Stages I (T2), II, and III colon cancer
Follow-up testing is for people who have no signs of
cancer after treatment. It can be helpful for finding
new cancer growth early. Tests differ based on
whether the cancer is stage I versus stages II and III.
Chart 5.2.3
lists the follow-up tests for stage I (T2
tumors) cancers. 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.
Chart 5.2.4
lists the follow-up tests for stage II and
III cancers. You should receive a medical history and
physical exam every 3 to 6 months for 2 years. If
results are normal for 2 years, then get these tests
every 6 months for 3 years.
