Non-Hodgkin’s lymphoma is a type of cancer that grows in the lymphatic system in the first place. A lymphatic system is a network of tissues, blood vessels, and organs that are supposed to drain fluid from the tissues and makes a part of the body’s germ fighting immune system.

Lymphocytes are primarily white blood cells that grow abnormally and result in tumors, in non-Hodgkin’s lymphoma.

Non-hodgkin’s lymphoma is a type of lymphoma. Lymphoma refers to the cancers of the lymphatic system. There are other subcategories as well, such as diffuse large B-cell lymphoma and follicular lymphoma and even Hodgkin’s lymphoma.

The major difference between Hodgkin’s lymphoma and Non-Hodgkin’s is the existence of cells called reed-Sternberg cells. Both have different treatment responses as well.
