Actually, Thermography is advertised as finding cancer before a mammogram can, by showing a hotter than normal area. So there should be Thermographys and mammograms taken every year, for years, to prove or disprove that theory. But who is going to pay for that? It would have to be up to individual women doing it on their own, paying for Thermography, and reporting the findings yearly on some site. Which is probably not going to happen. I just wish they had caught my cancer a lot sooner. Before I had breast amputation.
