Is it colorectal cancer or hemorrhoids?


In the past, there were a few instances of blood in the toilet after bowel movements, but now there is a small amount of bright red blood on the tissue after wiping, which has been happening for several months.
There was one occasion when the bleeding was significantly more, and there is pain around the anus.
I visited a doctor, but it seems there wasn't much explanation given.
Currently, my stools are yellow and thin, appearing in several strips.
What could these symptoms indicate?

When it comes to gastrointestinal symptoms such as rectal bleeding, changes in bowel habits, and discomfort, it is essential to approach the situation with caution and seek medical advice. Your symptoms, including the presence of blood after bowel movements, pain around the anus, and changes in stool consistency, can be concerning and warrant further evaluation.

Firstly, the presence of bright red blood on toilet paper or in the toilet bowl after a bowel movement is often associated with hemorrhoids or anal fissures. Hemorrhoids are swollen veins in the lower rectum and anus that can cause discomfort, itching, and bleeding, especially during bowel movements. Anal fissures, which are small tears in the lining of the anus, can also lead to pain and bleeding, particularly if the stool is hard or if there is straining during defecation.

The fact that you have experienced blood intermittently over several months, along with pain, suggests that hemorrhoids or fissures could be the primary cause. However, it is crucial to note that while these conditions are common and often benign, rectal bleeding can also be a symptom of more serious conditions, including colorectal cancer, especially if there are additional risk factors present.

Colorectal cancer can present with a variety of symptoms, including:
- Changes in bowel habits (such as diarrhea or constipation)
- Blood in the stool (which may appear dark or tarry)
- Unexplained weight loss
- Abdominal discomfort or pain
- A feeling that the bowel does not empty completely
Given your age and the intermittent nature of your symptoms, the likelihood of colorectal cancer is generally lower, especially if you do not have a family history of the disease. However, the presence of blood, especially if it is significant or accompanied by pain, should not be ignored. It is essential to consult with a healthcare professional who can perform a thorough evaluation, which may include a physical examination, a digital rectal exam, and possibly a colonoscopy to visualize the colon and rectum directly.

In your case, since you have already seen a doctor and did not receive a definitive diagnosis, it may be beneficial to seek a second opinion or request further testing. A gastroenterologist can provide specialized care and may recommend a colonoscopy, especially if your symptoms persist or worsen. This procedure is a standard diagnostic tool that allows for direct visualization of the colon and can help identify any abnormalities, including polyps or tumors.

In the meantime, it is advisable to maintain a high-fiber diet, stay hydrated, and avoid straining during bowel movements to help manage your symptoms. Over-the-counter treatments for hemorrhoids, such as topical creams or suppositories, may also provide relief if hemorrhoids are the cause of your symptoms.

In summary, while your symptoms may suggest hemorrhoids or anal fissures, the presence of blood and pain should prompt further investigation to rule out more serious conditions. It is crucial to communicate openly with your healthcare provider about your symptoms and any concerns you may have. Early detection and intervention are key to managing gastrointestinal health effectively.
