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
A person with non-Hodgkin lymphoma has abnormal cells in the lymph nodes or spleen that multiply out of control. These cells can form tumors and spread to other parts of the body. The two main types of lymphoma are Hodgkin's disease and non-Hodgkin lymphoma. The exact cause for non-Hodgkin lymphoma is unknown, but gene abnormalities and viral infection may play a role. Non-Hodgkin lymphoma is rare in those under 50 years of age. Roughly 90% of all non-Hodgkin lymphomas are a B cell lymphoma.
