When the data were stratified by sex, B6 and B12 as individual supplements were each shown to increase lung cancer risk by 30–40% in men (but not in women).

The greatest risk was found among men with the highest average daily dose of B6 (>20 mg/day was associated with an 82% greater risk) and B12 (>55 mcg/day was associated with a 98% greater risk) over the ten years preceding the study.

Thanks for the posting.   It validates the idea that you should get tested for deficiencies before you supplement.  If that is not possible, stick to real food and or follow the RDA  as issued by the government.
