What's wacky is that both my husband and I developed skin cancer in the exact same spot on our face, within a month of each other, this year. Maybe there *are* environmental factors at play. We both eat fairly healthy, but we do love our (acrylimide-loaded) french fries from time to time, and we bought our beach house in 2003, and maybe didn't use enough sunscreen...

Strange that we both got it together. My husbands only 39! (i'm somewhere near that, but not tellin.)
Luckily we caught it early enough for it to be completely benign, but what a scare. Very interesting concept that the cancer's already there, and it's your immunity response that prevents it from growing. I can see diet playing a part with that angle.
