Treatment guide
Stage I (T1) colon cancer
Chart 5.1.2
addresses follow-up testing for polyps
with cancer. Follow-up testing is started when
there are no signs of cancer after treatment. It can
be helpful for finding new cancer growth early. A
colonoscopy is recommended 1 year after treatment
has ended.
If results are normal, have your next colonoscopy in
3 years and then every 5 years. If the test finds an
advanced adenoma, your next colonoscopy will be
needed within 1 year. Advanced adenomas include a
villous polyp, a polyp larger than the width of an AAA
battery, or a polyp with pre-cancerous cells.
