Lymphoma - definitionLymphoma - definition
Lymphoma (or malignant lymphoma) – Lymphoma (or malignant lymphoma) – a neoplasm of cells derived from a neoplasm of cells derived from lymphocytes or lymphocyte precursorslymphocytes or lymphocyte precursors
Lymphoma vs lymphoid leukemia:Lymphoma vs lymphoid leukemia: Lymphoma – a neoplasm manifesting Lymphoma – a neoplasm manifesting
primarily as a tumor of lymph nodes or primarily as a tumor of lymph nodes or related organs (e.g. spleen, liver)related organs (e.g. spleen, liver)
Leukemia – proliferation of abnormal Leukemia – proliferation of abnormal cells (lymphocytes or lymphocytes cells (lymphocytes or lymphocytes precursors) in the bone marrow and precursors) in the bone marrow and bloodblood
