The lymphatic system consists of a number of structures including the spleen and tonsils, as well as a series of small structures called lymph nodes connected by lymph vessels. Structures of the lymphatic system contain cells called lymphocytes, a type of white blood cell that helps fight off infection. Cancer of the lymphatic system, called lymphoma, develops when lymph cells begin to proliferate uncontrollably, leading to the formation of millions of cancer cells that can travel throughout the body through the lymph vessels. Lymphoma development is associated with a number of symptoms that can help identify the cancer.
Swollen Lymph Nodes
A common symptom of lymphatic cancer is the development of swollen lymph nodes throughout the body. Lymph nodes are small, bean-like structures that house lymphocytes. Lymph nodes are found all throughout the body, including near the skin, but they are generally small enough that they are not noticeable. In lymphatic cancer, the increased number of lymph cells leads to lymph node swelling and enlargement, which is most noticeable as a lump in the armpit, on either side of the throat or in the groin, according to the University of Maryland Medical Center. Long-term lymph node swelling that cannot be explained by disease or infection may indicate the presence of lymphatic cancer, and requires medical attention.
Pain
Another symptom associated with lymphoma is pain, particularly in the abdomen, according to the Leukemia and Lymphoma Society. The abdominal cavity contains a number of lymph nodes, which enlarge and swelling during lymphoma development. As the lymph nodes grow, they begin to press against other structures within the abdomen, leading to aches and pains. The pain may present as rapid-onset, acute pain or prolonged chronic pain, and may interfere with the patient's day to day life. Pain as a result of lymphoma development can be treated with medication to increase the patient's quality of life during cancer treatment.
Night Sweats
Another symptom of lymphoma is the development of drenching and prolonged night sweating. Lymphomation.org indicates that night sweats may develop since the development of lymphoma can mimic the body's response to disease, and the activation of the immune system can lead to fever and excessive sweating. Night sweats can develop as a result of other factors, such as infection or dietary choices, but long-term excessive night sweats may indicate lymphoma. Patients experiencing night sweats for weeks or months should seek medical attention to address the possibility of lymphoma.
