The science or study of blood, blood-forming organs, and blood illnesses is known as haematology.
Hematology is the medical discipline that deals with the treatment of blood abnormalities and cancers, such as haemophilia, leukaemia, lymphoma, and sickle-cell anaemia. Hematology is a subspecialty of internal medicine concerned with the physiology, pathophysiology, aetiology, diagnosis, treatment, prognosis, and prevention of blood disorders..
Hematologists are mostly concerned with lymphatic organs and bone marrow, and they may diagnose blood count or platelet anomalies. The lymph nodes, spleen, thymus, and lymphoid tissue are all organs that are fed by blood cells, and haematologists treat them.
