Several types of drugs interfere with estrogen’s ability to stimulate the growth of breast cancer cells. The best-known of these are selective estrogen receptor modulators (SERMs), which bind to estrogen receptors to block estrogen activity. Tamoxifen, a type of SERM, has been used for more than 30 years to treat hormone receptor-positive breast cancer.

What doctors and specialists treat colorectal cancer?
Aurora Health Care answeredThe best treatment of colorectal cancer requires a multidisciplinary team approach. As a cancer patient, you benefit from multidisciplinary case reviews, which can include specialists from various disciplines:
- Gastroenterologist: a physician specializing in diseases of the gastrointestinal tract
- Cancer Nurse Navigator: a registered nurse with special training who can help answer your questions and provide information on resources and support services
- Medical oncologist: a physician specializing in treating cancer with chemotherapy, hormonal therapy or immunotherapy
- Pathologist: a physician who examines tissues and cells under a microscope to determine if they are normal or abnormal
- Radiation oncologist: a physician specializing in treating cancer with radiation therapy
- Radiologist: a physician who uses x-rays and other imaging tests to diagnose disease
- Colorectal surgeon: a physician who specializes in the medical and surgical treatment of conditions that affect the colon, rectum, and anus
When is hormone treatment used for prostate cancer?
Patrick Maguire, MD, Oncology, answeredA minority of patients with initially localized prostate cancer will have their disease return in distant sites in the body following local treatment with radical prostatectomy (surgery to remove the prostate), brachytherapy (radiation delivered over a short distance), or definitive intensity modulated radiation therapy (IMRT; higher doses of radiation to target tissues, while minimizing the dose delivered to normal organs). Other patients may have cancer that's already metastasized (spread) to distant sites at the time of their diagnosis. For these groups of patients, the primary method of treatment is "hormone therapy."
Of the two main types of medications, luteinizing hormone releasing hormone (LHRH) agonists have the most potent effects on decreasing testosterone rapidly. However, urologists will often also add oral anti-androgen pills to LHRH agonists for total androgen blockade (TAB). Depending upon the aggressiveness of the cancer cells, these medications can kill a large proportion of cancer cells and prevent the disease from progressing for an average of one to three years. Unfortunately, these treatments for patients with metastatic prostate cancer aren't curative.
