Another example of genetic testing is the BRCA1 and also BRCA2 gene testing. These tests are used to detect mutations in the BRCA1 and BRCA2 genes that enlarge the danger of developing
east and ovarian cancer. The BRCA1 and BRCA2 genes produce proteins that allow to suppress the growth of tumors, and mutations in these genes can lead to an increased risk of developing cancer.
In BRCA1 and BRCA2 gene testing, the DNA of the person being tested is studied to identify any mutations in the genes. If a mutation is found, the person may be at an increased risk of developing
east and ovarian cancer. The results of the test can then be used to inform medical decisions, such as whether to undergo increased surveillance or undergo...
