I had a removal of what was supposed to be a large cyst, In May this year. In June I I was told that following Thoracotomy for right upper lung lobe removal. That the cyst of 7cm was growing attached to 11cm of a rare form of adenocarcinoma. It was removed encapsulated in the lobe with no lymph node involvement. I had no obvious symptoms. No chemo or radiotherapy. I will undergo the 5 year regime of serial X Rays. Started last week. 3 monthly for 2 years. 6 monthly for 3 years, then yearly for life. I have never smoked, alcohol occasionally, I had sarcoidosis in the same lung area but no problems and otherwise healthy.
