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. But they do know that some breast cancer cells are sensitive to estrogen. In order to fuel that growth, estrogen must attach itself to those breast cancer cells. Doctors think that tamoxifen stops estrogen from attaching to the cell. No estrogen means no growth for these types of breast cancer cells. Tamoxifen also keeps healthy breast cells from growing and multiplying. That way, it also reduces the number of cells that could become cancer. In a study of more than 13,000 women at high risk for breast cancer, scientists found that women who took tamoxifen for 5 years had fewer breast cancers than women who took a placebo. Newer research suggests that taking the drug for 10 years lowers the risk even more. Amoxicillin ear drops Doxycycline 50 mg capsule Buy metformin without doctor Jun 27, 2017.

Tamoxifen and raloxifene are the only drugs that are approved in the US to help lower the risk of breast cancer, although for some women, drugs called aromatase inhibitors might be an option as well.

Tamoxifen can be taken whether or not you have gone through menopause, but raloxifene is only approved for post-menopausal women. Both of these drugs block estrogen in breast cells, which is why they can be useful in lowering breast cancer risk. To lower the risk of breast cancer, these drugs are taken for 5 years. The effect of these drugs on breast cancer risk has varied in different studies. When the results of all the studies are taken together, the overall reduction in risk for these drugs is about 40% (more than a third). These drugs lower the risk of both invasive breast cancer and ductal carcinoma in situ (DCIS). Although a medicine that cuts your risk by about 40% sounds like it must be a good thing, what it would really mean for you depends on how high your risk is in the first place (your baseline risk).

There are an estimated 29 million women at increased risk for breast cancer in this country, and tamoxifen may offer another alternative to watchful waiting or prophylactic (preventative) mastectomy. Tamoxifen is classified as a selective estrogen receptor modulator (SERM) and works as an anti-estrogen: While the hormone estrogen promotes the growth of breast cancer cells, tamoxifen works by blocking estrogen from attaching to estrogen receptors on these cells.
