Hodgkin's lymphoma /

Hodgkin's lymphoma, previously known as Hodgkin's disease, is a type of lymphoma, which is a cancer originating from white blood cells called lymphocytes. It was named after Thomas Hodgkin, who first described abnormalities in the lymph system in 1832. Hodgkin's lymphoma is characterized by the orderly spread of disease from one lymph node group to another and by the development of systemic symptoms with advanced disease. When Hodgkins cells are examined microscopically, multinucleated Reed-Sternberg cells (RS cells) are the characteristic histopathologic finding. Hodgkin's lymphoma may be treated with radiation therapy, chemotherapy or hematopoietic stem cell transplantation, the choice of treatment depending on the age and sex of the patient and the stage, bulk and histological subtype of the disease. The disease occurrence shows two peaks: the first in young adulthood (age 15–35) and the second in those over 55 years old. The 10-year overall survival rate is more than 90% for any stages, early stage may help more (stage I or II) Hodgkin's lymphoma. Since many patients are young, they often live 40 years or more after treatment. However, few studies follow patients as long as 25
