Causes of Cancer

Causes of Cancer

You probably know a kid who had chickenpox — maybe even you. But you probably don't know any kids who've had cancer. If you packed a large football stadium with kids, probably only one child in that stadium would have cancer.

Doctors aren't sure why some people get cancer and others don't. They do know that cancer is not contagious. You can't catch it from someone else who has it — cancer isn't caused by germs, like colds or the flu are. So don't be afraid of other kids — or anyone else — with cancer. You can talk to, play with, and hug someone with cancer.
Kids can't get cancer from anything they do either. Some kids think that a bump on the head causes brain cancer or that bad people get cancer. This isn't true! Kids don't do anything wrong to get cancer. But some unhealthy habits, especially cigarette smoking or drinking too much alcohol every day, can make you a lot more likely to get cancer when you become an adult.
