Prevent dangerous adverse effects with our y 90 safety guide. Learn the vital risks and amazing ways to stay healthy during care.

What is Yttrium-90 (Y-90) Radioembolization?

Y-90 radioembolization is a non-invasive treatment. It uses radioactive beads to target liver tumors through the blood. An interventional radiologist performs this procedure.

How the Procedure Works

In the Y-90 procedure, tiny beads with Y-90 are injected into the liver’s blood supply. These beads release beta radiation. This radiation kills the tumor cells without harming the healthy liver tissue.

Common Conditions Treated with Y-90

Y-90 radioembolization treats several liver conditions, including:

• Hepatocellular carcinoma (HCC)
• Metastatic colorectal cancer
• Other metastatic diseases to the liver

This treatment is great for those who can’t have surgery or other treatments.
