Circadian rhythms maintain homeostasis of the body through hormonal, metabolic and cell cycle regulating cell proliferation. In turn, these are mediated by psychological conditions that may affect its operation and leave the body susceptible to diseases like cancer. The aim of this article is to review the relationship of circadian rhythms to cancer; with emphasis on those rhythms that are related to behaviors such as sleep-wake rhythm and the circadian rhythm of cortisol. This review will seek to identify, potential impact on the incidence and prognosis of cancer. Also psychobiological mechanisms that maintain the relationship between the circadian rhythms and cancer will be discussed.
