Which lymph nodes are swollen can help identify the problem. 1  The glands on either side of the neck, under the jaw, or behind the ears commonly swell when you have a cold or sore throat.  Glands in the armpit (axillary lymph nodes) may swell from an injury or infection to the arm or hand.
These include lymph nodes in the armpits, neck, and groin. A lump at one of these sites does not necessarily indicate lymphoma. Swollen lymph nodes are more likely to be caused by infection than cancer. For example, swelling in the lymph nodes of the neck is frequently linked to throat infections. Lymphocytes, or white blood cells, flood the nodes during infection.
