Medical Intelligence & Overview
Acute lymphoblastic leukemia (ALL) is an aggressive form of blood cancer that affects the lymphoid cells in the bone marrow. It's characterized by the rapid growth of immature lymphocytes, which crowd out healthy cells and impair the immune system. Typically affecting children and young adults, ALL requires prompt diagnosis and treatment to improve outcomes. The ICD-10 code C91.0 specifically classifies T-cell and B-cell precursor leukemias, the most common subtypes of ALL.
