What this means
Leukemia is cancer of blood cells that starts in blood-forming tissue such as bone marrow.[1]
What people may notice
- Bone marrow makes cells that develop into white blood cells, red blood cells, and platelets.[1]
- Leukemia type depends on which blood cell becomes cancer and whether growth is fast or slow.[1]
- Blood count tests can be part of diagnosis and monitoring context, but CBC is not a cancer diagnosis by itself.[1,2]
Key variables
White-cell context matters, but leukemia classification is not just a WBC number.[1,2]
Leukemia begins in blood-forming tissue and can disrupt normal cell production.[1]
Red-cell production can be affected when marrow is crowded or abnormal.[1,2]
