                        I have a friend who once had a tumor or such removed from the surface of her lung. She's OK now, by getting her operation real fast.  Don't waste time; see a Doctor now, preferably a pulmonary specialist!  (It could also be an embolism, fibrosis, etc. - none of which can be ignored!)   .  Good Luck!
