One reason exercise lowers the risk of cancer

Several studies have shown that exercising reduces the risk of cancer. In this regard, there is another study that has found that exercise reduces the risk of cancer.


According to a research team from the University of Colorado in the U.S., people who are active in physical activity, such as sports, are more efficient at handling body byproducts that promote cancerous tumors.

Lactic acid (lactic acid), which makes muscles stiff after exercise, is considered a major driving factor for cancer growth and proliferation, and steady exercise has shown that the body increases its ability to recycle lactic acid as a useful fuel.

The team conducted a study on why exercise reduces cancer based on past research cases based on the Warburg effect of cancer cells actively proliferate in high glucose and low oxygen conditions.

The researchers found that lactic acid interferes with the body's immune response to cancer and helps spread tumors. When exercising, muscles use glucose to produce energy.

However, the body produces lactic acid as a byproduct if there is not enough oxygen to maintain the required amount of energy. Therefore, if oxygen supply improves through steady exercise, it has a recycling system that converts lactic acid into a major fuel for the brain, muscles and organs, which is useful.


The team found that such a system of recirculation could cause cancer cells if it fails. The failure of the recirculation system has been found to be unlikely in athletes, the researchers said, adding that athletes' bodies are used to converting lactic acid into useful fuel.

The findings of this study were published in "Carcogenesis: Lactate production for cannogenesis could be the Purpose and expansion of the Warburg Effect."
