The lymphatic system is part of the immune system, the system that defends the body against infection. The lymphatic system is a network of small lymph nodes 
(or lymph glands) connected by very thin lymph vessels, which branch into every part of the body except the brain and spinal cord. The major nodes can be found in the neck, armpits, chest, abdomen, pelvis and groin. Other parts of the lymphatic system include the spleen, thymus and bone marrow.
A clear fluid called lymph flows through the lymph vessels. It contains white blood cells called lymphocytes, special proteins called antibodies, and some waste products. Lymphocytes and antibodies are important parts of your body’s immune system. The lymph fluid passes through the lymph nodes, which filter out bacteria and other harmful agents.
Non-Hodgkin’s lymphoma
Lymphoma is a general term for a cancer that begins in the lymph tissue.
Non-Hodgkin’s lymphoma is a group of cancers of the lymph nodes. These cancers differ in the typed of lymph cells they affect, the symptoms they cause and the speed at which they grow. Sometimes non-Hodgkin’s lymphoma appears at the same time in several parts of the body.
When you have non-Hodgkin’s lymphoma appears are the same time in several parts of the body. When you have non-Hodgkin’s lymphoma, large numbers of abnormal lymphocytes are made.
These abnormal lymphocytes replace some of your normal lymphocytes. This can disrupt your immune system and reduce your ability to fight infections. The lymph nodes also become enlarged, forming painless lumps (tumours).
