Constipation and Its Potential Link to Colorectal Cancer

Constipation issues?

Doctor, I previously had normal bowel movements, but I have now developed diarrhea (which has not improved much).
The internet suggests it could be colon cancer.
I also experience lower abdominal pain, specifically in the same area, and I often pass gas (I'm not sure if it has an odor).
Once, I noticed blood on the toilet paper after a bowel movement (but I didn't see blood in the stool).
Recently, my bowel movements suddenly changed from semi-diarrhea to constipation, even though I haven't changed my diet or lifestyle.
My stools are often flat and small, and after producing one or two larger pieces, I feel the urge to go but can only pass very thin, soft stools.
The internet suggests that these symptoms could indicate stage 2 or 3 cancer...
So I would like to ask the doctor: 1.
Is it possible to have colon cancer at the age of 12? 2.
If eating a banana helps relieve my constipation, could it still be colon cancer? (Because I think I once had a normal bowel movement after eating a banana, but then I started to be constipated again.) 3.
Should I persuade my parents to get me checked? 4.
What stage of colon cancer do these symptoms most likely indicate?

Dr. Chen Shidian reply Gastroenterology and Hepatology

It is likely a case of abnormal peristaltic digestion.
Increasing the intake of fruits and vegetables is recommended, and further observation is advised.

When it comes to understanding constipation and its potential link to colorectal cancer, it's important to recognize that many of the symptoms associated with bowel irregularities can be caused by a variety of factors, not just cancer. In your case, you are experiencing a range of symptoms including changes in bowel habits, abdominal pain, and occasional blood in your stool. Let's address your questions one by one.

1. Is colorectal cancer possible at the age of 12?
Colorectal cancer is extremely rare in children and adolescents. The vast majority of cases occur in individuals over the age of 50. While there are certain genetic conditions that can predispose younger individuals to colorectal cancer, such as familial adenomatous polyposis (FAP) or Lynch syndrome, these are uncommon. Your age significantly lowers the likelihood of having colorectal cancer, but it does not completely eliminate the possibility.
2. Could eating bananas and experiencing changes in bowel movements indicate cancer?
Bananas are known for their fiber content, which can help regulate bowel movements. If you find that eating bananas helps alleviate your constipation, it suggests that your bowel issues may be related to dietary fiber intake rather than a serious underlying condition like cancer. However, the fact that your bowel habits fluctuate between diarrhea and constipation could indicate an underlying gastrointestinal issue, such as irritable bowel syndrome (IBS), rather than cancer.

3. Should you persuade your parents to get you checked?
Given your symptoms, it would be prudent to discuss your concerns with your parents and seek medical advice. While the likelihood of cancer is low, it is essential to rule out any other potential gastrointestinal disorders. A healthcare professional can perform a thorough evaluation, which may include a physical examination and possibly imaging or endoscopic procedures if deemed necessary.

4. What stage of cancer might this situation indicate?
It is not appropriate to speculate on the stage of cancer based on your symptoms alone, especially given your young age. Symptoms such as changes in bowel habits, abdominal pain, and blood in the stool can be associated with various conditions, including benign ones. Staging of cancer typically involves imaging studies and biopsies, which can only be performed by a healthcare professional.

In summary, while your symptoms warrant attention, the likelihood of colorectal cancer at your age is very low. It is crucial to maintain open communication with your parents about your health concerns and seek medical advice. A healthcare provider can help determine the cause of your symptoms and recommend appropriate treatment or lifestyle changes. Remember, many gastrointestinal issues can be managed effectively with dietary adjustments, stress management, and sometimes medication.
