It is simply impossible to completely cure cancer by relying on running alone. Running can enhance the resistance of the body and stimulate the anti-tumor immune response of the body. It is conducive to the recovery and prevention of recurrence of tumor patients, and prolongs the disease-free survival period of patients. However, malignant tumors are formed due to gene mutations caused by various reasons, causing malignant transformation of normal cells and unrestricted growth. In early malignant tumors, even though running can stimulate the body’s anti-tumor immune response, regular treatment without combining other major anti-tumor treatments such as surgery and chemotherapy cannot control the growth of cancer cells. Let alone removing cancer cells and curing cancer. Running and other physical exercise measures, although conducive to tumor treatment, can only be used as an auxiliary means, not as the main or even the only treatment method.
