Diagnosis and Treatment

SaintThomasCancerCare_350In most cases, colon cancers begin as small, non-cancerous growths on the colon wall called polyps. As the polyps grow, they can cause bleeding or obstructions in the intestine. Not all polyps need surgery, though. Through advancements in technology, Saint Thomas Cancer Care doctors can remove polyps without the need for surgery.

Some common symptoms of colon cancer can include:

  • Blood in toilet or stool after a bowel movement
  • Rectal bleeding
  • Prolonged constipation or diarrhea
  • An urge to have a bowel movement when there is no need
  • A change in the size or shape of your stool

You should see your doctor if one or more of these persists for more than two weeks.
