Texas A&M used this technique to treat osteosarcoma (bone cancer) in a dog for whom amputation was not an option.
What I like about this idea is that it is highly targeted and precise.
Instead of external radiation, the radiation is delivered directly into the tumor, which reduces exposure of healthy tissue. This technique also allows for higher doses of localized radiation than a typical radiation treatment.
I think that this makes it more effective option, likely with fewer negative effects.
