Why does working out reduces chances of getting cancer?

Question

Cancer occurs when cell splitting, for growth or regeneration, doesn’t happen correctly. So more cell regeneration means higher probability of getting cancer.

Now when you workout you are growing a muscle meaning you are creating new cells which in turn creates higher probability of getting cancer.

So why do we say working out/ active lifestyle reduces cancer chances?

Answer 1

The way I understand it, in basic terms, is that our bodies are built to be stressed, and that cellular processes when under stress engage in activities that suppress the mechanisms that allow cancer to grow. Like endurance cardio work in older people, long-term endurance exercise training may provide a protective effect on muscle telomere length in older people.
