Forgive my frankness: B12 is a normal body component essential to your health. Everything that really causes cancer is either a mutagen (ionizing radiation or very reactive chemicals) or a promoter (serious tissue damage / regeneration). Don't waste your time on reports of bad / junk science -- EVERYTHING "causes cancer" if you publish only your statistical flukes.

Thanks for the follow-up. In California, EVERYTHING has been "shown to cause cancer" because of lawyers. These studies haven't been performed for vitamins, for the same reason that no one has done a controlled study to see whether parachutes save lives during falls from airplanes. I'm glad you understand.
