Sleep characteristics and risk of ovarian cancer among postmenopausal women
This study of almost 110,000 women as part of the Women’s Health Initiative (WHI) looks at sleep patterns and the effect on ovarian cancer incidence. The WHI began in 1991 with a total enrollment of 160,000 women looking at health issues for post-menopausal women mainly cancer, cardiovascular disease, and osteoporosis.
The findings from the review are that the overall risk of ovarian cancer is unaffected by sleep disturbance. However, the grade of cancer differs between those who describe their sleep as restful or very restful and those who don’t.
Women with insomnia have a higher incidence of invasive or high-grade serous ovarian cancer. Good sleepers are more likely to have low invasive borderline or low-grade serous ovarian cancer.
