I have had surgery to remove a mediastinal mass, there was a tumor on my thymus. I has open surgery and the rugby ball sized mass weighting two Kilo was removed in one piece. It had been attached to my heart, windpipe, lungs and cavity wall.  The surgeon said it all had been removed and they took fine pieces off the organs it was attached to and a pleural biopsy to see if the lung is cancerous, all scans etc leading up to survey were clear except for the mediastinal mass.  Has anyone experience of this cancer. I'm now gone after major surgery but don't see the consultant for ten days yet and as it stands in expect ing the worst. They are giving me chemo as a mop up precaution. It's so hard being positive but if anyone could shed some light. Am I terminal? Does complete surgery and removal cure this?
