Obstructive sleep apnea as a risk factor for cancer

ERS 2022

People who suffer from obstructive sleep apnea (OSA) have an increased risk of cancer. This is also the result of a large study presented at the international congress of the European Respiratory Society (ERS) in Barcelona.1

OSA is a common sleep disorder in which the airway becomes partially or completely blocked during sleep and breathing stops several times a night. The consequences are loud snoring, wheezing, choking or daytime sleepiness. Risk factors include obesity, diabetes, smoking or large amounts of alcohol.

dr Andreas Palm from Uppsala University, who presented the study, explains: “It is already known that patients with obstructive sleep apnea have an increased risk of cancer, but it was not previously clear whether this is due to OSA itself or related risk factors for cancer , such as obesity, cardiometabolic diseases and lifestyle factors. Our results show that oxygen deprivation due to OSA is independently associated with cancer.”
