I had a CAT scan in March 2016 after having a kidney stone removed. they seen a spot on my lung and said I should follow up on it. another CAT scan had showed it increased in size. A awesome surgeon named Lanny Dunham in Denver CO used a new procedure with a robot to take out the spot. he removed it all. it was stage 1 cancer. he also removed some lymph nodes and there was no cancer in them. I am a very lucky woman to have had a doctor wanting to use new technology as most doctors would have watched it longer and then it would have moved to another stage of cancer.
