Since radiation therapy and chemo extend life and quality for some cancers its an easy sell to use it on other types of cancer by using a salespitch that hides the fact that chemo and radiation has not been proven to work for soft tissue sarcoma in humans or cats. Promotion of unproven medical care in the market place is a healthfraud practice. Doctors must be made to communicate in witting, when they take your money, what treatments have been proven to work. If I had a cat that had surgical removal of VAS with clean margins and the vet then did radiation on the area without telling me radiation has been shown to cause the very cancer he just removed and the cancer came back I would find a lawyer.
