Two recent studies in overseas indicates those who have sleep apnea have a higher risk of cancer. Sleep apnea is stopping breathing during sleep characterized by snoring and excessive sleepiness. This findings are scheduled to be presented at the American Thoracic Society conference in San Francisco. Scientists considered the findings as something surprising, as reported by the New York Times.
The scientists noted, sleep apnea is a sleep disorder that now affects nearly 28 million people in the United States. Lack of oxygen supply to the brain and other organs during sleep could trigger tumor development.
The first study, conducted by experts at the University of Wisconsin School of Medicine and Public Health for over 22 years, found that severe respiratory problems at night increases the likelihood of death from cancer by 4.8 times, rather than people who do not have breathing problems . People with moderate apnea found to have twice risk of death.
While other studies of the Spanish Sleep Network in Spain said that the incidence of cancer is higher in people who have sleep apnea. In his study, researchers include 5,200 men, who were observed for about seven years.
These studies track the depletion of oxygen in people with sleep disorders or sleep apnea. The results showed that people whose oxygen levels drop below 90 percent to 12 percent of total sleep time, has 68 percent greater chance of getting cancer, than people who do not have difficulty breathing at night.
Sleep apnea is also widely known associated with obesity, diabetes, hypertension, heart attacks and stroke.
