Colorectal Cancer - When To Call a Doctor

Call your doctor if you have any symptoms of colorectal cancer, such as:

  • A change in bowel habits.
  • Bleeding from your rectum, including bright red or dark blood in your stools or stools that look black.
  • Constant or frequent diarrhea, constipation, or a feeling that your bowel doesn't empty completely.
  • Stools that are narrow (may be as narrow as a pencil).
  • Belly pain or problems with gas or bloating.
  • Unexplained weight loss.
  • Constant tiredness (fatigue).

Because colorectal cancer often doesn't cause any symptoms, talk with your doctor about screening tests. Screening helps doctors find a certain disease or condition before any symptoms appear.

Absence of muscularis invasion or regional metastases may justify local excision.[1] The outcome from treating a lesion between 1 cm and 2 cm is unclear. The metastatic risk is between 10% and 15%.[6]...
