Patient Reviews Request Appointment
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.
