Radioembolization is used to treat primary and metastatic cancer of the liver. This localized treatment only affects the liver and may have milder side effects than other treatments. It may be an option for cancers that are too large to be removed surgically and are not responsive to chemotherapy. 


For this procedure, a doctor sends tiny radioactive beads to tumors through the blood stream, permitting high doses of radiation to be focused directly inside tumors. The goal is to slow the cancer and control disease within the liver. Once the beads are dispersed, they are preferentially taken up by the tumor and release radiation that kills cancer cells. This treatment permits a high dose of radiation to be focused directly inside tumors, while healthy tissue nearby typically receives minimal radiation. Radioembolization has a very short recovery time and in most cases, patients can return home that same day.
