What describes the growth rate of acute leukemia?

Acute leukemia is characterized by the rapid proliferation of immature blood cells, commonly referred to as blasts. These cells accumulate in the bone marrow and interfere with normal hematopoiesis, which leads to a quick onset of symptoms. Patients typically experience a fast progression of the disease, often leading to a noticeable decline in health in a matter of weeks to months. This distinguishes acute leukemia from chronic leukemia, which tends to develop more gradually and may go undetected for longer periods. The "fast growing" nature of acute leukemia is critical for diagnosis and treatment decisions, as timely intervention is necessary to improve outcomes.
