You may not notice signs of lymphoma in its early stages. In fact, some lymphomas are found through a chest X-ray or other test done for other reasons.
When lymphoma does cause symptoms, they may be mistaken for infection or problems caused by smoking. For example, some early signs of lymphoma include coughing or shortness of breath, especially while exercising. The signs and symptoms of lymphoma are different, depending on where the disease is in your body. Here are some of the common signs and symptoms of lymphoma:
Swelling (usually painless) in lymph nodes in your neck, groin, underarm, or above your collarbone
Swelling in the abdomen
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
Lymphoma may also cause some symptoms that may indicate the cancer is more likely to grow quickly. These "B symptoms" include:
Unusual sweating, especially at night
Unexplained weight loss
Remember: These symptoms may be caused by lymphoma or by other less serious conditions. It is important to check with a doctor to be sure.
