People with severe sleep apnea are almost five times as likely to die of cancer than those who breathe easy while they sleep, according to a new study presented last week at the American Thoracic Society conference. The study, which tracked 1,500 people for 22 years, found that mild or moderate snoring also increases your risk of cancer death.
Sleep apnea reduces the oxygen level in your blood; to avoid suffocating, tumors grow new blood vessels, says study author F. Javier Nieto, M.P.H., M.D., Ph.D., of the University of Wisconsin-Madison School of Medicine and Public Health. These extra veins and arteries help existing tumors grow faster and give cancer cells more opportunities to spread through your bloodstream to new parts of your body.
