Total Body Irradiation (TBI)

Total Body Irradiation (TBI) is a medical procedure that delivers a controlled dose of radiation to the entire body. It is often used before a stem cell or bone marrow transplant to destroy cancer cells and suppress the immune system, reducing the risk of transplant rejection. By targeting the entire body uniformly, TBI helps eliminate residual cancer and prepares the body for the new, healthy cells. The process is carefully planned and monitored to minimize side effects, which may include fatigue, skin irritation, and temporary immune suppression.
