A hematologist-oncologist is a physician who specializes in the diagnosis, treatment and/or prevention of blood diseases and cancers such as iron-deficiency anemia, hemophilia, sickle-cell disease, leukemia and lymphoma. This physician is trained in hematology the study of blood and oncology the study of cancer.
Hematologist-oncologists do not usually treat operable cancers such as prostate cancer, but specialize in treating blood cancers, such as Hodgkins and non-Hodgkins lymphomas, leukemias and multiple myelomas. A hematologist-oncologist may also specialize in the management of solid tumors.
Hematologists focus largely on lymphatic organs and bone marrow and may diagnose blood count irregularities or platelet irregularities. Hematologists treat organs that are fed by blood cells, including the lymph nodes, spleen, thymus and lymphoid tissue.
Although hematologists work together with experts from various medical and surgical specialties, hematology is most often linked with oncology. Hematologists and oncologists work together to care for adults and children with cancers of the blood and bone marrow, including leukemia and lymphoma.
