There???s a lot to be said for lifestyle and risk but with the chance that I???m a carrier of a BRCA mutation (I???d love to know for sure but Tricare won???t send me for the test because I only have one 1st-degree relative with cancer ??? my mom is an only child, so I don???t have any aunts on her side!), I do think screening of some sort, starting now, is prudent.
