[|Human|] Hi I was wondering what the chances of having colon cancer. I had a cat scan with contrast and it showed something on my colon. I also feel like someone has punched me in my stomach and llq pain. Other then a weird feeling around my naval I show no other signs.
[|AI|]  Hi, I appreciate your concern. Colon carcinoma usually presents with Iron-deficiency anemia, Rectal bleeding, Abdominal pain, Change in bowel habits, Intestinal obstruction. Nonspecific findings like fatigue, weight loss etc. can also occur. More advanced disease can present with abdominal tenderness, macroscopic rectal bleeding, palpable abdominal mass, hepatomegaly, ascites etc. So without knowing your detailed history, physical findings and imaging findings, it is very difficult to say the exact etiology. Hope it helps
