Hematology

Hematology is the branch of medicine that deals with blood and disorders of the blood. In many hospitals hematology and oncology are combined into one department. Oncology is the medical specialty that focuses on diagnosing and treating cancer. The two are a natural pairing because some of the most severe blood disorders are cancers. These include lymphoma and leukemia.

Physicians who specialize in hematology are called hematologists. Because the two fields are so closely related, hematologists may dual-specialize in hematology and oncology. Hematologist are skilled in the diagnosis, treatment and prevention of disorders of the blood and lymphic system. Major conditions that fall under the specialty of hematology include anemia, bleeding disorders, clotting disorders, leukemia, lymphoma and platelet disorders. Patients with genetic blood disorders, such as Sickle Cell Anemia are also treated by hematologists.

Blood is made up of three components. Red blood cells carry oxygen, white blood cells fight infection and platelets help the blood to clot. If has very high or very low levels of any of these components in the blood, that person may have a blood disorder.

For example, anemia is a condition caused when a person has too few red blood cells, which causes an iron deficiency that makes the patient feel weak and tired. Though anemia can occur on its own, it may also be a sign of a more serious disorder. Hematologists utilize a range of techniques to diagnose and treat disorders of the blood. Severe blood disorders can sometimes be cured or treated using blood transfusions or bone marrow transplants.

Chemotherapy, a common cancer treatment, is often administered in the hematology/oncology department. During this treatment, cancer killing drugs are introduced into the body, most commonly in the form of a pill, injection or IV. They spread through the body via the blood stream.
