the JAMA study is right, few do. And yes, more is needed by professionals. However, that is what all of these women are saying - find someone (a doctor who HAS time) who can do this sort of analysis. They are out there, you just have to look farther. I read JAMA too, just FYI, for my research. Not everything is published. There are lots of things that many political scientists THINK happens, but there is no way to go about measuring it feasibly at this time or simply just no resources or no one interested in pursuing it further. Breast cancer is on BOTH sides of my family. I have a pedigree that I could show you (I could draw it out myself), but it doesn't matter, you are right on penetrant. Yes, it is autosomal dominant. However, these ladies aren't geneticists.
