Blood disorders touch every organ system and range from common cytopenias to complex hematologic malignancies and coagulation defects. This book presents a structured approach to anemia, leukemias, lymphomas, myeloproliferative neoplasms, bleeding and thrombotic disorders, and bone-marrow failure syndromes. Practical guidance on interpretation of peripheral smears, flow cytometry, coagulation panels, and marrow biopsy findings is paired with diagnostic algorithms. Therapeutic sections cover transfusion medicine, targeted therapies, chemotherapy regimens, and stem-cell transplantation, with attention to supportive care and infection risk. Chapters on hemostasis and thrombosis include up-to-date anticoagulation strategies and reversal protocols. A concise clinical reference for hematologists, oncologists, and general physicians.
