Hematology

Hematology, also spelled hematology (from the Greek αἷμα, haima "blood," and -λoγία), is the branch of medicine concerned with the study, diagnosis, treatment, and prevention of diseases related to blood. Hematology includes the study of etiology. 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, other bleeding disorders and blood cancers such as leukemia, myeloma, and lymphoma. The laboratory work that goes into the study of blood is frequently performed by a medical technologist or medical laboratory scientist. Many hematologists work as hematologist-oncologists, also providing medical treatment for all types of cancer.
