Hematologic malignancies are a group of cancers that affect the blood, bone marrow, and lymph nodes. These cancers arise from abnormal growth of cells in the blood-forming tissues, such as leukemias, lymphomas, and multiple myeloma. Hematologic malignancies can disrupt the production and function of blood cells, leading to symptoms such as anemia, infections, and bleeding disorders. Research in hematologic malignancies focuses on understanding the underlying genetic and molecular mechanisms of these cancers, developing targeted therapies, and improving diagnostic and treatment options for patients. This area of research is crucial for advancing our knowledge of blood cancers and improving outcomes for individuals diagnosed with these diseases.
