Stereotactic body radiation therapy (SBRT) delivers precise, high doses of radiation to a tumor. SBRT is a specialized technique used to treat tumors in the lung, liver and spine while minimizing damage to the surrounding normal, healthy tissues. It is more of a targeted treatment. We were told that if this procedure wasn’t successful, that SBRT would not be done a 2nd time on the same tumor, due to it’s precision. If it didn’t work the first time, it wouldn’t work the 2nd.
