Colon cancer first develops with few, if any, symptoms. Be proactive and talk to your doctor.  If symptoms are present, they may include:

  • A change in bowel habits

    Including diarrhea, constipation, a change in the consistency of your stool or finding your stools are narrower than usual

  • Persistent abdominal discomfort

    Such as cramps, gas, or pain and/or feeling full, bloated or that your bowel does not empty completely

  • Rectal bleeding

    Finding blood (either bright red or very dark) in your stool

  • Weakness or fatigue

    Can also accompany losing weight for no known reason, nausea or vomiting

These symptoms can also be associated with many other health conditions. Only a medical professional can determine the cause of your symptoms. Early signs of cancer often do not include pain. It is important not to wait before seeing a doctor. Early detection can save your life.

Remember, the most common symptom is NO symptom, which is why we call it the silent killer. If you’re 50, average risk, get screened! #screenbrave
