Radiation therapy for tumors - necessarily malignant?

Not about me, thank God and knocking wood furiously – but was trying to figure out a colleague’s situation. He’s a cancer survivor, and recently told me that he’s had new tumors show up elsewhere in his body a few years later (in the spine, if that makes a difference), and he’ll be undergoing radiation therapy for it. I’m thinking that must necessarily mean that his doctors have a strong suspicion that they’re malignant – otherwise they wouldn’t resort to radiation, would they? Or is that also a standard treatment for benign tumors? Or if it’s none of my business it’s none of my business, I can accept that, but nonetheless I’m concerned. – thanks

About your friend’s situation, I can’t really say, but radiation treatment is used sometimes in the treatment of completely benign tumors such as acoustic neuroma. It may be a preferred treatment to shrink tumors or masses when surgery would cause damage in a delicate area. Situations vary.
