Symptom List


Colorectal cancer (cancer in the colon or rectum) 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

Colorectal cancer 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.

When to See a Doctor


The symptoms of colon cancer and rectal cancer 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! #tomorrowcantwait
