Sleep duration, melatonin, and breast cancer: compliment and complement.
In an interesting study, Verkasalo et al. (1) found some support for lower breast cancer risks in long sleepers in Finland. The authors appropriately embedded their discussion in the existing literature, insofar as they point to prior studies into possible links between long sleep and mortality. Indeed, the recent review by Youngstedt and Kripke (2) evinced that sleeping beyond 8 hours could be...
متن کاملSleep Duration and Breast Cancer Phenotype
Emerging evidence suggests that short sleep is associated with an increased risk of cancer; however, little has been done to study the role of sleep on tumor characteristics. In this study, we evaluated the relationship between sleep duration and tumor phenotype in 972 breast cancer patients. Sleep duration was inversely associated with tumor grade (univariate P = 0.032), particularly in postme...
متن کاملSleep duration, melatonin and breast cancer among Chinese women in Singapore.
BACKGROUND Sleep duration has been hypothesized to be inversely associated with breast cancer risk, possibly due to greater overall melatonin production in longer sleepers. However, data are inconclusive from the three studies conducted in Western populations on sleep duration and breast cancer risk. METHODS We investigated the relationship between self-reported usual sleep duration determine...
متن کاملSleep duration and breast cancer: a prospective cohort study.
Breast cancer incidence has increased during recent decades for reasons that are only partly understood. Prevalence of sleeping difficulties and sleepiness has increased, whereas sleeping duration per night has decreased. We hypothesized that there is an inverse association between sleep duration and breast cancer risk, possibly due to greater overall melatonin production in longer sleepers. Th...
متن کاملMelatonin, sleep disturbance and cancer risk.
The pineal hormone melatonin is involved in the circadian regulation and facilitation of sleep, the inhibition of cancer development and growth, and the enhancement of immune function. Individuals, such as night shift workers, who are exposed to light at night on a regular basis experience biological rhythm (i.e., circadian) disruption including circadian phase shifts, nocturnal melatonin suppr...
