Two studies published this year have shown better outcomes in cancer for people who exercise more. Both studies were in people who developed colon cancer and found that the outcomes were greatly improved in people who exercised both before and after their diagnosis.

Walking prescribed for cancer patients
As a result, Dr John L Marshall MD, a cancer specialist at Georgetown University Hospital, Washington DC prescribes walking for his cancer patients. He advises patients to get a dog in order to make sure they walk regularly. He said the research showed that the reduction in patients’ chances of dying from colon cancer was greater than could be obtained by chemotherapy. He added that exercise both before and after diagnosis produced the greatest benefit, but even taking up exercise afterwards proved beneficial, showing again, that it’s never too late to start. He says he tells patients:
Walking protects against other cancers too
Other research have found that walking delayed progression of disease in men diagnosed with localized (not spread) prostate cancer. Of particular interest was the finding that brisk, as opposed to leisurely, walking produced the greatest benefits. There was a 57% lower rate of progression in the men who walked briskly for 3 hours a week or more, compared with those who walked at a leisurely pace for less than 3 hours a week.
Another study found that brisk walking reduced the chances of developing breast cancer after the menopause (the most common time to develop the disease). They also found that stepping up the level of activity after the menopause, to more than half an hour every day, was more protective than continuance at a lower intensity.
Ward off diabetes by walking
Prediabetes is a condition often seen in overweight and obese people, where there is raised blood glucose and resistance to the effects of insulin. If the effects seen in prediabetes are not reversed, it will inevitably progress to type 2 diabetes, and the negative impact on health which that disease brings.
So whether you are currently healthy or battling diseases like cancer or Alzheimer’s, the message is clear, get a dog and start walking!
