5-1 Discussion: What Causes Cancer?

Imagine that you are having a discussion with two friends. One says, “Cancer is a disease of the cell cycle (mitosis).” The other says, “Cancer is a genetic disease.” Which one is right? Or are they both right? Explain.

In addition to genetics, the environment is a factor in cancer formation. Provide examples of lifestyle changes that may prevent cancer.
