The Protective Power of Physical Activity: Insights Into Colon Polyps and Colorectal Cancer

Year: 2025

Type: article

Abstract: Background: Colorectal cancer (CRC) remains one of the most prevalent malignancies worldwide. Regular physical activity (PA) is increasingly recognized as a modifiable factor influencing both cancer prevention and patient outcomes. This review summarizes current evidence on the role of PA in CRC prevention, treatment, and survivorship, emphasizing its clinical significance and underlying biological mechanisms. Methods: A narrative review of recent randomized trials, cohort studies, and meta-analyses published in peer-reviewed journals was conducted. Studies addressing PA in relation to CRC incidence, recurrence, postoperative recovery, and treatment-related outcomes were included. Results: Evidence consistently demonstrates that regular PA reduces the risk of colorectal adenomas and cancer by approximately 20–30%. In CRC survivors, structured exercise programs improve physical and psychological well-being, mitigate treatment-related side effects, and may decrease recurrence and mortality risk. Randomized trials such as CHALLENGE and PHYSSURG-C highlight that supervision, intensity, and duration are critical for achieving clinical benefits. The beneficial effects of PA are mediated by metabolic, inflammatory, and immune pathways, including improved insulin sensitivity, reduced systemic inflammation, and enhanced immune function. Conclusions: Regular physical activity should be considered as a component of colorectal cancer prevention and survivorship care, offering measurable benefits for both clinical outcomes and quality of life.
