Embolization is a treatment in which contrast dye and particles are injected into the hepatic artery through a catheter (thin tube). The particles block the artery, cutting off blood flow to the tumor. Sometimes a small amount of a radioactive substance is attached to the particles. Most of the radiation is trapped near the tumor to kill the cancer cells. This is called radioembolization.
