Hodgkin lymphoma, also known as Hodgkin's disease, is a type of cancer that originates in the lymphatic system, specifically in the white blood cells called lymphocytes. It is characterized by the presence of Reed-Sternberg cells, which are abnormal large lymphocytes. Hodgkin lymphoma primarily affects the lymph nodes, but can also spread to other organs. Research in Hodgkin lymphoma focuses on understanding the causes of the disease, developing new treatments, and improving outcomes for patients. This includes investigating the genetic and environmental factors that may contribute to the development of Hodgkin lymphoma, exploring ways to target and kill cancer cells while minimizing side effects, and finding ways to prevent relapse or resistance to treatment. Overall, research in Hodgkin lymphoma aims to improve diagnosis, treatment, and overall quality of life for patients with this type of cancer.
