Recent cancer cancer studies suggest that regular exercise has a major impact on survival.
So, walking for only 30 minutes a day, it is likely to increase the chances of almost half the fight against cancer.
Research was completed by Harvard University, where 992 men with cancer of the third stage were experimented and had spread to nearby nurses for seven consecutive years.
The third stage is the second most advanced form of cancer, which means it is great and is growing rapidly.
Patients who did 30 minutes’ moderate exercise five days a week and ate healthily were 42 per cent less likely to die. They also lived longer if the cancer returned.
The second study, by Australian researchers, looked at 194 women who had recently undergone surgery to remove breast cancer.
Half of patients were told to do 180 minutes’ moderate activity a week for at least eight months – although many carried on for longer.
The other half continued about their normal lives and both groups were examined after eight years.
The team from the Queensland University of Technology in Brisbane found that women who had exercised were 55 per cent more likely to still be alive.
The majority of patients in both studies did brisk walking as their main activity but heavy cleaning, gentle cycling and mowing the lawn also counted.
Scientists believe that even moderate exercise can slow tumour growth or prevent their returning by reducing levels of hormones.
They include insulin, which helps tumour cells multiply, as well as oestrogen in women, which encourages the development of breast cancer.
Exercise is particularly important for bowel cancer as it reduces inflammation, which can lead to cells multiplying and forming tumours. It also prevents patients becoming obese, as fat tissue produces hormones that stimulate tumour growth.
The bowel cancer study was presented at the American Society of Clinical Oncology conference in Chicago, the world’s largest cancer meeting.
