When to see the doctor
See your doctor yearly for colon cancer screening beginning at age 50. Talk to your doctor sooner about colon cancer screening if you have a first degree relative (parent, sibling or child) with colon cancer or familial adenomatous polyposis (FAP) or hereditary nonpolyposis colorectal cancer (HNCC) as screening should start at age 40 or earlier.
The symptoms of colon cancer are:
- Rectal bleeding or blood in your stool.
- Changes in your bowel habits, such as diarrhea, constipation or narrowing of the size of your stool that last more than a few days.
- Cramping or steady abdominal pain.
- Weakness, fatigue, jaundice or poor appetite.
- Unexplained weight loss.
