What are symptoms?


Colorectal cancer (cancer in the colon or rectum) first develops with few, if any, symptoms. Be proactive and talk to your doctor. Do any of the following scenarios apply to you?

Have you seen a change in your bowel habits?

This includes intermittent or constant diarrhea and/or constipation, a change in the consistency of your stool, or more narrow stools than usual.

Do you have persistent abdominal discomfort?

This can present as cramps, gas, or pain and/or feeling full, bloated, or a feeling like your bowel is not completely empty. Nausea and/or vomiting can also be a symptom.

Do you have rectal bleeding?

Is there blood in your stool? The blood can be bright red, or the stool may be black and tarry or brick red.

Do you feel weak or fatigued?

This may be accompanied by anemia or a low red blood cell count.

Do you have unexplained weight loss?

If you're losing weight for no known reason, nausea, or vomiting, then it could be a symptom of colorectal cancer.

When should I see a doctor?


Earlier is better! Colon and rectal cancer symptoms can also be associated with many other health conditions. Only a medical professional can determine the cause of your symptoms.

Since the early signs of cancer often do not include pain, it is important not to wait and see your doctor soon. Remember, early detection can save your life.

When it comes to colorectal cancer, 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
