These malignant cells do not function properly, making the patient vulnerable to infections. ALL (Acute Lymphoblastic Leukemia) specifically refers to a neoplastic accumulation of lymphoblasts, which are immature lymphocytes. This type of leukemia is characterized by an overproduction of young, immature lymphocytes.
