Dr. Aaron P. Mitchell

Dr. Aaron P. Mitchell, MD, MPH, is a medical oncologist at Memorial Sloan Kettering Cancer Center specializing in the care of patients with prostate cancer and bladder cancer. He holds a dual appointment in MSK's Department of Epidemiology and Biostatistics, reflecting his combined focus on direct patient care and population-level cancer research. Dr. Mitchell grounds his clinical practice in two core principles: patient autonomy and evidence-based medicine. In his view, the physician's role is to provide thorough information, guidance, and counseling, while the patient retains full authority over all treatment decisions, a commitment he upholds with consistent respect for each individual's choices.

Dr. Mitchell's research examines cancer at the population level, with a particular interest in healthcare policy and how systemic improvements can enhance treatment and patient experiences across oncology. His work within the Department of Epidemiology and Biostatistics positions him at the intersection of clinical medicine and public health, allowing him to evaluate and address broader gaps in how the healthcare system serves people with cancer. He is committed to evidence-based recommendations, drawing on treatments validated through rigorous clinical trial testing, and actively involves his patients in trials of emerging therapies that will shape the next generation of proven treatments.

At the heart of Dr. Mitchell's approach is a deep respect for the individuals he cares for, guided by the belief that informed patients who are supported, not directed, are best equipped to navigate their cancer journey. His dual role as a treating oncologist and health systems researcher allows him to bridge the gap between what happens in the clinic and what can be improved at the policy level. Through this integrated approach, Dr. Mitchell works to advance both the science of cancer care and the human experience of receiving it.
