Fill in the blank(s) with the appropriate word(s).
An active lifestyle has been shown to have a protective effect against cancer. Physical fitness and cancer mortality in men and women may have a graded and consistent inverse relationship. Physical activity seems to work through a variety of mechanisms to protect against cancer. Growing evidence suggests that moderate exercise improves the autoimmune system, which may play a role in preventing cancer. Exercise releases epinephrine, which helps "natural killer cells" circulate in tumors. Physical activity also reduces insulin and leptin levels.
