Since I created this site in 2014, more than 15,000 hematologists and oncologists have registered. The feedback has been overwhelmingly positive, and I am honored that so many have used HOQ to prepare for their Hematology/Oncology Board examination.
I wrote all 2,700+ questions and answers myself, aiming for high-yield questions with succinct explanations that work for rapid-fire review before a board examination. They cover Benign Hematology, Malignant Hematology, and Solid Tumors. As of September 2026, all questions have been updated and edited.
Based on the clinical situations I encounter in my clinic, I update the questions to keep them up to date and relevant. As the field of Hematology and Oncology constantly evolves, so will the questions.
These questions should help you prepare for the Medical Oncology and Hematology Board examinations. They also serve as a refresher for those recertifying their boards or preparing for the ASCO in-service exam, and for any hematologist or oncologist who wants to expand their knowledge base.
I hope they will serve as an adjunct to other outstanding resources, including ASH-SAP, ASCO-SEP, the ASCO Question Bank, the MD Anderson and George Washington Board Review Courses, and the NCCN guidelines.

Every HOQ question was developed by hand and aligned with board examination questions using human judgment. The cases are real, drawn from actual patient experiences.
We have never uploaded sample questions to an AI engine to generate similar ones. That would have been the simpler path, but our aim has always been to stay honest and credible for the professionals who rely on this material.
That commitment is why more than 15,000 professionals have trusted us so far, and we are thankful to every one of them.
