    Can one get colon cancer 3 years after clean colonoscopy

    I had a colonoscopy 8 years ago which found 3 noncancerous polyps and they were removed. 3 years ago I kept having diarrhea for 2 months which prompted a second colonoscopy. The second colonoscopy was clean. I have been having abdominal pain for almost a year now and the doctors couldn't tell the causes after running many tests like MRI blood test. Every test came back normal except for elevated CEA (3.4) Recently I noticed reddish stool. The PCP did a rectal exam but found no blood. I will have the third colonoscopy this Friday. What is the chance I have colon cancer?

    Sorry your worry has brought you here posting on a cancer support site. However, you ask "what are the chances". We can not possibly guess the cause of your current health worry. You are doing the correct course of action by having another colonoscopy, at the referral of your doctor?

    Your abdominal pain, recent reddish stool can be a symptom of so many things least one being cancer. IBS, diet and the list goes on.

    Follow through with the test then see what, if any, it reveals and listen to what your doctor has to say.

    Good luck to you.

    Just had my colonoscopy today. The GI said everything appears normal. He said there were some non bleeding hemorrhoids. He took biopsy of the terminal ileum although he said it looks normal. He did not say what the biopsy was for. Maybe he did but I was too drowsy.. Does anyone know why the ileum need a to be biopsied? I am trying to stay away from googling

    Anyway I am grateful that no mass no polyps found.

    One more question. The previous 2 colonoscopies I had the laxative stoped after the procedures. This time I am still having diarrhea 9 hours after it was done. The last time I took the laxative (ez2go) was 16 hours ago. Is this normal

    Simple answer,
    Yes loose bowels can continue for many hours after the procedure and dependent upon the laxative you took as well as diet and anxiety.

    Overall a good outcome which should please you.
    Dont get over obsessed as anxiety is a sure condition to change your bowel movements.

    Thanks Barry. I am not worried about the loose tool, just a little curious. . Yes I was relieved that the colonoscopy was normal but at the same time I still do not know what causes my abdominal pain which has been going on for so long.

    So I had a clean upper endoscopy last year when the pain started. Now a clean colonoscopy. So I guess the entire GI tract is normal. Abdominal MRI and MRI MRCP were also normal. The previous GI gave me a couple of IBD meds like bentyl but none helped

    Will work with this new GI to see if he has any other ideas

    I Will come back to update everyone
