The size of the lymph nodes generally depends on the person’s age, location, and immune activity. This gland does have the capacity to enlarge its size.

Lymphadenopathy can usually be felt under the chin, in the neck, in the armpits, or in the groin. This condition is usually not classified as a serious medical problem. However, lymphadenopathy may be an early sign of a serious illness.
