Aerobic exercise may reduce the risk of cancer and cancer mortality:
Aerobic Exercise and lung cancer:
Alfano et al. completed a study, drawn from the beta-Carotene and Retinol Efficacy Trial, a lung cancer chemoprevention trial, examining physical activity and lung cancer incidence and mortality among 7,045 (59% male) current and former smokers with a mean age of 63 years. Compared to non-active participants, an increase in physical activity resulted in a 14% decreased risk for all-site cancer among men; a 16% decrease risk for lung cancer and a 15% decrease for cancer mortality was seen among younger participants only. Among women, they reported no association between physical activity and lung cancer incidence. Women who were physically active had a 31% decreased risk of lung cancer mortality compared with women who were not physically active. (3)
