## TL;DR

Cancer of the blood-forming cells in the bone marrow, which flood the blood with immature or abnormal white cells and crowd out normal blood production. It has no single lump to remove.

## Summary

Leukaemias are classed as acute (fast, immature cells, needs urgent treatment) or chronic (slow, more mature cells), and as myeloid or lymphoid by the cell lineage: AML, ALL, CML and CLL. Because leukaemia cells are accessible in blood and marrow, they were the first cancers to be treated with combination chemotherapy (childhood ALL, 1960s), the first with a targeted drug (imatinib for CML, 2001), the first with CAR-T (ALL, 2017), and the first where measuring residual disease guided therapy. Along with lymphomas and myeloma they form the haematological malignancies, which make up roughly a tenth of all cancers.
