Insomnia doubles the risk of prostate cancer, study claims

John von Radowitz at The Independent:

Insomnia can double the risk of prostate cancer in older men, a study suggests. The risk rises proportionately with the severity of sleep problems, increasing from 1.6 to 2.1 times the usual level. The reason is not known. But a link has also been seen between insomnia and breast cancer in women.
