This link goes very indepth about your question: http://www.cancer.org/Cancer/CancerCauses/OtherCarcinogens/MedicalTreatments/radiation-exposure-and-cancer
Basically there are different types of radiation that can be directed specifically at a tumor and not really damage cells around it. Other radiation types are much more damaging and do not treat cancer.
