Dr. Theodore N. Pappas

I am a neurosurgeon and researcher who focuses on surgical solutions for movement disorders and pain due to cancer, prior nerve injury, stroke, failed back surgery, limb amputation, trigeminal neuralgia and other causes. I have always been fascinated by how the brain and spinal cord works, converting a thought in your mind to a physical action or feeling. As a neurosurgeon, I get to treat people who have problems with this process. Every day, I get to help patients make dramatic improvements in their quality of life, which is greatly rewarding. At Duke, we’re lucky to have access to the latest technologies and world-class research. Our technology allows us to perform surgeries in the least invasive, most precise ways possible. When I am not working, I enjoy spending time with my wife and three young boys. Dr. Lad is rated as a Distinguished provider by MediFind in the treatment of Thrombophlebitis.

I am a cancer surgeon who specializes in treating patients with pre-cancerous and cancerous conditions of the pancreas, liver, bile ducts, stomach, and adrenal glands. I initially trained and practiced at Walter Reed Army Medical Center in Washington, D.C. During this time, I served one year on a forward surgical team in Iraq. Following this service, I practiced for 13 years as a surgical oncologist at Memorial Sloan Kettering Cancer Center in New York. In 2018, I joined the faculty at Duke University and now serve as the chief of surgical oncology for Duke Health. I enjoy getting to know my patients and delivering the highest quality of cancer care. I am dedicated not only to treating and curing your cancer, but also providing you with the highest quality of life. Operations for cancers within the abdomen are a serious undertaking, and I am committed to making sure that they are performed with the highest level of expertise.
