But patients who regularly exercise have higher rates of skin cancer than non-exercisers.

It's due to this exposure.

So the American Cancer Society is always reminding where the, you know, the sunscreen and stuff when you go out and cover up during exercise as well because you are potentially putting yourself at higher risk of skin cancer.

Right.

So we just have to be careful about making sure we're giving good evidence on what the benefits are for patients and understanding some of the harms.

And we don't necessarily track all the harms of exercise in these studies, but we now are doing that.

What are some of the adverse events?

What are some of the issues that might be caused by exercise?

Having said that, the benefits of exercise far outweigh the harms of exercise.

But so we don't have to sort of put the harms under the rug to make the case for exercise.

We want to track those.

We want to make sure they're clear.

But what we've demonstrated in cancer is the same thing.

The benefits of exercise for these patients far outweigh any risks to harms.

And we do have to be careful about exacerbating symptoms, making sure patients are exercising within their own capacity.

The other thing I forgot to mention

is the risk with bone metastases.

That's a big concern in the exercise field.

So one of the most popular places for cancer to spread is to the bone.

And these bones can become a bit more brittle.
