Its complicated.: Cancer is not just one thing. Cancer is hundreds of different diseases. Not just one. We know there are different triggers, different behaviors that place you at risk, there are different genes that increase the likelihood of cancer...we know LOTS of different things about LOTS of different cancers. But we don't know the one thing that is common to all cancers so that they can be prevented.
