I have enlarged lymph nodes in the hollow space above my left collar bone. could this be lymphoma?

Any other symptoms?: Many things can cause swelling of lymph nodes. Other symptoms you are having may help differentiate between them. Do you have symptoms like fevers, weight loss, night sweats? Infections, inflammatory conditions or some cancers like lymphoma can do this but most lymph node swellings are not cancer. This should be evaluated by a physician.
