The doctor did a bronchoscopy with biopsies, that cam back non-cancerous, however mid April symptoms still exist after 3 rounds of antibiotics. Last week they performed a Electromagnetic Navigation Bronchoscopy - still 95% sure non-cancerous, however doctors have no idea what it is. round 4 of antibiotics, then prednisone to follow. if not better by May 18th, they want to refer me to a surgeon to have the mass removed without even knowing what it is. Please Help! Sincerely, Coughing up a Lung
