Radiation oncology allows me to combine my interests in patient care, neuroscience, and medical technology.

Dr. Somu Suppiah is a board-certified radiation oncologist who works closely with medical oncologists, surgeons, other doctors, and the MRO Care Team to carefully develop cancer treatment programs for patients using state-of-the-art radiation therapy protocols. Dr. Suppiah joined MRO in 2018.

Drawing upon his expertise in treating patients who are battling a wide range of cancers, Dr. Suppiah uses his knowledge of MRO’s advanced radiation equipment to achieve the best possible outcomes. Dr. Suppiah has conversational ability in Spanish and Tamil. His technical expertise includes the following technology:

  • External Beam Radiotherapy: Volumetric modulated arc therapy (VMAT), intensity-modulated radiotherapy (IMRT), three-dimensional conformal radiotherapy (3DCRT), Tomotherapy, Orthovoltage.
  • Linac-based Stereotactic Body Radiotherapy (SBRT): Lung, liver, spine
  • Stereotactic Radiosurgery (SRS): Gamma Knife.
  • Brachytherapy: Prostate seed implant (low dose-rate), gynecologic (high dose-rate, MR based), ocular (low dose-rate plaque).
  • Radiopharmaceuticals: Radium-223, Iodine-131.
  • Simulation: CT-based, MR-based. Treatment Planning Systems: MIM, Monaco, XiO, Tomotherapy. Image-Guidance Systems and Motion Management: cone-beam CT, four dimensional CT (4D CT) for gated plans, CT-on-rails.

Dr. Suppiah’s interests include tennis, cycling, coffee, exploring new restaurants, farmer’s markets, orchestra, neuroscience, global health and economics, and current events.
