Patients with sleep apnea experienced 3.4 times the risk of cancer mortality than those with no sleep apnea during a 20 year follow-up in Australia after controlling for leading risk factors. This is consistent with other observational studies. Researchers have been spurred by mouse studies that suggest hypoxia (lack of sufficient oxygen) may spur tumor growth. Also, all-cause mortality risk was 4.2 times higher in those with sleep apnea.
