Disease Information

ALL is an aggressive leukemia where immature lymphoid cells (lymphoblasts) multiply rapidly. It's the most common childhood cancer but also occurs in adults. Intensive chemotherapy regimens, often lasting 2-3 years, combined with newer therapies like CAR T-cell therapy have dramatically improved outcomes.

CLL is a slower-growing leukemia affecting mature B-cells that accumulate in blood, bone marrow, and lymph nodes. Many patients may not need treatment for years ("watch and wait"), while others require targeted therapies like BTK inhibitors. Unlike ALL, CLL primarily affects older adults.
