Which term means a malignant tumor composed of cells derived from hemopoietic tissues of the bone marrow?

Haematopoietic and lymphoid malignancies are tumors that affect the blood, bone marrow and lymphatic system and all of those elements are very closely connected. Because of the connection between the circulatory and immune system, if one of the elements is affected it is very possible that the other will be affected too. Type of hematological malignancy includes:
1. Leukemias-cancers of white blood cells which usually begin in the bone marrow
2. Lymphomas-blood cancers developed from the lymphocytes
3. Myelomas-cancer of plasma cells (which produce antibodies).
