Stories such as theirs reveal the benefits of such screening. Angelina Jolie had a double mastectomy in February 2013 after discovering she carried the BRCA1 gene. If she were to take no action, a breast-cancer diagnosis was a near certainty (90 percent) in her future. Nearly two years after the double mastectomy, Jolie had her ovaries and Fallopian tubes removed to stay one step ahead of an ovarian cancer medical diagnosis.
At the core of Jolie’s decisions? Cancer genetic therapy.
The therapy does not expose certainties– not everybody with a mutation in a cancer gene will establish cancer, but the mutation greatly increases the threat.
Some of the common genes that might contribute to a cancer diagnosis consist of TP53, BRCA1, BRCA2 and PTEN. According to the American Cancer Society, mutations in specific genes are attributed to more than 50 hereditary cancer syndromes. Lots of people with the previously mentioned altered genes develop cancer at more youthful ages than the remainder of the population. Hereditary testing for those who are at high threat is now recommended and a standard of care in oncology today.
