Hormones that every woman has in her body -- estrogen and progesterone -- can serve as fuel for some types of breast cancer. They help the cells grow and spread. Hormone therapy, also called endocrine therapy, adds, blocks, or removes those chemicals to treat the disease.
Elyse Caplan remembers it well, that first conversation with her oncologist. She had just been diagnosed with stage IIB breast cancer, and they were discussing the game plan for treatment. If her oncologist mentioned "recurrence" -- the possibility that her cancer could return -- it was lost on her, she says.
"You sit through an hour-long appointment and take notes, but when the doctor says one thing that's very upsetting, you just freeze," she tells WebMD. "You're thinking, 'I'm going to lose my...
When you’re diagnosed with breast cancer, your doctor will test cells from your tumor to see if they have parts on their surfaces called receptors that use estrogen or progesterone. If they do, it means that they depend on these hormones to grow. In that case, your doctor will probably recommend hormone therapy as part of your treatment plan.
Tamoxifen is a pill that doctors have prescribed for more than 30 years to treat breast cancer. It works by blocking estrogen from attaching to the cancer cells.
Doctors first used tamoxifen to treat women whose breastcancer had spread in their bodies because it slowed or stopped the growth of the disease. The drug also lowers the chance that some early-stage breast cancers will come back. And it can lower the risk that a woman will get cancer in her other breast later on.
Women who are at high risk for breast cancer can take tamoxifen to try to lower their chances of getting the disease. It’s an alternative to watchful waiting or having surgery to remove a breast, called a mastectomy, before they get the disease.
