Non-Hodgkin’s lymphoma is cancer that originates in the lymphatic system and spread throughout the body. In non-Hodgkin’s lymphoma, tumors develop from lymphocytes – a type of white blood cell.
Non-Hodgkin’s lymphoma is more common than the Hodgkin lymphoma.
The primary difference between Hodgkin’s and non-Hodgkin’s lymphoma is in the specific lymphocyte each involves.
If the examination of cancer cells under a microscope gives the presence of Reed-Sternberg cell (a specific type of abnormal cell) then the lymphoma is known to be Hodgkin’s lymphoma and in absence of Reed-Sternberg cell, the lymphoma is classified as non-Hodgkin’s Lymphoma
