Vitamin E May Raise Lung Cancer Risk
Supplements' Effect Surprises Researchers
Some vitamin supplements may increase the risk of lung cancer, especially among smokers, according to a University of Washington study.
A more than 77,000 people who take multivitamins, vitamin C, vitamin E and folate didn't show any decrease in risk, Dr. Christopher Slatore said. "Indeed, increasing intake of supplemental vitamin E was associated with a slightly increased risk of lung cancer."
During the four-year study, 521 people developed lung cancer. That's about 0.6 percent. Researchers said that rate would be expected for a low-risk group of people.
But they also found what was called a slight but significant association with vitamin E use and lung cancer, along with expected links to factors such as smoking or family history.
