Hello,

My dad was diagnosed with prostate cancer a few months ago. He has been the only one in the family. I am his daughter and i can't help but worry that he has a gene that he has passed onto me. His oncologist has never ever mentioned testing or anything of this sort. So I don't know how to go about this. What are the chances of him being a carrier and passing it to me?
