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?

It doesn’t!

We don’t!
First off: working out does not mean growing new cells. It means improving the “health” and increasing the size of existing muscle cells.
Second: physical activity is something our bodies were largely designed around incorporating into our normal lives. Doing so helps overall improve your health as opposed to being relatively stationary, and very notably, it also helps regulate and balance your natural hormones. Cancers have many origins, but hormones are often a key factor in their development.
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.
Working out improve blood flow = more immune cells patrolling the body.
Working out to improve oxygenation, cancer cells despise high oxygen environments because it inhibits angiogenesis (development of new blood vessels where it can spread)
You get a lot of tumor cells that your immune system just deals with and they never turn into cancer. Working out improves your immune system.
I assume you men working out and not working out. Unfortunately there is no direct correlation between the two because this who do not work out will be highly likely to have different lifestyle choices – environment, hobbies, smoking, alcohol, diet, amount of exercise, weight et al. All lifestyle choices will have physiological effects, e.g. being vegan you are forced to take supplements to avoid really nasty things happening to you, some are “good” and some are “bad”.
someone who works out is likely, although not necessarily so, to consume more “good” than “bad”
