Study links sleep duration and frequent snoring to poorer breast cancer survival
American Academy of Sleep Medicine

A new study reports that short sleep duration combined with frequent snoring reported prior to cancer diagnosis may influence subsequent breast cancer survival.

Results show that women who typically slept less than the recommended 7 hours of sleep per night and were frequent snorers in the years before their cancer diagnosis experienced a poorer cancer prognosis. The findings were especially robust for women who were diagnosed with breast cancer. Breast cancer patients who reported sleeping 6 hours or less per night and snoring 5 or more nights per week before their diagnosis were 2 times more likely to die from breast cancer (hazard ratio = 2.14) than patients who reported sleeping 7 to 8 hours per night and rarely snored.
