There are volumes of evidence associating exercise with reduced risk for breast cancer, but why? We also know that those who exercise after the diagnosis of breast cancer have fewer recurrences, but why? Exact mechanisms have not yet been worked out, but there is new evidence.
Researchers in the US may have found a clue in the body's immune system that maybe part of the answer http://www.sciencecodex.com/exercise_could_fortify_immune_system_against_future_cancers-99993. Exercise fortifies part of the immune system; the T-cells, a special kind of lymphocyte that attacks cancer cells.
They drew blood from cancer survivors, after chemotherapy and then again after a 12 week exercise program of cardio, strength, endurance and balance training. They compared active T-cells to inactive T-cells. At the initial time, there were more inactive T-cells. The 12 week exercise program restored the T-cells to the more active cancer fighting T-cells. They suggest that part of the benefit of exercise (associated with fewer cancers and recurrences) is this restoring the favorable balance of the active T-cells.
Exercise for prevention!
Together we can prevent 86,000 breast cancer cases each year!
