Cheryl Thompson, PhD, and leader of the study, explained that not enough sleep was associated with aggressive tumors, as well as the possibility of cancer reoccurrence.

“We found a strong correlation between fewer hours of sleep per night and worse recurrence scores, specifically in post-menopausal breast cancer patients,” Thompson said. “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 cause of this association.”
