    How can cancer develop in really healthy people taking good care of themselves?

    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.

    These articles address your question -

    Why don't we all get cancer? - Cancer Research UK
    Questions People Ask About Cancer - American Cancer Society

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