Hematologists are medical doctors who specialize in blood related conditions such as leukemia, sickle cell anemia, and hemophilia. Hematology covers the study of blood cells, blood vessels, platelets, clotting, lymph nodes, and bone marrow.
There are many types of blood diseases. There are blood cancers such as leukemia. There are clotting disorders such as hemophilia where blood does not clot enough and deep vein thrombosis where blood clots too much.
Hematologists mainly use blood tests to diagnose diseases. There are blood tests to check white blood cell count, red blood cell count, platelet count, and clotting proteins. Treatments often include prescription medication or supplements. Cancers like leukemia are treated with chemotherapy and radiation.
Leukemia is a broad term for cancers that affect bone marrow or blood. There are many different specific types of leukemia such as Acute Lymphoblastic Leukemia and Acute Myeloid Leukemia. The type depends on where it is and what cells it affects such as red blood cells, white blood cells, bone marrow, or lymphocytes. Some types are more common and treatable. Others are rare and aggressive.
