[|Human|] I just had a ct scan and the results showed several lymp nodes in the mediastinal area. I guess that means in the middle if the chest or under my breat bones. I am scheduled to see a throaxic specialist on Friday. I guess I spelled it right.  Can you possible tell me some of the causes.  thanks
