Strong Evidence of Benefit
Anxiety The exercise prescription for reducing anxiety in cancer survivors is moderate-intensity aerobics 3 times per week for 12 weeks or twice a week for 6 to 12 weeks if resistance training is added. Resistance training by itself does not reduce anxiety.
Depressive symptomatology This effect is significantly reduced with the same prescription of moderate-intensity aerobics 3 times a week for at least 12 weeks or twice a week for 6 to 12 weeks if resistance training is added. Resistance training by itself does not reduce depressive symptoms.

Cancer-related fatigue Moderate-intensity aerobics 3 times a week for at least 12 weeks can significantly reduce cancer-related fatigue both during and after cancer treatment. Adding resistance training can be effective, particularly for patients with prostate cancer.
Health-related quality of life (HRQOL) Moderate-intensity aerobics combined with resistance exercise 2 to 3 times a week for at least 12 weeks can lead to improved HRQOL during and after treatment.
Lymphedema A progressive resistance program focused on large muscle groups 2 to 3 times a week with the caveat of “start low, progress slow” is safe; importantly, the Roundtable stresses that a fitness professional supervise these sessions. There is not enough evidence supporting aerobic exercise in lymphedema to draw conclusions.
Physical function Self-reported physical function can improve with moderate intensity aerobics, resistance training, or both modalities combined 3 times a week for 8 to 12 weeks. Again, supervised exercise is the most effective.
Moderate Evidence of Benefit
Bone health, sleep Exercise may improve bone health and sleep in some situations. However, results of recent research in cancer survivors concluded that evidence of exercise improving bone health and sleep has been inconsistent.
Insufficient Evidence of Benefit
Evidence on the benefits of exercise for several conditions is insufficient. The researchers stress that further research is needed to determine the benefits of exercise on cardiotoxicity, chemotherapy-induced peripheral neuropathy (CIPN), cognitive function, falls, nausea, pain, sexual function, and treatment tolerance.
Moving Through Cancer: Recommendations
The ACSM initiated the “Moving Through Cancer” program to help clinicians worldwide recommend and incorporate exercise into their patients’ prevention and treatment plans. The new recommendations include:
- Exercise is important for all adults for the prevention of cancer, and specifically lowers risk of 7 common types of cancer: colon, breast, endometrial, kidney, bladder, esophagus, and stomach;
- Cancer survivors should incorporate exercise into their day-to-day routine to help improve survival after a diagnosis of breast, colon, or prostate cancer;
- Exercising during and after cancer treatment improves fatigue, anxiety, depression, physical function, and quality of life, and does not exacerbate lymphedema.
- Research that will drive the integration of exercise into the standard of care for cancer needs to continue;
- The increasingly robust evidence base on the positive effects of exercise for cancer patients should be translated into practice.
