Researchers here note that undertaking strength training and aerobic exercise acts to reduce mortality due to cancer, to a similar degree as these activities are known to reduce all cause mortality in later life. The mechanisms involved are likely diverse, but it is worth noting that (a) muscle tissue is metabolically active in beneficial ways, such that more muscle is better than less muscle, (b) better immune function is linked to exercise, and immune surveillance is critical to cancer prevention, and (c) exercise helps to reduce chronic inflammation, where chronic inflammation helps to drive the establishment and development of tumors.
Regular muscle strengthening exercises associated with aerobic activities can reduce cancer mortality, according to a systematic review of epidemiological studies. Workouts with squats, rowing, planks, weight training and so on can reduce the probability of dying from cancer by 14%. When these exercises are combined with aerobic activities, the benefit is even greater, potentially reducing mortality by 28%.
