HEMATOLOGY ONCOLOGY is the research, diagnosis, treatment, and prevention of blood diseases (hematology) and cancer (oncology). It includes problems with your red blood cells,white blood cells, platelets, blood vessels, bone marrow, lymph nodes, spleen, or the proteins involved in bleeding and clotting.
A variety of factors can cause blood disorders. It is not uncommon for those undergoing chemotherapy or radiation treatments to develop a blood disorder in response to the chemicals. Bone marrow illnesses or cancers can cause other blood disorders. The overuse of recreational drugs, chemical exposure, pregnancy complications, viral infections, chromosomal issues, and heredity can often cause or influence blood disorders.
Nearly half of all blood disorders can not be linked to a specific causative factor.
