Simple lifestyle improvements - such as a good night's sleep and regular exercise - may be all it takes to dramatically reduce your chances of getting cancer.
Regular exercise 'significantly' reduces the risk of cancer, as does a seven-hour sleep, say researchers. Overall, a healthy lifestyle can reduce your chances of developing cancer by 20 per cent, or one-fifth.
Researchers from the US National Cancer Institute emphasise the importance of seven hours' sleep. A disturbed and sleepless night can undo all the good achieved from exercise.
The research team analysed the lifestyles of around 6,000 women over a 10-year period, during which time 604 developed cancer, and 186 of these with breast cancer. Women who regularly suffered a sleepless night were 47 per cent more likely to develop cancer.
