How does radiation therapy treat cholangiocarcinoma?

Radiation therapy uses powerful beams of radiation to destroy tumors. You might receive radiation therapy after surgery to kill any remaining cancer cells. Or your healthcare provider may suggest it before surgery to shrink tumors before removing them. Radiation can also be delivered through transarterial radioembolization (TARE), which uses a catheter to implant tiny beads of radiation (often referred to as “Y90”) in the blood vessels supplying the tumor. The beads block the vessel to prevent blood from getting to the tumor. At the same time, the beads release radiation to shrink the tumor.
