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.
Administered by an Interventional Radiologist, each glass bead delivers a highly concentrated dose of radiation that targets the HCC liver tumor via the hepatic artery.
