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.
If cancer spreads to the lymph nodes it may make them swell up. The swollen lymph nodes are easy to see if they are near the surface of the body â for example, in the neck or under the arm. But if the nodes are deeper in the body, they can only be seen on a scan. Cancer in the lymph nodes may not cause any symptoms. But sometimes, the swollen lymph nodes can block the circulation of tissue fluid. This can cause swelling in the affected part of the body. For example, swollen lymph nodes in the armpit or groin can cause swelling in the arm or leg on the same side of the body.
