How is it possible that healthy people can get cancer? - cancer

Despite the right of peoples to healthy eating and healthy foods with good exercise, as it is possible that these caregivers themselves have cancer?

But it is believed that the opposite? In other words, I think that people get do not pay attention to their health and fatty, unhealthy foods cancer. It does not make sense when healthy people like healthy non-smoking, healthy people become ill from lung cancer.

I know that causes cancer is to eat unhealthy foods and not many healthy activities.

But my question is ......
What causes lung cancer in nonsmokers and take care of your health? The wife of actor Christopher Reeve (Dana Reeve) died from lung cancer, although a non-smoker and a very healthy man.

If you choose to answer my question, not with "life" or "that's is what it is like" or "respond to life is unfair." Please give a concrete answer to my problem and to develop.

Nature is in charge?
