Snoring, Lack of Sleep Might Affect Breast Cancer Survival Rates
A new study published in the Journal of Clinical Sleep Medicine indicates that women who do not get adequate sleep and who frequently snore when they do sleep may have a poorer prognosis for breast cancer survival.
While previous data from various studies suggested a link between poor sleep quality and/or lack of sleep and an increased cancer risk, "the relationship between sleep and cancer outcomes has not been well characterized," according to the new study's authors. In light of the fact that breast cancer is the most common form of cancer among women in the United States, and a quarter-million new cases of invasive breast cancer are diagnosed in the U.S. each year, this new research on survival rates could perhaps open fresh areas of both research and treatment in years to come.
One striking take-away from the study: When compared with women diagnosed with breast cancer who infrequently snored and who got 7 to 8 hours of quality sleep each night, women with breast cancer who slept for less than 6 hours each night and who snored more than 5 nights a week were two times more likely to die from the disease.
