Lutetium 177 therapy, also known as Lu-177 therapy, is a type of targeted radionuclide therapy used in the treatment of certain types of cancer. This therapy involves the use of the radioactive isotope Lutetium-177, which emits beta radiation to target and destroy cancer cells. The treatment is often combined with a molecule that specifically binds to cancer cells, ensuring that the radioactive material is delivered precisely where it is needed.
