Which of the following statements about Acute Lymphoblastic Leukemia (ALL) is true?

Acute Lymphoblastic Leukemia (ALL) is characterized by an increase in the production of immature lymphocytes, which can disrupt normal blood cell production. This disruption often leads to a deficiency in platelets (thrombocytopenia), resulting in increased bleeding and bruising. Patients with ALL may experience easy bruising, frequent nosebleeds, and other signs of bleeding due to the reduced ability of their blood to clot effectively.

In contrast, the other statements do not accurately reflect the characteristics of ALL. It is more prevalent in children than in adults, making the claim that it primarily affects adults inaccurate. The disease is also associated with an increased risk of infections rather than a decrease, as the compromised bone marrow function results in a lower production of white blood cells. Lastly, ALL can frequently involve the central nervous system, and central nervous system involvement is a known complication of the disease. This underscores the importance of recognizing the symptoms associated with ALL and understanding its impact on various bodily systems.
