Cause

The cause of non-Hodgkin's lymphoma (NHL) is unknown. The incidence of NHL has continued to increase over the years. 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 immune system. NHL is not contagious and is not caused by injury.¹

Symptoms

Symptoms of non-Hodgkin's lymphoma (NHL) depend on the area of the body affected by the disease. The most common symptom is a painless swelling of the lymph nodes in the neck, underarm, or groin. Other symptoms may include:

• Night sweats.
• Extreme fatigue.
• Unexplained weight loss.
• Itchy skin.
• Reddened patches on the skin.
• A cough or shortness of breath.
