Let’s start by breaking down exactly what colorectal cancer means.

The US National Library of Medicine explains: “The colon and rectum are part of the large intestine. Colorectal cancer occurs when tumors form in the lining of the large intestine. It is common in both men and women. The risk of developing colorectal cancer rises after age 50.”

The American Cancer Society explains that rectal bleeding may also be a symptom of colorectal cancer.


The blood may appear as bright red, or it may just make your stool look dark and tarry.

Everyone’s bowel habits change from time to time, but if they last for more than a few days, it’s worth considering that it might be something serious.

The American Cancer Society writes that one of the symptoms of colorectal cancer is “a change in bowel habits, such as diarrhea, constipation, or narrowing of the stool.”

Sign #5: Feeling That Your Bowel Isn’t Empty

Another symptoms is “a feeling that you need to have a bowel movement that is not relieved by having one,” says the American Cancer Society.


This may also feel like your bowel is never completely empty.

One final symptom of colorectal cancer is unexplained and unintended weight loss.

If you’re dropping pounds unintentionally, it’s always something to take note of — it could mean something is seriously wrong with your health.
