I had the Whipple 6 1/2 years ago, in January I had my left lung removed because of cancer. My CA-19 numbers went down to 13. Two months later the went to 256, now two more months they are up over 2000. My ct scan doesn't show any cancer, but with the pet scan in could be in my right shoulder, but doctor thinks its arthritis. I also lost my voice which they said there was no cancer there....I'm so worried. any thoughts
