Hematology

Hematology is the branch of biology. Hematology is the medical field that deals with the treatment of blood disorders and cancers, such as hemophilia, leukemia, lymphoma, and sickle-cell anemia. Hematologists and hematopathologists are medical professionals who specialize in illnesses of the blood and its components.
