Exercise and Cancer

By Dr. Mercola

Mounting evidence shows that exercise can not only help cancer patients get well but also help keep their cancer from recurring. Yet, few oncologists tell their patients to engage in exercise beyond their simple daily, normal activities.

And many cancer patients are reluctant to exercise, or even discuss it with their oncologist.

A recent study¹ by the Mayo Clinic investigated exercise habits among cancer patients and their clinicians' roles in providing related counseling, and found that:

"Participants overwhelmingly cited usual daily activities as their source of 'exercise.' Symptoms, particularly treatment-related, discouraged participation, with fear of harm being a significant concern only among younger women. Exercise was recognized as important for physical and mental well-being, but seldom as a means to mitigate symptoms.

...Although respondents preferred to receive guidance from their oncologist, none reported receiving more than general encouragement to 'stay active.' A lack of direction was typically accepted as a sanction of their current activity levels. Participants appeared less receptive to guidance from ancillary health professionals."

An Important Conversation You'd Be Wise to Have With Your Oncologist

Fear that exercise might be harmful appears to be largely unfounded, though it's certainly understandable. It can be difficult to be enthusiastic about exercise if you struggle with nausea, fatigue, and other detrimental side effects from the treatment. However, it may be helpful to focus on the benefits you can reap from exercise. For example, research has shown that exercising during and after cancer treatment can:

• Reduce your risk of dying from cancer
• Reduce your risk of cancer recurrence
• Boost energy and minimize the side effects of conventional cancer treatment (see additional listing below)

The fact that most oncologists overlook this vital aspect of their patients' care is highly unfortunate, especially considering how most patients defer to their recommendations. However, it's not unexpected. Conventional doctors are trained to prescribe drugs, not exercise.

Ideally, they'd prescribe exercise in the same manner drugs are prescribed – in specific "doses" and intervals. To do this properly, oncologists would be wise to develop relationships with personal trainers, and prescribe training sessions for their patients. If you have cancer, I would highly recommend discussing exercise with your oncologist, and/or work with a trained fitness professional who can help you devise a safe and effective regimen.

Exercise Needs to Be Part of Standard Cancer Care

A recent report issued by the British organization Macmillan Cancer Support² argues that exercise really should be part of standard cancer care. It recommends that all patients getting cancer treatment should be told to engage in moderate-intensity exercise for two and a half hours every week, stating that the advice to rest and take it easy after treatment is an outdated view.

This is good news for my OCDexercise lifestyle! Yay!
