genetic changes. but their mutations are found everywhere in the world. and you see women who find out that they ve tested positive for the gene and then they go ahead and have a double masecto masectomy. what are the odds that you test positive that you will get breast cancer? is it a certainty? thank you, randi, for asking that. the predisposition increases your risk anywhere from 50% to 80% in your lifetime, but it is not a guarantee that you will get cancer. and you may go your whole life without cancer. so, it s a very unique position to be in to be at elevated risk without a certainty of cancer and having one of these mutations does not mean that you will get cancer. there is really tridance fork of evidence which range from increased surveillance, preventative medications and preventative vitamins to surgery. but when you hear some of
two genes that were discovered in the 1990s which serve to help protect our dna from damage. when a copy doesn t work properly, it greatly increases the risk for breast and oovarian cancer. but both brca 1 and 2 increase the risk but brca1 occurs more earlier and brca2 has more risk for men. who is most likely to have this gene? it s very important for one to really have a good understanding of their own family history. the greatest risks are in those women who have had or have a family history of early onset breast cancer before the age of 50, have a personal family history of ovarian cancer, multiple breast cancer, any male breast cancer and also certain ethnic risks are at elevated risks for carrying one of these
