Two recent studies indicate overseas, those who have sleep apnea have a higher risk of cancer. Sleep apnea is stopping breathing during sleep characterized by snoring and excessive sleepiness.
The findings are scheduled to be presented at the American Thoracic Society conference in San Francisco. Scientists call the findings as something of a surprise, 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 be expected to 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 in tingat found to have twice the mortality risk is higher.
While other studies of the Spanish Sleep Network in Spain to assess the incidence of cancer is higher in people who have sleep apnea. In his study, researchers enrolled 5200 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 who oxygen levels drop below 90 percent, to 12 percent of total sleep time, has a 68 percent greater chance of getting cancer, than people who do not have difficulty breathing at night.
Sleep apnea is also widely understood problems associated with obesity, diabetes, hypertension, heart attacks and stroke - conditions that are also associated with cancer.
