    Tamoxifen chemoprevention


    Chemoprevention is a way to prevent or delay the development of cancer by taking medicines, vitamins or other agents. Tamoxifen, the first chemoprevention drug to receive FDA approval, is the most well-known chemopreventive agent. Studies have shown that tamoxifen reduces a high-risk woman’s chances of developing breast cancer by as much as one-half. Some chemopreventive drugs can have severe side effects in some patients, which is an issue when considering long-term administration of a drug to healthy people who may or may not develop cancer. For this reason, most chemopreventive drugs are recommended solely for people at high risk of developing cancer because they are most likely to benefit from treatment. Persons at high risk of developing cancer include those with: Speak with your doctor about your risks for developing cancer, as well as the potential harms and benefits associated with taking chemopreventive agents.

    SAN ANTONIO—Chemoprevention with tamoxifen or anastrozole significantly reduces the risk of invasive breast malignancies in women with atypical ductal hyperplasia ADH, lobular carcinoma in. how to order viagra by mail Tamoxifen As Chemoprevention in BRCA1 and BRCA2 Mutation Carriers With Breast Cancer A Pilot Survey of Physicians The demonstration by the National Surgical Adjuvant Breast and Bowel Project that tamoxifen reduces breast cancer risk by approximately 50% for at least some groups of high-risk women was a milestone in the chemoprevention of breast cancer.

    Breast cancer is the most common type of cancer in women after nonmelanoma skin cancers, causing significant morbidity and mortality all over the world. In fact, it is estimated that roughly 40,000 women will die from this disease in 2013.1 The average woman in the United States has about a 12% to 13% risk of developing breast cancer in her lifetime. This year 230,000 women will be diagnosed with invasive breast cancer, and about 55,000 will be diagnosed with ductal carcinoma in situ (DCIS). The most significant risks factors for breast cancer are age and family history.1 Although screening for early detection is practiced routinely, providers rarely offer chemoprevention for breast cancer. There is reluctance among clinicians to discuss and implement chemoprevention or prescribe drugs for breast cancer prevention. The US Preventive Services Task Force recommends that high-risk women between the ages of 40 and 70 be assessed for their likelihood of developing the disease and should be offered chemoprevention if they are at low risk of thromboembolic disease and endometrial cancer.2 However, it is important to note that the task force suggests that women aged 60 and older are at high risk of developing complications from chemoprevention, so physicians should use precautions and tailor treatment to each patient’s case. Assessing Risk The Breast Cancer Risk Assessment Tool (also called the Gail Model Risk Assessment Tool), developed by the National Cancer Institute and the National Surgical Adjuvant Breast and Bowel Project (NSABP), helps estimate a woman’s risk of developing invasive breast cancer.3 The tool has been updated for black women based on the Contraceptive and Reproductive Experiences study and for Asian and Pacific Islander women in the United States based on the Asian American Breast Cancer Study.3 The risk assessment tool consists of seven questions (see sidebar on page ••) and can be found as an interactive tool at 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.

    Propranolol is used to treat high blood pressure, irregular heart rhythms, pheochromocytoma (tumor on a small gland near the kidneys), certain types of tremor, and hypertrophic subaortic stenosis (a heart muscle disease). It is also used to prevent angina (chest pain), migraine headaches, and to improve survival after a heart attack. Propranolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure. High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure.
