Sleep apnea linked to higher risk for cancer

People with sleep apnea have a higher risk of cancer, two new studies have found. In one of the new studies, researchers in Spain followed thousands of patients at sleep clinics and found that those with the most severe forms of sleep apnea had a 65-per-cent greater risk of developing cancer of any kind. The second study, of about 1,500 government workers in Wisconsin, showed that those with the most breathing abnormalities at night had five times the rate of dying from cancer as people without the sleep disorder.
