How can cancer develop in really healthy people taking good care of themselves?
MilonJones posted:
Hello friends,

A heavy smoker can develop lung cancer because of harmful chemicals overtime to his lungs. But sometimes, lung cancer can develop in a nonsmoker's lung. Or breast cancer can develop in a healthy woman's body.

Thanks a lot

Hi MilonJones -

This is a great question which continues to be examined by many doctors and researchers.

The simple answer is genetics, but still much more to be investigated.

Do you have any more thoughts about why some are affected with this terrible disease?
