Exercise and sleep 'can lower risk' of cancer
Not getting enough sleep can reduce the benefits of having a healthy lifestyle, according to new findings.
Evidence presented at the American Association for Cancer Research's seventh annual International Conference on Frontiers in Cancer Prevention Research revealed a good night's rest is also vital to resisting cancer.
Lead investigator James McClain, a cancer prevention fellow at the National Cancer Institute, said physical activity had been shown to reduce the risk of various cancers, including breast cancer.
"Short duration sleep appears to have opposing effects of physical activity on several key hormonal and metabolic parameters, which is why we looked at how it affected the exercise/cancer risk relationship," he said.
Something of importance to women with breast cancer insurance is future treatment - and Mr McClain said the next step is to confirm the study findings and investigate them further.
A recent study from Washington University School of Medicine and Harvard University in Boston found females between the ages of 12 and 35 who exercise regularly have a much lower risk of developing breast cancer before menopause compared to those who do not.
