SIR-Spheres

SIR-Spheres are a type of treatment used to target liver tumors, particularly those from colorectal cancer. They consist of tiny beads filled with radioactive material. During the procedure, a doctor injects these beads directly into the blood vessels that supply the tumor. The radiation emitted by the beads helps to destroy cancer cells while minimizing damage to surrounding healthy tissue. This targeted approach can help shrink tumors and improve the patient’s quality of life. SIR-Spheres are part of a broader treatment strategy and are often used when surgery is not an option.
