I have been offered a mammogram as part of an intiative in the area to extend them to under 50s. I am part of a random group being offered it, but I am just not sure. Has anybody heard evidence that mammograms which squash the breasts and zap them with radiation can cause cancer? It sounds like a good offer, but I can't decide as I don't like the idea of it, but it could find something early? I had also heard something about people who have had unnecessary chemo and surgery following mammograms. My dilemma - any advice?
