I'm certainly not a trained scientist but when you consider that there are over 200 different kinds of cancer and they know certain things cause some of those cancers, there still must be some basic link that has escaped the best minds out there. (Remember I like things that can fit in boxes.) Tobacco, for an example, has been linked to many cancers but it doesn't cause cancer in everyone and if it does "cause" cancer the person doesn't get all the cancers it's linked to. So why do some that smoke a little get a cancer associated with cancer and why do some that smoke a lot never get any of the forms of cancer related to tobacco. Why if you smoke and you get OC, why don't you also get lung cancer and vice versa? So so many variables to consider yet "we" know tobacco causes cancer. Same with HPV but so far to a lesser extent.

Maybe one day...
