Haemotological malignancy

Patent Pending Tumors of the hematopoietic and lymphoid tissues or haematopoietic and lymphoid malignancies are tumors that affect blood, bone marrow, and lymph nodes.[1][2] As the three are intimately connected through the immune system, a disease affecting one of the three will often affect the others as well: although lymphoma is a disease of the lymph nodes, it often spreads to the bone marrow, affecting the blood and occasionally producing a paraprotein.
