I appreciate the post.
But, on one hand, I dislike studies like these. There seems to be a philosophy in the minds of some folks - not all, thankfully - that if we women only (a) did self-exams; and (B) exercised and kept our weight down -- we would not get breast cancer; i.e., it's all our own fault!
Since getting bc, I'm sensitive to this - I don't want to be blamed for my bc.
