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.
