Not that I want to downplay the cancer risks, but it is important to note that the people in these studies will have taken artificial vitamins, not vitamins from natural sources. Also, fat soluble vitamins (A D E K) need to be balanced against each other, just increasing one without increasing the others is certainly harmful.
Really, it's perfect if you take it all in with food and sunlight, but we do not live that kind of lifestyle any more. And if you eat a completely plant based diet like the PP, there's probably no way around artificial supplements anyway.

Edited to add that if you feel like seriously geeking out on this, I recommend starting with this page:
