What is hematology?

Hematology is the medical specialty focusing on the elements constituting the blood (red and white blood cells, blood platelets, etc.), the lymph and the organs secreting them (bone marrow, spleen, tonsils) as well as related diseases. 

When to see a hematologist?

The abnormal composition of blood appear on the blood test, a standard test. The CBC (blood count) which analyzes the constituents of the blood, their number, their specific characteristics (are they in sufficient number, do they have anomalies) and the SV (sedimentation rate) constitute the pillars. Any decrease or increase in the number and size of each component can be an indicator of a person's state of health. Ongoing treatment or illness can take its toll and alter blood lines. In the event of abnormal blood results and unexplained symptoms (lasting fatigue, anorexia, persistent fever, presence of lymph nodes, etc.), the attending physicianmay need to refer his patient to a hematologist. But not every change is always the sign of a disease. Eating habits, alcohol consumption, or lifestyle habits can affect the size, composition or characteristics of blood elements. After a stay at altitude, red blood cells are more numerous, the blood is better loaded with oxygen and athletic performance can be positively affected.

What does a hematologist treat?

The hematologist works mainly in a hospital environment, but hematology is present in private hospitalization. The hematologist mainly treats disorders of red blood cells (anemia, in deficit; polycythemia, in excess), white blood cells (leukopenia, in deficit; leukemia , in excess), platelets (thrombocytopenia, thrombocytosis, hemophilia, etc.), lymph (lymphomas, multiple myeloma or cancers of the lymphatic system ) or the decrease in the production of blood cells in the bones(Myelosuppression). The bone marrow puncture at the level of the pelvis or the sternum, makes it possible to analyze the quality of the bone marrow. Bone marrow is a tissue that is located in the center of the bones and plays a major role. It makes blood cells (red blood cells, white blood cells and platelets). In addition, examination of the plasma, chromosome and genetic analysis may be necessary. Many hemopathies are serious, and their rapid detection with a simple drop of blood taken is a real asset.
