Hematologic malignancies, which affect the blood, bone marrow, and lymphatic systems, include leukemia, lymphoma, and myeloma. These cancers often present with symptoms like fatigue, swollen lymph nodes, and unexplained weight loss, making early detection challenging. Research is heavily focused on identifying genetic mutations and alterations in the blood that can help in diagnosis, prognosis, and treatment. Advances in stem cell transplantation, CAR-T cell therapy, and novel drug therapies have revolutionized the treatment landscape. Ongoing clinical trials aim to refine these approaches, reduce relapse rates, and improve patient survival rates. Moreover, there is a growing focus on minimizing the long-term side effects of treatments, such as infertility and secondary cancers, which can significantly impact patients' lives.
