And Reap the Benefits of Exercise

Walking for three to five hours per week at a moderate pace is a great way to stay physically active.

The new paradigm for cancer survi­vors highlights the importance of staying active to help reduce cancer-related fatigue, pain, and other side effects of cancer treatments. This new model also promotes healthy survivorship and improved quality of life. While, histori­cally, people with cancer were told to rest and avoid exercise, mounting re­search now demonstrates the benefits of maintaining or adopting a physically active lifestyle during treatment.

Who Can Benefit?
Cancer survivor­ship experts agree that staying active is safe and can help alleviate certain side effects and improve quality of life dur­ing cancer treatment and beyond. In addition to helping fight fatigue and reduce pain, exercise during treatment has been shown to help preserve muscle mass, prevent unwanted weight gain, and boost fitness levels, muscle strength, and flexibility.

While a large percentage of the research on exercise during cancer treat­ment focuses on women with breast cancer, studies looking at survivors with other diagnoses are growing. For ex­ample, a recent study found that not only was resistance exercise safe for people with head and neck cancer undergoing radiation treatment, but it also resulted in reduced fatigue and improved quality of life for these survivors.

Another study showed that six weeks of a home-based fitness program, which included walking and balance exercises, following surgery benefitted non-small cell lung cancer survivors. The survi­vors who participated in this exercise program reported reduced levels of cancer-related fatigue while rehabilitat­ing from surgery.

Exercise is beneficial for both older and younger people undergoing cancer treatment. A study of older individuals with cancer found that exercise reduced memory loss, improved fatigue, and helped ease the total burden of treat­ment side effects.

How to Get Started
Moderate intensity exercise is best for cancer survivors, as it provides the most benefits with the least likelihood of harm. You should adjust your exercise intensity and duration so that you’re active without overdoing it. Intense exercise or “overtraining” has been shown to actually suppress the immune system. Start slowly and build up intensity and duration gradually. It’s important to balance activity and rest by taking days off or routinely scaling back the intensity or duration of exercise.

Walking for three to five hours per week at a moderate pace is a great way to stay physically active, and it has been shown to reduce recurrence risk of some cancers. You don’t have to do it all at once, though. Three 10-minute walks can be just as effective as one 30-minute walk. Yoga has also received attention for helping reduce anxiety, stress, and depression.

It’s a good idea to talk with your doctor before starting an exercise pro­gram. Once you have clearance from your doctor, you might consider seek­ing out a personal trainer or fitness instructor who has experience working with cancer survivors. Many hospitals and cancer centers offer yoga, Pilates, Qigong, aquatics, strength training, cardio, and other types of group exer­cise classes you can try.
