Article From Article Directory Database Genetic Risk Factors in Breast Cancer Breast cancer is the most common cancer and the second leading cause of cancer deaths in women in the United States. In 2008, approximately 184,450 patients were estimated to be diagnosed with invasive breast cancer, and an estimated 40,930 were estimated to die of this disease. Furthermore, over 50,000 female carcinoma in situ breast cases would have been diagnosed. The etiology of breast cancer is poorly understood with multiple genetic and environmental factors involved in the initiation and progression of cancer. Scandinavian Twin Study: For years, there has been a hot debate as to whether the cause of breast cancer is genetic or environmental. Then in 2000 Nike Air Max 1 Mens Sale , Lichtenstein and his colleagues at the Karolinska Institute in Sweden published their study of 44,788 pairs of twins from the Swedish, Danish, and Finnish twin registries. In this study, they looked at cancer risk with 28 different types of cancers and did statistical modeling of genetic and hereditary contributions in eleven different cancer types. For breast cancer, they clearly showed that only 27% of breast cancers were due to genetic factors. This was an even lower hereditary component than other common cancers such as prostate and colorectal. This study and others have confirmed the fact that over 70% of breast cancers are influenced by environmental factors.BRCA genes: Although much attention has been made about hereditary breast cancer, only two genes are commonly tested for breast cancer risk assessment. These two genes are tumor suppressor genes named 锟紹RCA1锟?and 锟紹RCA2锟?that are involved with DNA repair. These two genes only account for about 5% of all breast cancers. Because of the Scandinavian twin study, most experts believed that there are other yet to be discovered genes involved with breast cancer. Because the chance of having a BRCA mutation in the general population is so low, genetic testing is not indicated in most patients. However Nike Air Max 90 Mens Sale , if a patient has a family history of breast cancer, then a mathematical model can be used to determine if BRCA testing is indicated. The likelihood of being a BRCA carrier increases with the number of relatives who had cancer and if the cancers occurred earlier in life. For example, in families with four or more cases of breast or ovarian cancer under the age of 60, over 80% are found to have a damaged version of BRCA1 or BRCA2. If a patient is a carrier of one or both of the BRCA1 and BRCA2 g. Cheap MLB Jerseys   Wholesale Jerseys   Wholesale Soccer Jerseys   Cheap Jerseys Wholesale   Cheap NFL Jerseys   Cheap NFL Jerseys   Wholesale Jerseys China   Wholesale Jerseys   Wholesale NFL Jerseys   Wholesale Nike NFL Jerseys
