Cancer risk declines in old age. I had to double-take that article, because a lot of cancers increase as you get older. "That’s because genetic mutations build up in cells over years and decades, and ultimately drive the development of cancer." The theory is that when your cells get too old, they are too old to proliferate like a cancer cell should. “Aging cells lose their capacity for renewal and therefore for the runaway growth that happens in cancer.” That sounds like a George Burns joke – when you get too old for cancer. That's sugoi, I guess.
