The Cancer Conundrum

You'll have to pardon my crudeness and ignorance, but I just read that oral sex causes cancer and beer cures it. Isn't this sort of like nails poisoning you and hammers providing the antidote? What I'm driving at is, if cancer is caused and cured by two things that go hand in hand, did it ever really exist?
