Glad to see interest in hereditary breast and ovarian cancer. But, please get the facts straight. It is a MUTATION of a gene. Not a case of "if you have the gene". Everyone has the gene! Also, the mutation can be passed from the father to the son or daughter - an important fact to keep in mind and not stressed enough. In my case, my mom and I have the mutation. If my brother has it, then his daughter has a 50/50 chance of having the mutation. This is too often not stressed by doctors who think only women are affected by the mutation of these genes.
