Dear TILULA1: Most normal lymph nodes measure 1 cm or less. Lymph nodes can become enlarged for a variety of reasons, the most common being inflammation or infection. Enlarged lymph nodes can last a long time depending on the reason for their enlargement. However, size is not the only characteristic that might be evaluated. Your doctor, who can do an examination, including evaluation of the lymph node, will be best suited to determine whether this has any suspicious qualities and whether additional evaluation is necessary.
