Exercise is a Powerful Ally in Cancer Prevention and Treatment

Exercise significantly contributes to cancer prevention and treatment by enhancing immune function and inducing stress on cancer cells. It increases the production of immune cells capable of targeting cancer, such as cytotoxic T lymphocytes and natural killer T cells. While cancer cells take years to develop solid tumors, exercise acts as a beneficial stressor, similar to chemotherapy, by elevating inflammatory cytokines and leading to a net anti-inflammatory effect. Normal cells can adapt and produce antioxidants during exercise, whereas cancer cells are unable to adapt, making them more susceptible to stress-induced death. Additionally, the physical forces generated by blood flow during exercise can damage circulating tumor cells, further aiding in cancer cell eradication. Studies indicate that individuals with colorectal or breast cancer who engage in regular exercise experience up to 40% reduced recurrence and a 63% decrease in mortality from cancer, demonstrating a clear link between physical activity and improved cancer outcomes.
