Is it nature's fault that healthy people can get cancer no matter what? - how do healthy people still get cancer

I believe that nature to blame for the healthy people who care for themselves cancer. For example, healthy people who do not smoke, but some lung cancers. Or what about the healthy women diagnosed with breast cancer.

This is the deficiency of nature.
