Hematology and Immunology both involve studies of the immune system. So what’s the difference between these two fields? In this article, we’ll describe some of these key differences.
Let’s start with hematology. This is a field of medicine that involves the study of prognosis and treatment of diseases of the blood. This includes hemophilia and blood cancers such as leukemia and lymphoma. Blood cancers are still cancers, even if they are not solid tumours. For this reason, there is also a significant overlap of hematology with another field of medicine, oncology.
If hematology is a field of medicine involving the study of the immune system, then why is there another field called immunology? Yes, immunology also involves the study of the immune system. However, immunology is a field of biology in all organisms, not just humans. Immunology has important applications in many fields of medicine and creates a foundation for hematology and the emerging field of immuno-oncology. The immune system is a critical biological system that is designed to protect the individual from pathogens, infections, and disease. However, in some cases, the immune system can malfunction. For example, the immune system can start taking signals from a tumour-controlled microenvironment in the case of solid tumours, or by mutations in cells of the immune system itself, as is the case with blood cancers.
So in summary, hematology and immunology are both important fields of study involving the immune system. A key difference is that hematologists are most often physicians, and immunologists are most often scientists. Usually, hematology departments are found in hospitals, whereas immunology departments are found in universities. When immunologists have fully understood the implications of the underlying science of the immune system or diseases related to it, these studies are then available to other scientists in pharmaceutical companies who can develop treatments for these diseases, and then make them available to hematologists, who in turn, can then offer treatment options for patients.
