For people with aggressive B cell non-Hodgkin lymphoma, we commonly recommend a chemotherapy treatment called R-CHOP. It is named after the medicines included in the mixture: rituximab (RituxanÂ®), a monoclonal antibody that helps your immune system destroy the cancer cells and makes the chemotherapy more powerful
Both Hodgkin's lymphoma and non-Hodgkin's lymphoma are lymphomas â a type of cancer that begins in a subset of white blood cells called lymphocytes. Lymphocytes are an integral part of your immune system, which protects you from germs. The main difference between Hodgkin's and non-Hodgkin's lymphoma is in the specific lymphocyte each involves. A doctor can tell the difference between Hodgkin's and non-Hodgkin's lymphoma by examining the cancer cells under a microscope. If in examining the cells, the doctor detects the presence of a specific type of abnormal cell called a Reed-Sternberg cell, the lymphoma is classified as Hodgkin's.
