In most cases, enlarged lymph nodes arise as a response to infection or/and inflammation in the body. However, in a minority of cases, enlarged lymph nodes can be a sign of lymphoma (a type of cancer that involves the lymph nodes), or a sign of cancer that has spread to the lymph nodes from some other area of the body.
I would suggest that you have your physician evaluate you further.
