I guess every one does in a way though. I sought out the geneticist myself. She worked in the cancer center where my Onc was but he certainly didn't think of it and was surprised I tested positive. We are insured through my husbands co. and had to pay $200. of it. Be sure you go to a board certified counselor. There is a website of course...
http://www.abgc.net/english/view.asp?x=1 is the one I found - they have lists of counselors if you have to do it by yourself.
I think after the work up of past family history I had only 16% possibility. So when I was positive even I was surprised. History gets fuzzy real fast though! It was hard to get information. My son was negative, my daughter positive. But now we know and that does help!
Hope this helps....
