Bowel issues


Hello doctor, I am 18 years old.
Recently, for the past month, I have frequently felt the urge to have a bowel movement, but I don't always have one.
When I do, the stool is thin and small.
Additionally, I have been experiencing occasional lower abdominal pain in the past few days.
Am I at a high risk for colorectal cancer?

Niming, 10~19 year old female. Ask Date: 2017/01/23

Dr. Ke Fangxu reply Surgery


At the age of 18, the likelihood of developing colorectal cancer is not zero, but it is generally very low.
Based on your description, it seems more like hemorrhoidal swelling.
It is recommended to maintain a light diet and a good lifestyle routine.
Spicy, irritating, and greasy foods should be avoided.
If symptoms persist without improvement, you may consult a physician for medication.

When it comes to bowel issues and the risk of colon cancer, especially in younger individuals, it's essential to approach the situation with a clear understanding of the symptoms and their potential implications. At 18 years old, the likelihood of developing colon cancer is relatively low, particularly if there is no family history of the disease or other risk factors such as inflammatory bowel disease (IBD). The average age for colon cancer diagnosis is typically over 50, and most cases occur in individuals with specific risk factors.

Your symptoms of frequent urges to defecate, along with the passage of thin, small stools and occasional abdominal pain, could be indicative of several conditions, but they are not necessarily signs of colon cancer. One common condition that can cause these symptoms is irritable bowel syndrome (IBS), which is characterized by changes in bowel habits, abdominal discomfort, and bloating. IBS is often triggered by stress, dietary factors, or changes in routine, and it can lead to both constipation and diarrhea.

The fact that your stools are thin and small could also suggest a functional issue with your bowel, such as a spasm or narrowing, but this is not definitive for cancer. It's important to note that while blood in the stool, significant weight loss, or a family history of colon cancer are red flags, your current symptoms do not strongly suggest malignancy.

If you are experiencing abdominal pain, it is crucial to monitor its nature—whether it is constant, intermittent, sharp, or dull. Pain that is persistent or worsening should be evaluated by a healthcare professional. Additionally, if you notice any changes in your bowel habits that are unusual for you, such as prolonged diarrhea or constipation, or if you experience any rectal bleeding, these should prompt a visit to a doctor.

In your case, it would be advisable to consult with a gastroenterologist who can perform a thorough evaluation, which may include a physical examination, a review of your medical history, and possibly some diagnostic tests. These tests could include blood work, stool tests, or imaging studies to rule out any underlying conditions.

In summary, while your symptoms warrant attention, the risk of colon cancer at your age is low, especially in the absence of alarming symptoms. However, it is always best to err on the side of caution and seek medical advice to ensure your health and peace of mind. Maintaining a healthy diet, staying hydrated, managing stress, and regular physical activity can also contribute positively to your digestive health.
