Does Deodorant/Antiperspirant Cause Cancer?.What’s The Difference Between Hodgkin and Non-Hodgkin Lymphoma?.An injury such as a cut or bite can also cause nearby nodes to swell because white blood cells accumulate there. For example, when someone has a cold or sore throat, the nodes on either side of the neck, under the jaw, or behind the ears often become enlarged. Swelling of a single group of lymph nodes generally indicates a problem in that particular area. Swollen nodes can occur in one area or in several areas at once. Certain groups of them are located under the skin of the neck, underarms, and groin. During an infection, or if cancer is present, large amounts of this waste material can build up in the nodes, and many kinds of normal immune system cells take up residence there, causing the nodes to swell. There, damaged cells, infectious organisms, and cancer cells are separated out and destroyed. Nodes are situated at key points on the vessels and serve as collection centers. Some of the waste-laden lymph returns to the bloodstream, but the rest enters the lymphatic vessels – tubes that extend throughout the body, much like blood vessels do. It also contains white blood cells, which help fight infections. It performs a variety of roles, including carrying oxygen and other nutrients to cells and carrying away waste products like carbon dioxide. Lymph is a clear fluid that seeps out of the smallest branches of blood vessels and bathes the body’s cells. Lymph nodes are small, bean-shaped tissues that act as filters for lymph. ![]() In a small percentage of cases, though, the swelling can be caused by cancer. Swollen lymph nodes are usually a sign of infection by bacteria or viruses. If, however, a node is an inch or more in diameter, is draining pus, is accompanied by a fever or unexplained weight loss, or remains swollen for an extended period of time such as four to six weeks, you should schedule an examination with your physician.Swollen lymph nodes usually signal an infection or inflammation that will resolve within a short time.Swelling of a single group of lymph nodes generally indicates a problem in that particular area.Lymph nodes exist throughout the body.They might be tender to the touch, which indicates inflammation. Swollen lymph nodes will feel like soft, round bumps, and they may be the size of a pea or a grape. People can check whether their lymph nodes are swollen by gently pressing around the area, such as the side of the neck. What does a swollen lymph node feel like? Lymph nodes that frequently swell are in this area, as well as in your armpits and groin area. Many lymph nodes are located in your head and neck region. Your lymphatic system is a network of organs, vessels and lymph nodes situated throughout your body. Keeping this in consideration, where are the lymph nodes located? ![]() Feel the vertical chain along the upper thigh (see above diagram). Secondly, where is the lymph node in the groin located? Diagram of the lymph nodes in the groinThere are two areas to look for inguinal ( groin) nodes: Feel the horizontal chain of nodes in the right groin just below the ligament (see above diagram). From there, lymph fluid drains into other lymph nodes in the pelvis. These nodes drain into three to five deep inguinal lymph nodes in the connective tissue of the upper thigh. There is a chain of about 10 superficial (close to the surface of the skin) inguinal lymph nodes located in the upper inner thigh. Thereof, where are the lymph nodes in the legs? ![]() But there are clusters of them in places like your neck, under your arm and in the crease between your thigh and your torso (where your leg begins).
