Not an analyze on a very big number of patients (nine):

> Nine patients with late-stage prostate cancer performed 34 minutes of high intensity exercise on a stationary cycle, with blood serum collected immediately before and after, and then again 30 minutes post-workout.

>The team found the serum obtained immediately after this “dose” of exercise contained elevated levels of anti-cancer myokines resulting in suppressed growth of prostate cancer cells in vitro by around 17 per cent.

>Serum myokine levels and cancer suppression returned to baseline after 30 minutes

That doesn't seem very useful, as a layman.

EDIT: we're not talking about the benefits of exercise in general. That's well established and I am in no way questioning that. We're talking about myokines and cancer suppression.

It might have preventative effects on getting cancer in the first place.

So I'm totally talking out of my ass here but there's a variety of things that its important to have happen regularly in your body but not constantly. So even these short doses may have a high net benefit

Being active for half your life protects you from cancer for the rest of it, by that logic. Fitting that to a normal schedule, it makes sense. And points to sedentary life as a cancer permissive style.

How elevated were levels?

Exercising once probably doesn’t help a ton, but if you exercise twice a day or more for decades, it seems like it could be a massive benefit.

And the elevated levels might be prolonged in those who exercise regularly, just like a lot of things are improved only slightly by one bout of exercise but vastly improved by years of regular exercise

But think of all the exercise pills I can sell. That's useful to my wallet.

I am totally not dismissing the value of exercise but when my father had a high PSA he was advised to stop riding his bicycle for three weeks because it could give false high readings.

That is specifically due to the pressure on the prostate from the bicycle seat though I think. No one will tell you to stop riding a bike for any other cancer generally that I am aware of. Plus assuming keeping all treatment, avenues open, surgical processes and seed, therapy or brachy therapy would be going through some sensitive bits, i.e. the taint. So you don’t want it to be sore already before that I would think.

Yeah this is specific to biking! Not activity in general.
