MEDICAL PHYSIOLOGY

Detailed explanation-1: -Leukemia usually involves the white blood cells. Your white blood cells are potent infection fighters-they normally grow and divide in an orderly way, as your body needs them. But in people with leukemia, the bone marrow produces an excessive amount of abnormal white blood cells, which don’t function properly.

Detailed explanation-2: -At the time of diagnosis, patients can have very, very high white blood cell counts. Typically a healthy person has a white blood cell count of about 4, 000-11, 000. Patients with acute or even chronic leukemia may come in with a white blood cell count up into the 100, 000-400, 000 range.

Detailed explanation-3: -In patients with leukemia, the bone marrow produces abnormal white blood cells. These abnormal cells do not work the same way as healthy white blood cells. Instead, they grow and divide uncontrollably, crowding out and replacing normal cells.
