Total Body Irradiation

Total Body Irradiation (TBI) is a medical procedure that uses precise radiation beams to deliver a uniform dose of radiation to the entire body. It is typically used before a stem cell or bone marrow transplant to destroy cancer cells, eliminate remaining diseased tissue, and suppress the immune system to prevent rejection of the transplanted cells. TBI helps create a clearer environment for the new healthy cells to grow. While effective, it can also affect healthy tissues, so it is carefully planned and monitored by radiation specialists to minimize side effects.
