Experts don't know what causes non-Hodgkin's lymphoma (NHL).
When a person has non-Hodgkin's lymphoma, abnormal rapid cell growth occurs. This abnormal growth may need a "trigger" to start, such as an infection or exposure to something in your environment. There is also a link between NHL and problems with the Reference immune system Opens New Window.
NHL is not contagious and is not caused by injury.
