They are part of the lymph system, which carries fluid (lymph fluid), nutrients, and waste material between the body tissues and the bloodstream.
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.
