Physical activity linked to reduced cancer risk and improved survival

Recent research indicates that physical activity can reduce cancer risk and help prevent recurrence following treatment. A clinical trial involving over 1,700 colorectal cancer patients demonstrated that those participating in a three-year exercise program had a lower likelihood of disease recurrence and higher survival rates.

Experts suggest that exercise increases the activity of immune cells that fight cancer. Additionally, data from the University of Texas MD Anderson Cancer Center indicates that physical activity can lower inflammation and insulin levels, both of which are linked to certain types of cancer.

Beyond physical benefits, exercise during treatment has been shown to alleviate fatigue, anxiety, and depression while improving quality of life and physical function. It may also mitigate “chemo brain”—the cognitive difficulties experienced during chemotherapy—by improving blood flow and supporting learning and memory processes. Experts recommend approximately 30 minutes of daily activity, including strength and aerobic exercises, noting that low-intensity activities like walking or yoga can also provide significant benefits.
