From WikiMD's WELLNESSPEDIA

An injectable formulation of yttrium Y 90 consisting of glass microspheres containing the radioisotope yttrium Y 90.

Mechanism of action[edit]

When injected into the tumor vascular bed, yttrium Y 90 glass microspheres occlude tumor blood vessels and deliver a cytotoxic dose of beta radiation to the tumor site, thereby reducing the tumor burden.
