Exercise may be the last thing on a survivor’s mind, but physical activity can actually play an important role in healing.
Doctors aren’t sure why, but physical activity can have several positive effects on breast cancer patients, according to the National Cancer Institute. Not only does research suggest that exercise is safe for many breast cancer patients, but it can improve how your body functions.
Besides increasing your overall state of well-being, exercising after breast cancer treatment has the following benefits:
1. Better outcomes
A large study found that exercising decreases the risk recurrence and progression and increases survival. For example, women who exercised moderately (the equivalent to walking three to five hours a week at an average pace), after a breast cancer diagnosis, experienced a 40-50% reduction in recurrence and death than women who did not.

“One of the most common side effects of breast cancer treatment (surgery, radiation, chemotherapy) is fatigue, which is actually best treated with exercise,” says Jason Ye, MD, a radiation oncologist at the USC Norris Comprehensive Cancer Center of Keck Medicine of USC and assistant professor of clinical radiation oncology at the Keck School of Medicine of USC. “In practice, the more patients become sedentary due to fatigue, the worse the fatigue gets. It’s a vicious circle.”
2. Controlled weight gain
One of the side effects of cancer treatment is weight gain, because many people reduce their physical activity after being diagnosed. On the contrary, keeping both body mass index and body weight in check can increase your chances for survival.
“The link between higher body mass index and worse survival is especially strong in breast cancer,” Ye says.
3. Increased quality of life
Just as exercise before cancer can make you feel better both physically and mentally, it can do the same for you during and after your treatment.
A clinical trial found that cancer survivors who exercised had an increased quality of life, including better sleep, positive body image and improved self-esteem. Another study determined that the positive effects of physical activity increased a patient’s overall quality of life.
“When I see breast cancer patients after surgery, I frequently offer them physical therapy to improve their arm mobility, as they recover from the operation,” Ye says. “At Keck Medicine of USC, our physical therapists are experts in caring for breast cancer patients and can offer a wide range of ways to prevent future complications, such as lymphedema, as well.”
Before undertaking an exercise regime, talk to your doctor to develop a plan that is right for you. If you need additional guidance, work with a physical therapist to strengthen your body. The American Cancer Society offers a recommended list of exercises. Even if you’re an avid exerciser, you don’t want to overexert yourself after cancer treatment.
