Exercise can stop cancer returning

EXERCISE is a "wonder drug" for cancer survivors and may even prevent the disease coming back.

Macmillan Cancer Support said physical activity should be "prescribed" by doctors after "hard evidence" showed it can significantly help recovery and prevent other long-term illnesses.

Rather than patients being told to "rest up" as in the past, doctors must encourage people to get moving.

A review of more than 60 studies for the charity found people undergoing cancer treatment -- and survivors -- could benefit from exercise.

During treatment, being active does not worsen people's fatigue and has positive effects on mood and wellbeing, the study said.

Once treatment has finished, exercise can reduce the impact of side effects, such as swelling around the arm, anxiety, depression, fatigue, impaired mobility and changes to weight.

"Long term, it is an effective way to help recover physical function, manage fatigue, improve quality of life and mental health, and control body weight," the report said.

The research also showed exercise had an impact on preventing recurrence of a few specific cancers.

Women with breast cancer who exercise for 150 minutes a week at moderate intensity have more than a 40pc lower risk of dying and recurrence of disease compared to women who are active for less than one hour a week.

Bowel and prostate cancer patients showed a similar patter of improvement.
