Washington: Insufficient sleep is linked to more aggressive form of breast cancers and the likelihood of its recurrence, a study has revealed.The study, led by Cheryl Thompson, Assistant Professor at Case Western Reserve University School of Medicine, analysed medical records and survey responses from 412 post-menopausal breast cancer patients with Oncotype DX.Oncotype DX is a widely utilized test to guide treatment in early stage breast cancer by predicting likelihood of recurrence.Researchers found that women who reported six hours or less of sleep per night on average before breast cancer diagnosis had increased Oncotype DX tumour recurrence scores."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," Dr. Thompson said.
