If you're at high risk of breast cancer, you may be able to improve your odds of staying cancer-free by taking certain medicines, an approach known as chemoprevention or preventive therapy. Medications for breast cancer chemoprevention are the subject of much ongoing research. Tamoxifen blocks the effects of estrogen — a reproductive hormone that influences the growth and development of many breast tumors. Tamoxifen belongs to a class of drugs known as selective estrogen receptor modulators (SERMs), and it reduces the effects of estrogen in most areas of the body, including the breast. In the uterus, tamoxifen acts like an estrogen and encourages the growth of the lining of the uterus. Tamoxifen is prescribed as a pill you take once a day by mouth. For breast cancer risk reduction, tamoxifen is typically taken for a total of five years. Also known as: Soltamox The following information is NOT intended to endorse drugs or recommend therapy.

Hormones are substances that function as chemical messengers in the body. They affect the actions of cells and tissues at various locations in the body, often reaching their targets through the bloodstream. The hormones estrogen and progesterone are produced by the ovaries in premenopausal women and by some other tissues, including fat and skin, in both premenopausal and postmenopausal women and men. Estrogen promotes the development and maintenance of female sex characteristics and the growth of long bones. Progesterone plays a role in the menstrual cycle and pregnancy. Estrogen and progesterone also promote the growth of some breast cancers, which are called hormone-sensitive (or hormone-dependent) breast cancers. Hormone-sensitive breast cancer cells contain proteins called hormone receptors that become activated when hormones bind to them. The drug tamoxifen can help prevent breast cancer in women at an increased risk of the disease. But many women who stand to benefit from tamoxifen do not take the drug—a pill—because of concerns about side effects, such as hot flashes and . To explore alternatives to oral tamoxifen that might have fewer side effects, researchers are testing a topical form of the drug in two clinical trials. These randomized placebo-controlled studies are evaluating a gel formulation of tamoxifen called 4-hydroxytamoxifen (4-OHT) that women apply directly to the breasts. The goal of this research is to find out if delivering a form of tamoxifen topically results in the same level of the drug in the breast but leads to lower levels of the drug in the blood and other parts of the body compared with oral delivery, according to Brandy Heckman-Stoddard, Ph. “With lower levels of the drug in the body, women would potentially have fewer side effects,” she added. D., of Northwestern University Feinberg School of Medicine led a small study that compared the proliferation of abnormal cells in the lining of the breast duct—a condition known as ductal carcinoma in situ (DCIS)—among women treated with the gel applied to the breast skin and women treated with oral tamoxifen. (In women with DCIS, the abnormal cells have not yet spread to other tissues in the breast.) “We found a similar reduction in the growth of DCIS cells from both the gel and the pill form of the drug, and the concentrations [of tamoxifen] in the breasts of women who were treated with the gel were quite good,” said Dr. Khan, who is leading one of the new clinical trials of the tamoxifen gel.
