take hormone therapy drugs to control levels of estrogen and progesterone. Read about these drugs, how they work, and some common side effects.
Endocrine Therapies for Breast Cancer Treatment
Estrogen receptor-positive breast cancer can be treated with endocrine therapies, also called hormonal therapies. These drugs come in two classes: selective estrogen receptor modulators (SERMs)and aromatase inhibitors. These lower your estrogen levels, and may affect your fertility, as well as preventing a recurrence of breast cancer. Learn more about endocrine therapies for breast cancer.
What are Aromatase Inhibitors and How Do These Drugs Prevent Recurrence?
Arimidex, Aromasin, and Femara are three aromatase inhibitors given as follow-up treatment after primary treatment for estrogen-receptor positive breast cancer. Aromatase inhibitors prevent the production of estrogen by inhibiting the enzyme aromatase.
What Are SERMs - Selective Estrogen-Receptor Modulators?
SERMs are selective estrogen-receptor modulators, drugs that block natural circulating estrogen in breast tissues and other estrogen-sensitive tissues in your body.
Arimidex – Anastrozole – Aromatase Inhibitor for Breast Cancer
Arimidex helps prevent the production of estrogen, a hormone that fuels many breast cancer tumors. It is considered a hormonal treatment, and can help prevent recurrence of breast cancer in postmenopausal women.
Femara (Letrozole) -- An Aromatase Inhibitor
Femara (letrozole) is an aromatase inhibitor that can greatly reduce your risk of recurrence for estrogen-receptor positive breast cancer. If you've completed treatment and taken Tamoxifen for 2 to 5 years, letrozole can extend protection from cancer's return. Learn more about letrozole.
Tamoxifen - Hormone Therapy to Prevent Breast Cancer Recurrence
Tamoxifen is an estrogen suppressor, which helps lower the risk that breast cancer will return and improves survival rates. If you have been diagnosed with estrogen-receptor positive breast cancer, tamoxifen may be used as part of your follow-up treatment. Weighing the risks and benefits of taking tamoxifen may seem tricky, but most doctors agree that the benefits are much greater than the risks.
Aromasin - Breast Cancer Adjuvant Hormone Therapy
Aromasin is given to female breast cancer patients to lower estrogen levels and prevent recurrence of breast cancer. Many breast tumors are fueled by estrogen. If breast cancer cells are present in your system, they have much less chance to grow, if they can’t get any estrogen. Read about the differences between tamoxifen and Aromasin.
