@celtic External radiation most often uses photons (x-rays).

However, it was discovered decades ago, that protons (heavy particles) had wavelike characteristics and could be used in applications similar to photons.

The science would indicate that protons should have fewer adverse side-effects than photons in prostate cancer treatment (due to proton’s Bragg-Peak characteristics). But, in recent studies that (fewer adverse side-effects) has not been demonstrated.

If you start off with radiation, you do not get salvaged radiation that is for people that have had a prostatectomy.

I answered your question in another message.

Hey good luck looking around celtic, proton seems good to me. I guess Brian mentioned what it is. I have had 3 cancers, just about all of them there are these quality of life QoL studies. They all have something wrong as they jump to really not the best conclusions, just about always. Things the patients say are one thing as they rave about something online or in discussions or people you meet, another are the studies which sometimes say there are no benefits of anything and all gloom and doom so they go the lowest denominator. So sometimes I think the studies aren't very well done, or not just sometimes, but QoL is hard to gauge so these are hard to determine measurements..

As I was told and found out on my own with proton there aren't many places to get it. The academic ones are booked to the moon, so few slots. As academic doc told me proton treatment in prostate cancer is feast or famine. If you try to get in an academic one, the slots are all taken, that happened to me in 2023 Mayo. But there are private proton centers, sometimes manned by really top people, but they may have few takers as you have to travel there once a week and they are just stand alone centers. If you want some places send me a message and I can reply privately and let you know more about proton places.
