What is yttrium-90 microsphere radioembolization?

Yttrium-90 microsphere radioembolization is used to treat liver cancer. Yttrium-90, a high energy isotope, is embedded on microspheres, which are delivered through a small catheter into the tumor through an artery supplying blood to the tumor. The microspheres become permanently lodged into the tumor, releasing radiation energy into the tumor. This causes tumor destruction, and can spare the normal healthy liver tissue.
