summary: 'When cells grow in your body, they divide into exact copies of themselves. But sometimes cells grow abnormally. Often this isn’t dangerous, and they grow what is known as a benign tumor. But at other times, cells start to grow in an “out-of-control” way, invading other parts of the body. This is called cancer.'
