Can you tell me if it's likely that I have colon cancer if all tests are clear?

Probably not: By all tests I assure that you are referring to blood samples as well as colonoscopy. If the blood tests are neg. they have no diagnostic value at the present time. Most are CA or carbohydrate antibodies with about a 50-60 % validity in dx. Colonoscopy would, at the present time be the best way to assure the bowel is free from CA. If that test was neg. then at least for 5 yrs. you are fine. ...Read more

What do you suggest if my CEA test was a 3. should I do something else . I had colon cancer in 1997?

What do you suggest if my CEA test was a 3. should I do something else . I had colon cancer in 1997?

Chill: Three is normal, my friend. Colon cancer would be unlikely to relapse after 15 years plus. Of course, you could develop another colon cancer so you need to keep your follow ups with your oncologist and get your colonoscopies religiously. Live healthy and if you smoke, quit (that will increase the CEA, by the way). ...Read more
