Exercise In Colon Cancer Modulation: An Experimental Approach, Marcelo M. P. Demarzo, Sérgio B. Garcia, Sérgio E. A. Perez

International Journal of Exercise Science: Conference Proceedings

Carcinogenesis is a complex process best characterized as an accumulation of alterations in genes regulating cellular homeostasis. The whole process can be divided into three main stages: initiation, promotion, and progression. It has been observed that moderate and regular physical activity (PA) may prevent cancer, mainly colon cancer (CC), up to 50% in humans. The evidence that PA protects against colon cancer is convincing. Also, PA probably protects against postmenopausal breast cancer and cancer of the endometrium. On the other hand, exhaustive exercise increases free radical DNA oxidative damage, inflammation and depresses immune function, events also related to the increased …
