Total Body Irradiation (TBI)
Total Body Irradiation (TBI) is a form of radiation therapy used primarily as part of the conditioning regimen for bone marrow or stem cell transplant patients. TBI involves delivering uniform doses of radiation to the entire body to eliminate cancer cells and suppress the immune system, reducing the risk of transplant rejection. This treatment is crucial for patients with certain blood cancers, such as leukemia and lymphoma. Administered by a specialized team of radiation oncologists and medical physicists, TBI is carefully planned to balance effective cancer treatment with the protection of vital organs. Though it can have significant side effects, TBI is a powerful tool in preparing the body for successful transplantation, offering hope for remission and long-term recovery.
