The Non-Genetics of Cancer

A clarifying poll from a couple UK organizations I've never heard of - Cancerbackup and Genes Reunited - shows that the overwhelming preponderance of people (in the UK, at least) think that cancer is largely hereditiary/genetic. In fact, this story says, 90 percent of cancers are entirely random. The biggest risk factor for cancer is not family history, as 60 percent of those polled believe, but age.
