They may start in the bone marrow, spleen, thymus or lymph nodes and spread to other parts of the body.
Non-Hodgkin lymphoma is the seventh most common cancer in men and women in the nation. According to the American Cancer Society, about 66,000 new cases of non-Hodgkin lymphoma are diagnosed each year in the United States. Non-Hodgkin lymphoma is slightly more common in white men.
What are the parts of the lymphatic system?
The lymphatic system carries disease-fighting white blood cells throughout the body. It includes:
Lymph: Fluid that carries lymphocytes, a type of white blood cells, through the body in a network of lymph vessels, which are like tiny veins. Lymph helps fight against infection and cancer.
Lymph nodes: Tiny, bean-shaped masses in the underarm, pelvis, neck, abdomen and groin. They filter lymph and store white blood cells to help the body fight disease.
Spleen: An organ on the left side of the abdomen that makes lymphocytes, stores blood cells and gets rid of old blood cells.
Thymus: Located in the chest, this tiny organ stores lymphocytes.
Tonsils: The are nodes in back of throat that produce lymphocytes.
Bone marrow: This is material in bones that produces blood cells.
Non-Hodgkin Lymphoma Types
Non-Hodgkin lymphoma is divided into three types depending on the type of cells in the cancer. These types are:
- B-cell, which makes up 85% of Non-Hodgkin lymphoma cases
Non-Hodgkin lymphoma is classified also by how quickly it spreads.
Low-grade non-Hodgkin lymphoma includes:
- Marginal zone lymphoma
- Mucosa-associated lymphoid tissue (MALT) lymphoma
- Follicular lymphoma
- Mantle cell lymphoma
Intermediate grade non-Hodgkin lymphoma includes:
- Diffuse large cell lymphoma
- Primary mediastinal large cell lymphoma
- Anaplastic large cell lymphoma
High-grade non-Hodgkin lymphoma includes:
- Burkitt’s lymphoma
- Lymphoblastic lymphoma
Relapsed non-Hodgkin lymphoma is disease that comes back after you have received treatment for Non-Hodgkin lymphoma.
Refractory non-Hodgkin lymphoma is new or relapsed disease that does not respond to treatment.
Non-Hodgkin Lymphoma Risk Factors
Anything that increases your chance of getting non-Hodgkin lymphoma is a risk factor. Although scientists don’t know yet what causes non-Hodgkin lymphoma, some factors seem to make you more likely to develop non-Hodgkin lymphoma. These include:
- Gender: Non-Hodgkin lymphoma is slightly more common in men
- Race: Non-Hodgkin lymphoma is slightly more common in Caucasians
- Living in a farming community. Some studies suggest that certain herbicides and pesticides may play a part in lymphoma, but this has not been proven
- Bacteria or viruses, including human immunodeficiency virus (HIV), Epstein-Barr virus (EBV), human T-lymphotropic virus (HTLV) and the bacterium Helicobacter pylori
- Inherited syndromes
Not everyone with risk factors gets non-Hodgkin lymphoma. However, if you have risk factors, you should discuss them with your doctor.

In rare cases, non-Hodgkin lymphoma can be passed down from one generation to the next. Genetic counseling may be right for you. Visit our genetic testing page to learn more.
