13 Early Warning Signs of Colon Cancer

Bowel Urges

Gong to the bathroom to have bowel movements or poop and not being able to relieve your urge to poop after finishing might be a sign of colon cancer. Bowel urges is different from constipation in which it is hard for you to pass stool. So basically, bowel urges is when you feel the need to poop or have a bowel movement several times a day and you just do not feel relieved and feel like you need to go again. Bowel urges are common in people who have cancer in their distant colon or rectum where cancer causes increased pressure in the bowel.

Blood in Stools

Finding any color (bright red or dark) of blood or mucous mixed with your stool/poop might be an indication of cancer. Cancer damages our blood vessel and ravages the walls of our colon as it grows. That can potentially cause the blood from our vessels to go into our colon which can be seen as drops of blood in the toilet, smear of blood on the toilet paper or in our stool.

Doctors can order a fecal occult blood test which is taking a sample of your stool to analysis in a pathology laboratory.

Cleveland Clinic said that the most telltale sign of colorectal cancer is blood in the stool. People should speak to their doctor if blood is visible in their stool because it can also be related to other health issues such as Chron’s disease, anal tears, hemorrhoids, ulcerative colitis and bleeding in the digestive tracts.


Almost everyone knows their body and how their bowel movements are and how it can change if they eat certain types of food.

People with colon cancer might have a change in their bowel movements.
Example: An individual who might have regular solid bowel movements might start going to the bathroom more frequently with looser bowel movements. You should see a doctor if those symptoms last for over a few weeks because it could be a sign of cancer.

Diarrhea and constipation are two different things.
Diarrhea is when you have an abnormal frequency of loose fluidity of fecal evacuations.
Constipation is when you have a difficult time passing stool which comes out hard and sometimes dry.

BMC Medicine Journal mentioned in one of their articles that one of every five colon cancer patient experience diarrhea and persistent diarrhea is not a good sign.

Blackish and Tarry Stool

You should see a doctor if you have blackish or tarry looking stool as it can be a sign of colon cancer. Your stool can look black or tarry when there is bleeding higher up in your colon because the blood then has time to break down before it exits your body. Bleeding from your stomach, small intestines or esophagus might cause your stool to be dark and tarry also.

Bowel cancer can make your stool look maroon or dark in color and make your stool appears sticky which can be a result of your intestine bleeding. Your stool may also be as thin as a pen or look like a ribbon or extremely narrow. Some cancer patients experience normal bowel movements between this abnormal movements.

Hard time Passing Stool

Hard time passing stool and constipation is different as hard time passing stool means that you are passing stool but it can be quite difficult to do so. Straining to pass your stool might make you feel as though you still have more fecal matter in your after leaving the bathroom. Having a difficult time passing stool may be a result of colon cancer large mass that possibly is blocking the intestinal lumen which makes it hard to pass stool.

Rectum Bleeding

About 50 percent or more people with colon cancer have experienced their rectum bleeding which is a very common sign of colon cancer. Rectum bleeding can be a result of a strenuous bowel movement. The blood is usually bright red. Bleeding can be a result of the colon cancer large mass which might have become ulcerates and bleeds everytime you try to poop.
