I can see this because Vitamin E is one of the few vitamins that is stored in the body.

What doesn't cause cancer these days? :huh:

In a study from the University of Tampere, Finland, 36,265 adults provided blood samples which were frozen and stored. The age range of the subjects was 15 to 99, and they came from 25 population groups in various parts of Finland. After around 8 years, 766 subjects developed various forms of cancer. The levels of vitamin E and other antioxidants were found from the original blood samples of these subjects along with those of 1,419 non-cancer control subjects, matched for age, sex, and duration of sample storage.

The mean serum vitamin E concentration of cancer patients was on average 3% lower than those of healthy controls. The difference held statistical significance. Men in the lowest 60% and women in the lowest 20% of vitamin E levels had a 150% greater risk of developing cancer compared with those who had higher levels. Among men, non-smokers with low vitamin E levels had twice the cancer risk as other non-smoking men. Smoking men did not show a similar association. Among women, those with both low serum vitamin E and selenium levels had three times higher risk of hormone-related cancers.
