Hematology is the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood. It involves treating diseases that affect the production of blood and its components, such as blood cells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation. Such diseases might include hemophilia, blood clots (thrombus), other bleeding disorders, and blood cancers such as leukemia, multiple myeloma, and lymphoma.

Oncology is the study of cancer. The field of oncology has three major areas: medical, surgical, and radiation. A medical oncologist treats cancer using chemotherapy or other medications, such as targeted therapy or immunotherapy. A surgical oncologist removes the tumor and nearby tissue during surgery. A radiation oncologist treats cancer using radiation therapy.
