Prashant Desai, MD, MS
Prashant Desai, MD
Dr. Desai’s clinical interests include breast and thoracic malignancies in addition to IMRT for head and neck, GI, GYN, prostate and  hematologic malignancies. He specializes in Stereotactic radiosurgery(SRS) and  stereotactic body radiotherapy(SBRT) for CNS, Lung, Liver, Spine, Pancreas and Prostate. SRS and SBRT usually involve 1-5 treatments and rely on  three-dimensional imaging and localization techniques to determine the exact coordinates of the target within the body and deliver highly focused gamma-ray or x-ray beams that converge on a tumor or abnormality. Radiation is given with image-guided radiation therapy (IGRT) which uses medical imaging to confirm the location of a tumor immediately before, and in some cases, during the delivery of radiation.
