What is involved in genetic testing for breast cancer?
Genetic testing on breast cancer involves examining blood sample to evidence of certain genetic mutations that have been shown to increase the chances of an individual to develop breast and ovarian cancer. Generally, genetic breast cancer testing is performed only for those who have an increased risk of developing these cancers based on a personal or family history. The testing process can be extremely emotional and those undergoing testing must usually consult with a genetic advisor before the test and after the availability of results. Scientists have found that when BRCA1 or BRCA2 genes mutate, they can lose the ability to maintain abnormal cell growth under control. Individuals with BRCA1 or BRCA2 mutations face a higher risk of developing breast and ovarian cancer than the general public. Because these mutations are hereditary, this risk may be Passed from parent to child. The confirmation or exclusion of the presence of these mutations provides valuable information about the chances of cancer development. If mutations are identified, an individual testedIt can develop a plan to minimize cancer risk as much as possible. It can also learn through testing whether it could pass on the mutation BRCA1 or BRCA2 to its children.
walking through the process of genetic testing on breast cancer can be very emotional. Positive results can lead to depression, anger, anxiety and many other complications in the tested individual and their loved ones. Even a negative result may not leave all tested individuals who feel completely calm. For the most part, because of its emotionally difficult nature, the test is usually performed only by Nati, who have a personal or family history of breast or ovaries cancer. Furthermore, those who are undergoing a test must usually meet the advisor before testing to discuss the possible consequences of a positive or negative outcome.
During the test process, the doctor draws a blood sample from the subject of the subject. The sample is then aboutDeslan to the genetic testing laboratory for analysis. It takes several weeks or even months to obtain results.
As soon as the test results are available, the tested individual must usually meet his genetic advisor. At this time, the advisor will offer emotional support and help interpret the personal importance of the test results. If the test reveals BRCA1 or BRCA2 mutations, the advisor will help the tested individual to explore the possibilities such as frequent cancer projection, preventive drugs or breast tissue removal.
