Not Enough Sleep Contributes To Aggressive Breast Cancer

Lack of sleep can compromise your immune system and make you more vulnerable to infection. It may also have a deadly effect on post-menopausal women. According to researchers at University Hospitals Case Medical Center’s Seidman Cancer Center and Case Comprehensive Cancer Center at Case Western Reserve University in Cleveland, it increases the risk for aggressive breast cancer in women in this age group.

“This is the first study to suggest that women who routinely sleep fewer hours may develop more aggressive breast cancers compared with women who sleep longer hours,” says researcher Cheryl Thompson, Ph.D. “We found a strong correlation between fewer hours of sleep per night and worse recurrence scores, specifically in post-menopausal breast cancer patients. This suggests that lack of sufficient sleep may cause more aggressive tumors, but more research will need to be done to verify this finding and understand the causes of this association.”

The researchers found that women who got less than six hours of sleep nightly ran the greatest risk of suffering with aggressive tumors.
