Frequently Asked Questions about Cancer
Why do cancer cells develop?
- Published: 27 June 2012
DNA is present in every cell and directs all activities. Most of the time when DNA becomes damaged the body is able to repair it. Not so in cancer cells. People can inherit damaged DNA, which accounts for inherited cancers. More often, though, a person’s DNA becomes damaged by exposure to something in the environment, like smoking or prolonged exposure to the sun.
