Selective internal radiation therapy (SIRT) is a type of internal radiotherapy used to treat liver tumours that cannot be removed with surgery.;
It may be used to treat:
- cancer that has spread to the liver from the large bowel or other places in the body
- cancer that started in the liver (primary liver cancer).
SIRT is not widely available and is not always funded by the NHS. You may have it as part of a research trial. If your cancer team think it is suitable for you, you may have to travel to a specialist hospital to have it. We have more information about how cancer treatments are made available and what you can do if a treatment is not available.
SIRT uses radioactive beads. It is also called radioembolisation. It is not the same as chemoembolisation (also called TACE or CT-ACE), which uses chemotherapy and sometimes plastic beads.
