Not getting a good night's sleep can significantly increase a man's chances of being diagnosed with prostate cancer.
This is according to studies carried out at the University of Iceland in Reykjavik.
Over a period of five years researchers compared the sleeping patterns of over 2,000 men aged between 67 and 96. It was discovered that those who reported severe sleep problems were twice as likely to develop the condition.
Study leader Dr Lara Sigurdardottir said sleep issues such as insomnia are very common and can have a major impact on a person's health.
"Women with sleep disruption have consistently been reported to be at an increased risk for breast cancer, but less is known about the potential role of sleep problems in prostate cancer," she added.
It is estimated that 40,000 men are diagnosed with prostate cancer in the UK each year, with around 10,000 dying from the disease.
