I am looking for anyone with a pancoast tumor diagnoisis. I am wondering what your symptoms were--I have severe shoulder pain and down my arm. Had rotator cuff surgery 4 years ago but the cuff is fine. I am 70 yrs. old and a smoker. I know that pancoast tumor can cause the symptoms I am having but ct scan shows just an 8mm nodule in right apex of lung and doctor says nothing to worry about but no-one seems to have a solution for the pain. Any info would be greatly appreciated.
