In most cases, only one area of nodes swells at a time. When more than one area of lymph nodes is swollen itâs called generalized lymphadenopathy. Some infections (such as strep throat and chicken pox), certain medicines, immune system diseases, and cancers like lymphoma and leukemia can cause this kind of swelling.emoval of one lymph node is called a biopsy. When many lymph nodes are removed, itâs called lymph node sampling or lymph node dissection. When cancer has spread to lymph nodes, thereâs a higher risk that the cancer might come back after surgery.
When the lymph nodes first swell, they might be tender and painful, and they may become larger than their normal pea-size. Other signs and symptoms, depending on the cause of the swollen lymph nodes are sore throat, runny nose, fever, and other indications of an upper respiratory infection.ost causes of swollen lymph nodes are benign, though sometimes the swelling of these lymph nodes may suggest cancer in the head and neck area. There are many causes of swollen lymph nodes, sometimes called âswollen glandsâ (lymphadenitis or lymphadenopathy).
