Medical information regarding lymphadenopathy, or swollen lymph nodes, highlights that these occurrences are frequently an immune response to benign conditions such as viral or bacterial infections. Common causes include colds, flu, strep throat, and dental issues.

Medical professionals assess characteristics like size, mobility, tenderness, and growth rate to differentiate between infection and more serious concerns. While cancer is a possible cause, experts note it is not the most common reason for swelling. Individuals are advised to seek medical consultation if lumps persist for more than two to four weeks, continue to grow, or remain after an infection has cleared.
