How is acute myeloid leukemia different from chronic lymphoma leukemia?

Completely different: Aml- cancer of pregenitor cells in the bone marrow- called myeloid- is a very agressive and life threatening disease. It needs to be treated right away-usually with combination of chemo +/- bone marrow transplant. While, cll is an indolent- slowly progressing cancer of lymphocytes. Does not need to be treated unless it is indicated. Sometimes, one can have cll for years & dies from other cause.

Different cell type: Leukemias typically originate when one of the white blood cell types starts multiplying out of control and preventing the normal cells from doing their job. There are many types of white blood cells and the subtype of leukemia or lymphoma or myeloma depends on which subtype is out of control.
