The human body has more than 500 lymph nodes connected through a network of lymph vessels. The neck, armpits, groin, abdomen, pelvis and chest have clusters of lymph nodes. These bean-shaped glands produce immune cells and filter impurities from the lymphatic system and bloodstream. It is possible for non-Hodgkin lymphoma to develop anywhere in the body where lymph nodes exist. The disease also may affect organs, such as the liver, stomach and lungs.Early warning signs of non-Hodgkin lymphoma
Because many types of non-Hodgkin lymphoma involve different organs, signs and symptoms may vary depending on the type, location and stage of the disease. Symptoms tend to be fairly non-specific and may share similar characteristics with other illnesses, such as a cold, the flu or a respiratory infection.
One of the most common signs of non-Hodgkin lymphoma is enlargement of one or more of the lymph nodes, which causes a non-painful lump under the skin. Most commonly, this occurs on the side of the neck, under the arm or in the groin region. Sudden and unexplained weight loss is also a common early warning sign of non-Hodgkin lymphoma.
Other common non-Hodgkin lymphoma symptoms include:
When the lymph system detects an infection, lymph nodes produce more immune cells, which may cause them to swell. Swollen lymph nodes, a fever and night sweats may also be symptoms of the cold and flu. However, unlike the cold and flu, non-Hodgkin lymphoma symptoms typically do not go away. If you have symptoms that persist for more than two weeks, or symptoms are recurring and becoming more intense, you should see your doctor.
Sudden and dramatic weight loss, such as losing more than 10 percent of your normal weight in less than six months, is also a sign that deserves medical attention. Sometimes, a patient’s only sign of non-Hodgkin lymphoma is constant fatigue.SVC syndrome
Lymphomas may occur anywhere in the network of lymph vessels throughout the body. Tumors or swollen lymph nodes in the chest area may squeeze the superior vena cava, a major vein feeding into the heart.
When this happens, blood from the head, arms and chest may get backed up and cause swelling, or turn the skin to a bluish-red color. This condition may become severe and require medical treatment, especially if the oxygen supply to the brain becomes restricted.B symptoms
B symptoms are a group of general symptoms that may be indicators of an aggressive lymphoma. B lymphoma symptoms are often identified during the staging process to help determine an overall prognosis and guide treatment decisions.
The staging process generally measures the extent and spread of cancer using the Roman numbers I through IV. The staging of non-Hodgkin lymphoma is unique in that it also assigns the letters A and B to each stage. The letters indicate whether certain symptoms are present.
The letter B indicates that the patient is experiencing one or more of the following symptoms: drenching night sweats, fever or unexplained weight loss. If none of these symptoms has developed, the letter A is used. B symptoms may be signs of a more advanced cancer.Non-Hodgkin lymphoma overview
