This summary table contains detailed information about research studies. Summary tables are a useful way to look at the science behind many breast cancer guidelines and recommendations. However, to get the most out of the tables, it’s important to understand some key concepts. Introduction: Tamoxifen and raloxifene are the only drugs approved by the U. Food and Drug Administration (FDA) to lower the risk of breast cancer in women at high risk. The use of risk-lowering drugs may also be called chemoprevention, although no chemotherapy is involved. Both tamoxifen and raloxifene can lower the risk of invasive breast cancer (tamoxifen by about 50 percent and raloxifene by about 38 percent) in women at high risk* . Both drugs also lower the risk of non-invasive breast cancer, such as ductal carcinoma in situ (DCIS), in women at high risk . Raloxifene has fewer harmful side effects than tamoxifen and may be a better choice for some women . *High risk is defined as having a 1.67 percent or greater chance of getting breast cancer in the next 5 years, as calculated by the Breast Cancer Risk Assessment Tool (the Gail model) . Both pre- and postmenopausal women can take tamoxifen. Study selection criteria: Randomized controlled trials with at least 500 participants, pooled analyses and meta-analyses. amoxicillin warfarin Evista isn't used to treat breast cancer after it's been diagnosed. Evista also won't work on hormone-receptor-negative breast cancer. Evista is a pill that is taken once per day, with or without food. Ask your doctor which type of non-hormonal birth control would be best for you, as well as how long you should use this type of birth control after you stop taking Evista. Most doctors recommend taking Evista at the same time every day. The large STAR (Study of Tamoxifen and Raloxifene) trial compared Evista and tamoxifen, another SERM, to see if one medicine was better than the other at reducing the risk of invasive breast cancer in postmenopausal women. You should not take Evista if you are breastfeeding, pregnant, trying to get pregnant, or if there is any chance that you could be pregnant. You should use an effective non-hormonal type of birth control -- such as condoms, a diaphragm along with spermicide, or a non-hormonal I. The researchers also looked at whether postmenopausal women who took Evista or tamoxifen had similar quality of life. STAR trial results showed that Evista and tamoxifen offer the same reduction in risk -- both medicines lower the risk of invasive breast cancer by about 50%. Both medicines also offer the same overall quality of life.

Journal of the American. V. Craig Jordan. Raloxifene and tamoxifen had similar inhibitory effects on the growth of short-term tamoxifen-exposed breast tumors. Raloxifene and. Tamoxifen and raloxifene have been shown to reduce the risk breast cancer, but they can have their own risks and side effects. 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. This means that they act against (or block) estrogen (a female hormone) in some tissues of the body, but act like estrogen in others. Estrogen can fuel the growth of breast cancer cells. 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). STAR researchers used the Breast Cancer Risk Assessment Tool, developed by scientists at NCI and NSABP, to estimate a woman's risk of breast cancer using most of the above factors. In addition, for STAR, women diagnosed as having lobular carcinoma in situ (LCIS), a condition that is not cancer but indicates an increased chance of developing invasive breast cancer, were eligible based on that diagnosis alone, as long as their treatment for the condition was limited to local excision. al.; for the National Surgical Adjuvant Breast and Bowel Project (NSABP).
