Hodgkin's Lymphoma is a type of cancer that originates in the lymphatic system, which is part of the body's immune system. It specifically affects a type of white blood cell called lymphocytes. This cancer is characterized by the presence of a specific type of cell known as Reed-Sternberg cells, which can be identified under a microscope. Symptoms of Hodgkin's Lymphoma may include swollen lymph nodes, fever, night sweats, and unexplained weight loss. The exact cause of this disease is not fully understood, but it can occur in people of any age, with a higher incidence in young adults and those over 55. Treatment options often include chemotherapy, radiation therapy, or stem cell transplant.
