External Radiation Therapies : EBRT : Total Body Irradiation
(TBI) Total Body Irradiation (TBI) is an External Beam
Radiotherapy (EBRT) that is often used to prepare the body for
bone marrow transplantation. This radiation treatment therapy
involves applying radiation to most of the body, up to three
times per day, for two to four days. The goal is to suppress the
bone marrow recipient’s immune system, in turn reducing the risk
of rejection and increasing the likelihood that the transplant
will be successful. TBI has the benefit of reaching cancer cells
within scar tissue or other areas of the body that chemotherapy
cannot reach, but the dose of radiation must be low enough that
the body's healthy cells can recover from the treatment. |Body
