¶ … cancer genes that are associated with breast cancer. Scientists have known for years that the most common breast cancer genes are BRCA1 AND BRCA2, but there are many more than those two genes that scientists now much cope with. Another aspect of the focus is on whether or not to tell a woman that she has genes that might lead to breast cancer; the ethical questions are serious and this is complicated by the fact that ovarian cancer and breast cancer "share genetic risk factors." The overall problem is breast cancer, but within the problem of breast cancer is determining which genes are likely to cause tumors and which are present but do not necessarily lead to breast cancer. The identification of BRCA1 and BRCA2 was thought to hold the keys to identifying those women who had those genes as possible breast cancer victims. But with the "rapid expansion of next-generation DNA sequencing," scientists have learned that there are perhaps "dozens" of additional genes that could be linked to breast cancer (Kean, 2014, p. 1457)....
What is being investigated is why certain genes "shut down" and why the DNA can't repair a double strand break. Also being investigated is why certain mutations increase a woman's chance of cancer two and three-fold in terms of risk (Kean, 1458).
Breast Cancer Treatments Breast cancer is the most common cause of cancer related deaths in females and its rising incidence makes it the second most common cause of deaths due to cancer in both genders. Its incidence increases with the following risk factors, age and first degree relatives affected with the illness. However, only five to ten percent of all breast cancers are hereditary. The BRCA1, BRCA 2 and the p
roles do genes play in determining cell structure and function? How is gene expression regulated? Genes are composed of sequences of DNA which pass on the organism's genetic blueprint through the process of replication. "By serving as the blueprints of proteins in the body, genes ultimately influence all aspects of body structure and function... An error in one of these genes can lead to a recognizable genetic disease" (McCance &
A mutation of the gene causing colorectal cancer or epithelial ovarian cancer are major risk factors for ovarian cancer, and genetic testing within the laboratory can identify most of these. However, the women who possess these inherited genes are at less risk than those women who do not have any family history of ovarian cancer, and while the former group can be treated with advanced planning and genetic counseling,
Since the antigens are closely linked to race and ethnicity, it is much easier to find a biological match among people with similar ethnic and racial backgrounds than it is among any two randomly selected individuals. On the basis of tissue matching, organs from blacks will almost always go to blacks and organs from whites will almost always go to whites. Blacks, however, have a much higher incidence of
Antipsychotic Medication and the Physical Health Problems of the Patient With Mental Illness More and more attention is now being given to the mental disorders especially in U.S. And due to this increase in attention an increase has also been noticed in the treatment of these mental health issues (Zuvekas, 2005). About 30% of the total U.S. population that is between the ages of 18-52 is being affected by mental health
Individual Impacts Genetic Diagnosis Individual Impacts of Genetic Diagnosis The number of inherited disorders and risk factors that can be detected through genetic testing is increasing rapidly, and genetic testing may soon become a common component of routine medical care. Is behavioural medicine ready? For the first time, a sophisticated understanding of gene-environment interactions as manifested in the interactions among an individual's genetic predispositions, behaviour, and environment seems within reach.
