Radiation therapy uses high-energy rays to kill myeloma cells. A machine called a linear accelerator or linac delivers beam radiation to targeted area(s) of your body while you lie on a moveable table. Parts of your body not affected by myeloma, like the reproductive organs, are shielded to help reduce the treatment's side effects. The procedure itself is painless, though some people may feel uncomfortable remaining in the same position for several minutes during the session.
Radiation therapy is used:
- To treat patients with a single mass of myeloma called a plasmacytoma
- For some carefully selected patients whose bone pain doesn't respond to chemotherapy
