The Evolution of Cancer

There are some defining characteristics that all cancers share, which is sort of kind of a lot about what you're talking about. So using that, how does that inform controlling our environment in a way that's going to affect testicular cancer and breast cancer? Are there certain patterns of life that are going to affect all cancers similarly? And now that I asked the question, we also have to have the caveat that we really don't have any evidence to show that certain activities prevent cancer because we're on the precipice of this type of theory.
