American Board of Internal Medicine Medical Oncology Certification Examination

The American Board of Internal Medicine Medical Oncology Certification Examination is an ABIM subspecialty certification exam for physicians pursuing board certification in medical oncology. It assesses whether candidates can apply the knowledge and clinical judgment needed to care for patients with cancer. Eligibility generally depends on meeting ABIM’s training, certification, and licensure requirements, including completion of qualifying medical oncology fellowship training. Requirements can change, so candidates should confirm their individual eligibility and application steps with ABIM for the 2027–2028 cycle.

Medical oncology exam content spans cancer biology and molecular pathways, risk assessment and prevention, screening, diagnostic workup, staging, pathology, and cancer genetics, alongside the broader clinical management of malignancies. Candidates should expect questions that require applying knowledge to clinical situations, not simply recalling isolated facts. A useful preparation plan follows the current ABIM blueprint, reviews unfamiliar topics systematically, and includes timed question practice with careful analysis of explanations. Use official ABIM materials to verify the exam’s current structure and policies.
