Data in on benefits of preventative surgeries for some...

[Rich66]

I guess I was wondering whether with such a smaller amount getting the surgery, comparing percentages might be skewed. Another factor might be whether those that pursue surgery are more proactive on other fronts, healthwise.
But..I imagine in any organ specific cancer, removal of the organ pretty much removes that cancer risk.
I looked at the JAMA article and it didn't seem to footnote risk reduction of prophylactic mastectomy in non-BRCA types. Is it around 7%?
In one of those glass half empty/full analyses, the BRCA tag actually doesn't seem as damning as it might seem.
