The William E. Kahlert Regional Cancer Center physicians also specialize in hematology, which is the field of medicine concerning the blood and the generation of blood in the bone marrow.

Hematology studies the red and white blood cells, their relative proportions and general cell health, and the diseases that are caused by imbalances between them, notably anemias, coagulation disorders and immune deficiencies. Hematology is a distinct subspecialty of internal medicine, separate from but overlapping with the subspecialty of medical oncology.
