Exercise helps ease cancer treatment side effects and supports better overall recovery.
Cancer treatment can take a big toll on the body and mind. People often deal with lasting side effects, like tiredness, foggy thinking, nerve pain, or heart problems, even after treatment ends. A recent look at dozens of studies shows that regular physical activity can help ease some of these problems, and in some cases, prevent them altogether. The research covered many kinds of cancer and types of exercise. The findings were fairly consistent: staying active during and after treatment makes a real difference.
The researchers pulled together results from 80 different studies involving people with various kinds of cancer, including breast, prostate, lung, and blood cancers. They examined nearly 500 links between exercise and how it affects the body and mind. More than half of those showed positive effects, and nearly one out of every five results was backed by strong evidence.
The types of exercise people did ranged widely. Some did slow, focused movement like tai chi, yoga, or Qigong. Others walked, lifted weights, or did short bursts of high-intensity training. Even light movement helped in some cases. People who exercised experienced less damage to their heart and nerves from chemotherapy. They also reported fewer issues with memory and focus, sometimes known as “chemo brain.”
Exercise helped with other problems too. It made sleep better, reduced pain, and helped improve mood. People felt more capable of doing everyday tasks. They connected better with others and said their quality of life improved. In short, being active didn’t just help the body—it helped the whole person feel better.
The benefits didn’t stop there. Some people who exercised before surgery had fewer problems afterward. They stayed in the hospital for shorter periods of time and bounced back more quickly. In some cases, their risk of dying from complications went down. Certain blood markers that can indicate inflammation or hormone imbalances also improved with exercise. These changes can be important for long-term recovery and overall health.
It’s worth noting that people who were able to exercise during treatment may already have been in better shape to begin with. Not everyone with cancer can move around easily. What works for one person might not work for someone else. Cancer type, stage of illness, and the kind of treatment a person receives can all affect what kind of activity is possible. Still, the results suggest that most people can benefit from moving in some way, even if it’s gentle.
Doctors are starting to recommend exercise as part of cancer care, not just as an afterthought. But there’s still work to do. More studies are needed to figure out the best kinds of exercise for different types of cancer. Researchers also want to know how much activity is enough, and when people should start or stop.
For now, though, the message is pretty clear. Movement helps. Whether it’s stretching, walking, dancing, or something more intense, staying active before, during, or after cancer treatment can make a big difference in how people feel and heal.
