Two new studies show that people who suffer from sleep apnea may be at higher risk of developing cancer than people without sleep apnea. In one of the studies, Spanish researchers followed thousands of patients at sleep clinics and found that those with the most severe sleep apnea had a 65 percent higher chance of developing cancer of any kind. In the second study, researchers in Wisconsin studied about 1,250 government workers and found that those with the most breathing abnormalities at night had five times the rate of dying from any cancer than those without the sleep disorder.
