Summary

A study published in Cancer finds regular exercise significantly boosts survival rates among colon cancer survivors.

Patients who exercised the equivalent of walking an hour daily, six days a week, lived longer — sometimes outliving peers who never had cancer.

Even those with recurrent cancer benefited. Researchers surveyed nearly 3,000 survivors and linked physical activity to reduced inflammation, improved immune function, and lower insulin levels.

Experts stress exercise is one of the most effective modifiable factors for both prevention and survival, especially amid rising colorectal cancer rates in younger adults.
