Most people with lung cancer do not need the entire lung removed and undergo a lobectomy. However mesothelioma is not your typical lung cancer and does not arise from the lung, but from the pleural around the lung. In early stage disease if all of the tumor cannot be removed without removing the lung then they will do a pneumonectomy. The best chance for cure is to do an extrapleural pneumonectomy. This is a very extensive surgery and should only be carried out by surgeons with great expertise in evaluating patients and performing the procedure itself. Best wishes I hope everything goes well for you.
