The United States Nurses' Health Study recently revealed results of a study indicating that extensive rotating night shift work over 15 years leads to a greater risk of developing haematopoietic cancer. Haematopoietic cancers, (the 2 most common types are leukaemia and lymphoma) account for 10% of all new cancer diagnoses. While this study admits that several occupational, environmental, lifestyle, and physiological factors can lead to a higher risk of a cancer diagnosis, "it is speculated that night shift work may suppress melatonin, which regulates the sleep-wake cycle and is a powerful antioxidant."
