NBC NATIONAL NEWS — A new study reveals the problems associated with sleep apnea go way beyond loud snoring.
Researchers at the University of Wisconsin in Madison found people with severe sleep apnea are five times more likely to die from cancer. The association was stronger among people who were not obese.
Experts stress there is no proof that apnea actually causes cancer, but animal studies have shown that inadequate oxygen increases tumor growth.
Sleep apnea has already been shown to raise the risk of diabetes, heart attack and stroke.
