What is AML?
Neoplastic proliferation of immature blast cells unable to differentiate to mature neutrophils resulting in bone marrow failure
What does AML lead to?

General anaemia

What is CML?
- Uncontrolled proliferation of myeloid cells
- Most cases are due to a reciprocal translocation of 9;22 of the Philadelphia chromosome which increases tyrosine kinase
