The lymphatic system is a series of tubes or vessels that run throughout your body. It is very like your blood system and works closely with it. It carries a watery clear fluid called lymph. The lymph has a large number of white blood cells called lymphocytes. There are two types of lymphocytes, B-cells and T-cells, and both help to fight infection.
Along the lymph vessels are bean-shaped glands called lymph nodes. The nodes can be felt in some areas of your body. For example, in your armpits, neck and groin. Other nodes cannot be felt so easily and are found in your chest, tummy area and pelvis. Some body organs also form part of your lymphatic system. For example, your tonsils, adenoids, thymus, spleen and bone marrow.

Lymphoma is a cancer of the lymphatic system. Lymphoma cells usually grow in lymph glands (nodes) in your body. This causes the glands to enlarge or swell. Non-Hodgkin lymphoma can start anywhere in your body but the most common place is your neck, armpit or chest. The lymphoma cells can sometimes spread to other lymph glands. They can also enter your bloodstream and spread to other organs. It is also possible for non-Hodgkin lymphoma to start in an organ, such as your liver, stomach or bowel.
There are two types of lymphoma called Hodgkin (HL) and non–Hodgkin lymphoma. The difference between the two types depends on the appearance of the lymphoma cells under the microscope. Most lymphomas are non-Hodgkin in type. In fact, there are more than 50 different types of non-Hodgkin lymphoma.
Non-Hodgkin can be either low grade or high grade in nature. Low grade means that the cells grow very slowly and may need little or no treatment for months or possibly years. The most common types include:
High grade lymphomas grow more quickly. They usually cause symptoms and will need immediate treatment. The most common ones include:
Non-Hodgkin lymphoma affects both men and women. About 600 people were diagnosed with it in Ireland in 2009.
