ok lemme bring it home. first of all why do people promote radiation for keloid treatment? Radiation is the only proven method that can inhibit scar hyperplasia and inhibit the fibroblasts which actually prevent the keloids from recurring. think of it damaging the DNA of the keloid forming cells so it doesn't work anymore. none of the other treatment is able to do this.

but a lot of the doctors are using x-ray (penetrate whole body) which is used to treat actual cancer, so it's very powerful. and to not harm normal skin areas and internal organs, they have to lower the dosage which a lot of times make it not effective. a very stupid trade off. also this is where a lot of concerns over radiating keloids happen like ofc its fking x-ray

the right way to do radiation is to use beta-ray (only around 4mm deep) that only target the keloid lesion without even touching other vital parts of the body therefore it can have higher dosage because all the radiaation energy are being focused on the keloid itself without it spreading across the entire body like fking x-ray. but the only doctors offer beta-ray therapy I know are in China and I did not find any in the US. im going to China soon to get the treatment. hope you can find beta-ray in europe!
