New Research Identifies the Key Reason Exercise Lowers Cancer Risk
How Exercise May Reduce Cancer Risk Through a Powerful Metabolic Shift A growing body of scientific evidence indicates that regular physical activity plays an important role in lowering cancer risk. While this connection has been observed for years, new research using animal models suggests a possible explanation for how exercise may influence tumor growth. Recent findings from controlled mouse studies show that physical activity may trigger a metabolic shift inside the body. This shift appears to provide muscle cells with more fuel to burn while simultaneously limiting the amount of energy available for cancer cells. As a result, tumors may struggle to grow as efficiently. In these studies, mice with breast cancer or melanoma tumors were divided into groups based on different diet and exercise routines. Researchers used molecular tracers to observe how glucose was metabolized throughout the body. The active mice were found to reroute glucose toward their muscles, reducing the amo...
