Which term best matches the following definition: A progressive disease in which the bone marrow produces an increased number of immature or abnormal white cells?

• A. Leukemia
• B. Myocardial Infarction
• C. Rheumatoid Arthritis
• D. Emphysema

Answer: (A)

Leukemia fits this description. It’s a cancer of the blood-forming tissues, including the bone marrow, where white blood cells begin growing uncontrollably and often remain immature. This leads to an overproduction of abnormal white cells that don’t function properly and crowd out healthy blood cells, causing infections, fatigue from anemia, and increased bleeding or bruising due to low platelets. The other conditions affect the heart, joints, or lungs and do not involve the bone marrow producing an abnormal, excessive number of immature white cells, so they don’t match the definition.
