What is the definition or description of: radioembolization?

Cancer treatment: Radioembolization is a cancer treatment in which radioactive particles are delivered to a tumor through the bloodstream. The particles lodge in the tumor and emit radiation that kills cancer cells. Radioembolization is most often used on cancers in the liver.

Short answer: To be more specific, the microspheres, either glass or resin, are delivered via hepatic artery catheterization during a procedure generally referred to as an angiogram. The safe delivery of these spheres is only performed after a planning study, days prior to the treatment date. It is only offered by centers with experienced interventional radiologists and authorized users.

Radioembolization: Yttrium-90 radioembolization delivers high levels of radiation to hepatic tumors by depositing Y-90 impregnated microspheres directly via the arteries supplying blood to the tumors. This therapy is used to treat both primary & metastatic liver tumors. It's an outpatient, minimally invasive treatment, with less side effects compared to standard cancer treatments. Multidisciplinary approach is Key!
