Blood is a body fluid which delivers nutrients and oxygen to the cells. It also transports metabolic wastes away from the cells. Any anomaly in the production of blood and its components, such as hemoglobin, bone marrow, platelets, spleen, blood proteins, the mechanism of coagulation, etc. is expressed as a blood disorder. Leukemia, myelodysplastic syndrome, thrombocytosis, polycythemia vera, etc. are some of the disorders of cell proliferation. Coagulation disorders include hemophilia, thrombophilia and coagulopathy. Hematological malignancies are malignant neoplasms affecting the blood, lymph, bone marrow and lymphatic system. These may derive from either the myeloid or lymphoid cell lines. All such disorders are treated in the domain of hematology and oncology. This book contains some path-breaking studies in the fields of hematology and oncology. The topics included herein are of utmost significance and bound to provide incredible insights to readers.
