Leukemia is a name for several types of cancer that originate in the bone marrow and cause a large number of abnormal blood cells to form. Which blood cell is this?

Explanation

Leukaemia is a group of blood-related cancers that originate in the bone marrow. In this condition, the number of white blood cells (WBCs) in the blood increases abnormally. WBCs are very important for the body’s immune system, as they protect the body from infections. In leukaemia, the abnormal white blood cells formed are not fully developed, and by crowding out normal blood cell formation, they weaken the body’s immune system.
