What is blood cancer?

Leukemia, also known as blood cancer in medical terminology, is a general term for malignant tumors of the hematopoietic system. It encompasses several types, such as acute lymphoblastic leukemia, chronic lymphocytic leukemia, acute myeloid leukemia, and chronic myeloid leukemia. These diseases are characterized by significant changes in white blood cell counts and potentially their distribution. For example, patients with acute leukemia may show the presence of immature and blast white blood cells in peripheral blood, whereas patients with chronic leukemia may exhibit an increased proportion of specific types of white blood cells. Main symptoms of leukemia include fatigue, pallor, lymphadenopathy, bleeding, and infections. Treatment options are varied and include chemotherapy, targeted drug therapy, among others. Please note that prognosis and treatment outcomes may vary depending on individual conditions and disease progression.
