The evidence is strong! Physical activity is an effective intervention to combat cancer related fatigue and may help mitigate treatment related symptoms such as anxiety and depression, lymphedema and sleep quality – not to mention improve bone and muscle strength. A number of observational studies demonstrate the therapeutic benefit of physical activity during and after cancer treatment with a reduction in cancer recurrence of between 10-50% in a number of cancer types for patients who engaged in regular physical activity during and after cancer treatment.

Urban legends. Myths. Sometimes you should not believe everything you hear or read. The more emotionally charged the issue, often the bigger the myth. In my practice of providing cancer risk assessment and genetics education and counseling, patients often thank me at the end of the session and tell me they are going to explore the information more extensively at home on the internet. 

The importance of regular exercise and a healthy diet to maintain a healthy weight should not be underestimated. Healthy habits often need to be fostered. They need to be automatic and practiced consistently. The earlier they are developed, the bigger the benefits.
