According to Healio, short sleep duration and frequent snoring prior to a cancer diagnosis may shorten survival among postmenopausal women with breast cancer.
Amanda I. Phipps, MPH, PhD, assistant professor of epidemiology at University of Washington, and colleagues assessed the association between sleep characteristics prior to cancer diagnosis and subsequent cancer survival among postmenopausal women who participated in the Women’s Health Initiative.
The analysis included data from 21,230 Women’s Health Initiative participants, in whom a first primary invasive cancer had been diagnosed during follow-up. All women had provided information about sleep characteristics at baseline.
