What is an example of a primary malignant disorder of the blood?

• A. Anemia
• B. Leukemia
• C. Thrombocytopenia
• D. Hemophilia

Answer: (B)

Leukemia is classified as a primary malignant disorder of the blood because it originates in the bone marrow, where blood cells are produced. This cancer primarily affects white blood cells, leading to an overproduction of these cells that can interfere with normal blood function. In leukemia, the malignant cells proliferate uncontrollably, resulting in various forms of the disease, such as acute or chronic leukemia, which varies based on the type of blood cell involved and the speed of disease progression. In contrast, the other options represent different health conditions. Anemia is characterized by a deficiency in the number or quality of red blood cells, leading to reduced oxygen transport but is not malignant. Thrombocytopenia is a condition marked by low platelet counts which can lead to bleeding but doesn't involve a direct malignancy either. Hemophilia is a genetic disorder affecting blood clotting due to deficiencies in clotting factors, and it is not a malignant disorder. Thus, leukemia stands out as the only primary malignant disorder of the options provided.
