Re: how long does cancer take to grow in colon
Occult blood can be a sign of many things, but is a good reason to get a colonoscopy. I did after a positive hemoccult and mine turned up a "tubular villiform adenoma with high-grade dysplasia". I looked it up, of course, and found that the percentages of these turning into cancer over 5-10 years is still relatively low- in other words, this type was pretty slow-growing. That's why most of the time they give you another 3-5 years before you come back. My doc wants to see me in another year, which I think is conservative, but having been through the colonoscopy and found it manageable (without sedation- see separate thread on that), I'll happily be back on schedule.
