1 Glands in the armpit (axillary lymph nodes) may swell from an injury or infection to the arm or hand. 2  A rare cause of axillary swelling may be breast cancer or lymphoma. 3  The lymph nodes in the groin (femoral or inguinal lymph nodes) may swell from an injury or infection in the foot, leg, groin, or genitals. Lymph nodes are small, bean-shaped glands throughout the body. They are part of the lymph system, which carries fluid (lymph fluid), nutrients, and waste material between the body tissues and the bloodstream.

The lymph system is an important part of the immune system, the body's defense system against disease The first sign of lymphoma may be a painless swelling in the neck, under an arm or in the groin. An enlarged lymph node may cause other symptoms by pressing against a vein (swelling of an arm or leg), a nerve (pain, numbness or tingling), or the stomach (early feeling of fullness).  1 The lymph nodes in the groin (femoral or inguinal lymph nodes) may swell from an injury or infection in the foot, leg, groin, or genitals. 2  In rare cases, testicular cancer, lymphoma, or melanoma may cause a lump in this area.

The lymph system is an important part of the immune system, the body's defense system against disease The most common cause of swollen lymph nodes is an infection, particularly a viral infection, such as the common cold. However, there are other types of infections, including parasitic and bacterial, and other possible causes of swollen lymph nodes. They include:  The popliteal nodes, or popliteal lymph nodes, include six or seven nodes and are located in the legs near the knees at the popliteal fossa. They service the lower legs and feet for the lymphatic system. The popliteal lymph nodes are in two sets: the deep popliteal nodes near to the popliteal vessels and the superficial popliteal lymph node associated with the small saphenous vein. The deep lymphatic trunks and lateral superficial trunks within the legs feed them. In the popliteal node, a .. Enlarged lymph nodes above the collar bone (supraclavicular lymphadenopathy) are always considered to be abnormal. These generally suggest a cancer of or an infection in the region close by. Examples of these may include lung infection, lung cancer, lymphoma in the chest cavity, or breast cancer. Occasionally more distant cancers may seed these lymph nodes, such as genital cancers or colon cancer. There are many adult lymph nodes in varying parts of the body that may become swollen for different reasons. Many people can usually see swollen lymph nodes on the neck, behind the ear, under the jaw, above the collar bone, under the arms, and around the groin. Swollen lymph nodes on the side of the neck or under jaw are the most common. They may represent an infection around that area, such as a tooth infection or abscess, throat infection, viral illness, or upper respiratory infection
