Everyone gets sick from time to time, but it’s occasionally more serious than just a head cold or a stomach bug.

When most of us have stomachaches, we just ignore them and try to move on with our day. Sure, we might think about whether we ate something bad or if there’s a stomach flu going around, but for the most part, we don’t really think too much about what’s wrong with us.

Once in a while, though, it’s something much more serious — like in the case of irritable bowel syndrome, stomach ulcers, or colorectal cancer.

All of these issues might start by feeling like nothing more than a regular stomachache, but they have much more serious consequences. Sometimes, it’s worth paying extra attention to your bowel movements and abdominal pain.

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.”

Signs And Symptoms Of Colorectal Cancer

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.

Sign #4: Change In Bowel Habits

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.

Sign #6: Unexplained Weight Loss

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.
