Evan Z. Lang, MD, MS, is a medical oncologist and hematologist who specializes in general oncology and hematology. He chose a career in oncology after his exposure to cancer research while training in Cleveland.
“I was involved in colorectal cancer research that was leading edge. We studied the formation of tumors and DNA repair genes. What’s amazing is this work played an important role in the development of immunotherapy drugs like Keytruda and Opdivo. I feel as though I have come full circle because at OHC, we participated in the clinical trials that evaluated these drugs, and we have patients who’ve been taking these drugs for several years and are still living and thriving,” said Dr. Lang. “It’s exciting to see the evolution of a treatment, especially when the end results are a new, highly effective treatment for cancer.”
Dr. Lang enhances his clinical knowledge and expertise by being attentive to his patients’ non-clinical needs. His patients consider him to be one of the most caring doctors. “My objective is to provide my patients with up-to-date information and to demonstrate my commitment to excellence, and that includes clinical and emotional support.”
In his free time, Dr. Lang enjoys biking, kayaking and reading.

Patient Reviews
I had total confidence in Dr. Lang and the entire team at OHC. Including myself, I know 3 people that have been cured of cancer, all with different types. GREAT place for treatment. Thank you all. – S.C., May 2022
Dr. Lang and his staff at OHC have done a remarkable job caring for my father for his concerns with his cancer and his situation. Dr. Evan Lang has brought my father a long way in life and we couldn't ask for anything better. We appreciate all that everyone has done for him. I'm proud to say that we are very blessed to have my father around more than was expected so all has been done with great respect to the staff and Dr. Lang. We are very pleased with OHC and the staff. – Anonymous, May 2022
Dr. Lang took time to talk with us and also contacted us promptly with results - he even called during his vacation! – S.H., May 2022
When I went to Dr. Lang I was at my end. He helped me in so many ways and helped me understand my cancer, explained everything, had compassion. All the nurses and receptionists were kind and compassionate. I couldn't ask for better care. I'd recommend Dr. Lang to anyone who is struggling with cancer. – Anonymous, May 2022
