Sleep Apnea

Sleep Apnea Linked to Higher Cancer Death Risk: People with mild sleep apnea -- five to 14.9 episodes of low or no oxygen in an hour -- had a 10 percent increased risk of cancer death, while those with moderate sleep apnea -- 15 to 29.9 episodes of low or no oxygen in an hour -- had double the risk of cancer death. Those with severe sleep apnea -- more than 30 episodes of low or no oxygen in an hour -- had a 4.8 times higher risk of cancer death.
