I have had precancerous polyps in the past so I was told to do another one in 5 years when I would be 82. I did a consult at Mayo first to see if I should go ahead with it given my age and my lung and breathing issues (safety for general anesthesia). They said yes and I had it and I am glad I did because they removed 3 precancerous polyps 2, 10 and 12 mm (the most and the largest I have every had at one time). They told me to repeat in 3 years when I will be 85!
