Lymph nodes swell as a result of the body trying to fight off illness and usually appear in an area close to the disease or illness. A cold or other infection can cause swollen lymph nodes in the neck, but oral cancer is a less-common but possible cause as well. If the lymph node remains swollen longer than a few weeks, is larger than 1/2 an inch, or feels hard and rubbery and does not move, it is a good idea to get it checked by a doctor.
