Proven tumor control
TheraSphere is the first and only FDA approved transarterial radiation therapy for hepatocellular carcinoma (HCC), delivering maximum damage to the tumor, sparing healthy tissue, and preserving treatment options.
How TheraSphere works
TheraSphere is a treatment consisting of millions of tiny glass beads — each thinner than a strand of hair — containing radioactive Yttrium-90. An Interventional Radiologist administers TheraSphere through a microcatheter typically placed in the femoral artery. Each glass bead delivers a highly concentrated dose of radiation that targets the tumor via the hepatic artery.
