Total body irradiation (TBI)

We may use total body irradiation (TBI) for patients undergoing a stem cell transplant to treat treatment leukemia, lymphoma and multiple myeloma.

A patient may receive TBI before a stem cell transplant to help the body make room for new, healthy bone marrow cells, and to reduce the potential of the body rejecting the transplant.

TBI is typically given three times a day for several days. The lungs are shielded to lower the risk of damage from the radiation.

Like other types of radiation therapy, TBI is designed to destroy cancer cells. Because it targets the entire body, it may also suppress the immune system and kill diseased bone marrows cells.
