Sort of. It would be more accurate to say pre cancerous cells arise and are killed by your body everyday. Cancer occurs after 7-70 mutations at critical DNA segments, these mutations accumulate over time (why cancers are more common in old age). Leukemias and hereditary cancers require the least mutations (why they occur in younger people). Usually when a mutant cell arises it under goes programmed cell death or is killed by the immune system. When a cell avoids both of these and divides without dependence on cellular regulators it’s cancer. These cells don’t always divide quickly enough to make you sick, and are generally said to be harmless. When they gain the ability to cause illness then they’re cancer.Oh god, it's WebMD in real life.
semi-related aside, I don't know how true this is and I'm sure it was wildly oversimplified because "god bless her, she's in the humanities," but someone told me that we all get mutant potentially cancerous cells every day and it's only sloppy internal housekeeping that lets it turn from a couple of genetic typos into a disease. Thinking of it in terms of how many millions of time your body did its job right is a lot more comforting than stressing about the one time it might fuck it up. And it makes people like "cancer survivor" Sarah Jean look like even bigger jackasses, which is very satisfying.
