Dr. Lawrence B. Marks

I'm a radiation oncologist, and I specialize in treating brain, base of skull and spine tumors, as well as tumors that arise in the body but go to the brain or the spine, as in certain cases of lung, breast and kidney cancer and melanoma. When I meet with a patient, it’s important for me to introduce them and their family to our team of doctors, therapists, nurses and treatment planners. The patient and their family will also become members of this team – truly the most important part - so we can work together to tailor care based on their wants and needs. At Duke, we’ve developed techniques to precisely and accurately treat small, complex lesions and tumors. We can minimize the amount of radiation that goes into normal tissues and at the same time maximize the amount of radiation where it is needed. Our team is geared to delivering every treatment to each patient exactly as planned, especially in complicated and difficult situations. As a patient or a physician, I think there’s no better place to be than Duke. I love my work, feel honored that my patients place their trust in our team and me and work hard to earn that trust.

I am a radiation oncologist, who specializes in treating head and neck and skin cancers. I chose this career path after watching an amazing friend receive treatment for a voice-box tumor. Her experience inspired me to dedicate my life to helping people like her. The relationships I develop with my patients, their families, and the clinical team are key to clinical success. By educating my patients about their cancers and treatment options, answering questions, and working together to develop a treatment plan, I empower my patients and provide the support they need to get through their treatments. I value being part of a skilled multidisciplinary team focused on providing compassionate and top-notched clinical care. I strive to constantly improve head and neck cancer treatments and am grateful to be able to offer cutting-edge clinical trials options to my patients. Outside of work, I treasure time with my family typically spent in outdoor activities including hiking, biking, camping, backpacking, running, kayaking, skiing, traveling, and playing/watching sports. We enjoy being active in the community and engaging in good causes. Dr. Robbins is rated as an Advanced provider by MediFind in the treatment of Melanoma.
