Is Blood in Stool a Sign of Colon Cancer? Your Symptoms

Blood in stool

Previously, I had bright red blood in my stool, and there was blood on the toilet paper when I wiped.
I was examined by a doctor and diagnosed with hemorrhoids.
After a while, the bleeding stopped, but recently I have started experiencing constipation (having a bowel movement every five to seven days), and there is still some blood mixed in with the stool (the amount of blood is not significant).
There are no blood stains on the toilet paper when I wipe, which is different from the previous symptoms of hemorrhoid bleeding.
I would like to know if this could be a symptom of colorectal cancer.
Thank you.

Dear Concerned Sir/Madam, based on your condition, what you need most is to visit a nearby medical facility and arrange for a colonoscopy with a gastroenterologist.
This will help determine the cause of the bleeding and rule out the possibility of colorectal cancer.

More Info

Blood in the stool can be a concerning symptom, and it's understandable to worry about the possibility of colon cancer. However, it's important to consider various factors before jumping to conclusions. Based on the information you've provided, it seems that you have a history of hemorrhoids (痔瘡), which can often cause rectal bleeding. This is especially relevant since you mentioned that your previous bleeding episodes were attributed to hemorrhoids.

When evaluating blood in the stool, several potential causes should be considered. Hemorrhoids are swollen blood vessels in the rectum or anus that can bleed, especially during bowel movements. They are quite common and can be exacerbated by factors such as constipation, straining, or a low-fiber diet. Given that you've recently experienced constipation, this could be a contributing factor to your current symptoms.

In your case, the blood you are seeing mixed with your stool could still be related to hemorrhoids, particularly if the bleeding is minimal and not accompanied by other alarming symptoms such as significant abdominal pain, weight loss, or changes in bowel habits. However, the fact that you are experiencing constipation and have noticed a change in the nature of your stool (such as blood being mixed in rather than just on the surface) does warrant further investigation.

Colon cancer is less common in younger individuals, but it is not impossible. Symptoms of colon cancer can include changes in bowel habits, blood in the stool (which may appear bright red or dark), unexplained weight loss, persistent abdominal discomfort, and fatigue. However, these symptoms can also be associated with other conditions, such as inflammatory bowel disease (IBD), diverticulitis, or infections.

Given your symptoms and history, it would be prudent to consult a healthcare professional, preferably a gastroenterologist, for a thorough evaluation. They may recommend a colonoscopy, which is a procedure that allows doctors to examine the inner lining of the colon and rectum. This can help identify any abnormalities, such as polyps or tumors, and also allow for biopsies if necessary.

In the meantime, consider making dietary changes to improve your bowel health. Increasing your fiber intake through fruits, vegetables, and whole grains can help alleviate constipation and reduce straining during bowel movements. Staying hydrated is also crucial, as it can help soften stool and promote regularity.

In summary, while blood in the stool can be a sign of colon cancer, it is more commonly associated with benign conditions like hemorrhoids, especially in younger individuals. However, due to the change in your symptoms, it is essential to seek medical advice to rule out any serious conditions and to receive appropriate treatment for your constipation and any other gastrointestinal issues you may be experiencing.
