This is interesting, but we don't usually see any side effects when treating bone mets in the limbs as the surrounding tissue isn't all that radiosensitive. The next study will tell us a lot more.

This proton therapy system isn’t really intended for limbs. It specializes in sensitive areas where you need the radiation dose to penetrate the skin, but not exit the other side of the body. Typical uses are ocular, brain, and prostate.

I suspect that they are just testing this FLASH delivery on less sensitive areas before they blast someone in the head with it.

I was looking in the article to see whether it was a photon or proton based system, since you can do FLASH with both, but I must have missed it. I understand it's not intended for limbs. We already do palliative treatments in one fraction with little to no side effects.
