Pronounced RAY-dee-oh-EM-boh-lih-ZAY-shun, it is a type of radiation therapy used to treat liver cancer or cancer that has spread to the liver.
How is it performed?[edit | edit source]
A thin, flexible tube is used to inject tiny beads that hold the radioactive substance yttrium Y 90 into the main blood vessel that carries blood to the liver.
Mechanism of action[edit | edit source]
The beads collect in the tumor and in blood vessels near the tumor, and the yttrium Y 90 gives off radiation. This destroys the blood vessels that the tumor needs to grow and kills the cancer cells.
Type of internal radiation therapy[edit | edit source]
