Non-Hodgkin lymphoma (NHL) is type of cancer that starts in your lymphatic (lymph) system. The lymph system is part of your immune system.
NHL may not cause symptoms right away. Slow-growing lymphoma, also called indolent lymphoma, may not cause symptoms until it grows very large. Aggressive lymphoma grows and spread quickly. It can cause severe symptoms.
When lymphoma does cause symptoms, they can often seem like other health problems at first. This is because NHL can cause many different kinds of symptoms. It depends on where it starts in your body and the kind of lymphoma it is.
Here are some common symptoms of lymphoma:
Swollen, often painless, lymph nodes in the neck, groin, underarm, or above the collarbone
Feeling very tired
Swelling in the belly (abdomen)
Feeling full after eating only a small amount
Upset stomach (nausea), vomiting, or stomach pain
Coughing or trouble breathing
Swelling in your head and arms (called superior vena cava syndrome)
Trouble thinking or moving parts of your body
Itchy, red or purple lumps under the skin
Infections that come back
Abnormal sweating, especially at night
Losing weight without trying
Easy bleeding or bruising
Many of these symptoms are more often caused by other health problems. But it’s important to see your healthcare provider if you have these symptoms. Only a healthcare provider can tell if you have cancer.
