BACKGROUND: Results have been mixed from 3 previous clinical trials of the use of tamoxifen for preventing breast cancer in high-risk women. A recently updated analysis from 1 negative study showed a decrease in the incidence of estrogen-receptor–positive breast cancer, adding support for the effectiveness of tamoxifen in some high-risk women. Tamoxifen therapy, however, is associated with significant adverse outcomes that may outweigh any benefits. POPULATION STUDIED: Recruitment took place among outpatients at breast screening centers, primary care offices, and family history clinics. The media and contact of relatives of women with breast cancer provided additional recruitment. Women aged 35 to 70 years met criteria for entry if their risk for developing breast cancer was at least double that for women between 45 and 70 years, at least 4-fold that for women between 40 and 44 years, and 10-fold that for women aged 35 to 39 years. Risk was determined by an unpublished alternative to the Gail model. "Nearly 90% of women at risk of breast cancer shun preventative drugs due to fear of side effects and 'fate'," reports the Independent Online. Current guidelines recommend that women thought to be at increased risk of developing breast cancer because they have a family history of the condition should be offered a drug called tamoxifen. Tamoxifen can reduce this risk, but the drug, which women usually have to take every day for 5 years, can cause side effects such as hot flushes, tiredness and nausea. A new study looked at 258 higher-risk women who had been recommended tamoxifen and referred to a specialist centre in England. The researchers found only around 1 in 7 women (14.7%) decided to take tamoxifen. Of the 258 women, 16 agreed to take part in follow-up interviews explaining the reasons why they did or didn't decide to use tamoxifen. The researchers found women with children were more likely to agree to treatment.

Tamoxifen, sold under the brand name Nolvadex among others, is a medication that is used to prevent breast cancer in women and treat breast cancer in women and men. In 2005, my mother was diagnosed with ovarian cancer and in 2006, my older sister faced a diagnosis of lobular breast cancer. Although both lived in Florida, I insisted they come to Houston to be treated at with my sister, I mentioned to her oncologist that I’d noticed an unusual discharge from my nipple. But based on my experiences and the specialized expertise of the radiologists, I decided to begin getting routine mammograms at . She advised me to make an appointment immediately to see Therese Bevers, M. When a world-class oncologist makes such a strong recommendation, I heed their advice. In 2012, my mammogram showed an area that necessitated a biopsy. Fortunately, the biopsy came back normal, but three years later, Dr. Bevers noted a suspicious area in the opposite breast. A second biopsy showed abnormal cellular changes, or atypical hyperplasia, but not cancer. At that point, I began to accept that I had an increased risk for breast cancer. Bevers had explained that my family and personal history placed me at a higher than average risk and discussed possibly starting a preventive therapy medication, such as tamoxifen, to reduce that risk. After all, I was in great health, led an active lifestyle, was at an ideal weight, ate a healthy diet and generally did all the right things to ensure that I would remain healthy for a long time. 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.
