Understanding swollen lymph nodes in the neck

Swollen lymph nodes in the neck are a common occurrence, often resulting from an immune response to infections such as colds, sore throats, tonsillitis, or ear and dental infections. While these lumps can be tender to the touch, they typically shrink once the underlying inflammation is controlled.

Medical experts, including Dr. Tyler Benning from the Mayo Clinic, note that while cancer is a possible cause of enlarged lymph nodes, it is not the most common reason. Other potential causes include immune system disorders or specific infections like mononucleosis or tuberculosis.

Individuals are advised to seek medical consultation if the lumps persist for more than two to four weeks, continue to grow, or remain present even after an infection has cleared. Doctors evaluate several factors, including the duration of the swelling, to determine the cause.
