Blood in Stool and Abdominal Pain: Is It Colon Cancer?

Blood in stool accompanied by abdominal pain?

Last month, I experienced severe constipation for about three days without a bowel movement.
After going to an all-you-can-eat restaurant, I felt the urge to go, but it was very painful, especially when the stool was passing.
There was fresh blood on the stool and on the toilet paper, but it stopped after the second wipe.
For several days, the bowel movements were quite painful, and I noticed blood again.
I increased my water intake, which improved my condition, and my stool became golden yellow.
However, last week, I experienced some constipation again, with hard, pellet-like stools.
The next day, the bowel movement was painful again, and there was blood.
I continued to increase my water intake, and it got better.

On March 18, I only drank about 500 cc of fluids.
There was no blood on the surface of the stool, but fresh blood flowed from the side of the toilet; it was a small amount.
The stool had both golden yellow and darker colors, with a significant difference in texture between the two.
Could this be colon cancer? I have been eating fewer vegetables, and for the past three weeks, there has been no blood in my stool, which has been very golden yellow.
I used to have a bowel movement every 2-3 days, but now I go twice a day.
Additionally, I have had bloating about 5 cm above my navel for approximately two weeks, which only hurts when pressed deeply; otherwise, it just feels bloated.
Could this be colon cancer?

Dr. Ke Fangxu reply Surgery

At 16 years old, it is unlikely to be colon cancer.
Changes in bowel habits are most often related to dietary changes, or they could be due to gastroenteritis or lactose intolerance.
It is advisable to maintain a light diet and avoid dairy products for a while.
If there is no improvement after a few days, it would be wise to consult a physician for further evaluation.

When considering the symptoms you've described—abdominal pain, blood in the stool, and a family history of colon cancer—it's essential to approach this situation with caution and thoroughness. While I cannot provide a definitive diagnosis, I can help you understand the potential implications of your symptoms and the importance of seeking medical attention.

Firstly, the presence of blood in the stool can arise from various conditions, some of which are benign, while others may be more serious. Common causes of blood in the stool include hemorrhoids, anal fissures, diverticular disease, and inflammatory bowel disease (IBD), such as Crohn's disease or ulcerative colitis. However, given your family history of colon cancer, it is crucial to consider the possibility of colorectal cancer, especially since you have experienced recurrent symptoms.

Your description of abdominal pain, particularly localized pain that worsens with pressure, could indicate several issues. It might suggest an underlying gastrointestinal condition, such as an obstruction, inflammation, or even a mass. The fact that you have experienced constipation and hard stools can also contribute to anal fissures or hemorrhoids, which can cause bleeding. However, the intermittent nature of your symptoms and the presence of blood warrant further investigation.

The family history of colon cancer is particularly significant. Individuals with a first-degree relative (like a parent or sibling) who has had colon cancer are at an increased risk for developing the disease themselves. Given that both your grandfather and mother had colon cancer, this elevates your risk profile. Regular screenings, such as colonoscopies, are recommended for individuals with a family history of colorectal cancer, typically starting at an earlier age than the general population.

In your case, the changes in your bowel habits, the presence of blood, and the abdominal discomfort should prompt you to seek a consultation with a gastroenterologist. They may recommend a colonoscopy to visualize the colon and rectum directly, allowing for the identification of any polyps, tumors, or other abnormalities. Additionally, they may perform biopsies if any suspicious lesions are found.

It's also worth noting that lifestyle factors, such as diet and hydration, play a crucial role in gastrointestinal health. Increasing your intake of fiber-rich foods, such as fruits, vegetables, and whole grains, can help prevent constipation and promote regular bowel movements. Staying well-hydrated is equally important, as it can soften stools and reduce the risk of straining during bowel movements.

In summary, while your symptoms could be attributed to several conditions, the combination of blood in the stool, abdominal pain, and a family history of colon cancer necessitates a thorough evaluation by a healthcare professional. Early detection and intervention are vital in managing potential colorectal issues effectively. Please prioritize scheduling an appointment with a gastroenterologist to discuss your symptoms and undergo the necessary diagnostic tests. Your health and well-being are paramount, and addressing these concerns promptly can lead to better outcomes.
