Could My Symptoms Indicate Colorectal Cancer? Digestive Issues

Could this be colon cancer?

Hello Doctor, since June, I have been experiencing frequent diarrhea, with my bowel movements changing from a regular once a day to 1 to 3 times a day.
At that time, I consulted a doctor who diagnosed me with irritable bowel syndrome.
After taking medication twice, my condition changed to occasional diarrhea, but sometimes my stools were as thin as a finger.
I did not return for further consultation.
Last Tuesday, I had diarrhea twice, both times with red blood in the stool.
The next day, I had diarrhea three times, but there was no blood, accompanied by persistent lower abdominal pain.
When I visited the doctor, I weighed myself and found that my weight had decreased from 90 kg in June to 85 kg (without any intentional weight loss).
The doctor suggested it might be gastroenteritis.
After taking the medication, I had 2 to 3 bowel movements a day, and in three days, only two were formed stools (still only the thickness of a finger), while the rest were diarrhea.
During this time, I also experienced the urge to defecate but was unable to do so.
After the second round of medication, I continued to have 2 to 3 bowel movements a day, none of which were formed, and my lower abdomen occasionally still experiences sudden pain.
There is no history of colorectal cancer in my family, but after researching online, I found that aside from anemia, my symptoms seem to align with colorectal cancer.
Should I continue to observe my condition for a while? Do these symptoms match any other diseases? Additionally, besides porridge, what other foods can I eat for gastroenteritis? Thank you, Doctor.

Hello Mr.
Avi, based on your description, irritable bowel syndrome, colorectal cancer, and other inflammatory bowel diseases are all possibilities, especially considering the weight loss you mentioned.
You may want to discuss this with your doctor for further evaluation.
Thank you for your question.

More Info

Your symptoms certainly warrant careful consideration, especially given the changes in your bowel habits, the presence of blood in your stool, and the significant weight loss you've experienced. While I cannot diagnose you, I can provide some insights based on your description and general medical knowledge.

Colorectal cancer can present with a variety of symptoms, many of which are non-specific and can overlap with other gastrointestinal disorders. Common symptoms of colorectal cancer include:
1. Changes in Bowel Habits: This can include diarrhea, constipation, or a change in the consistency of your stool. You mentioned that your stool has varied in size and consistency, which is a symptom that can be associated with colorectal cancer.

2. Blood in Stool: The presence of red blood in your stool is concerning. While it can be caused by hemorrhoids or anal fissures, it can also indicate more serious conditions, including colorectal cancer. The fact that you have seen blood on multiple occasions is particularly important.

3. Abdominal Pain: Persistent abdominal pain, especially if it is new or worsening, should be evaluated. You noted experiencing lower abdominal pain, which can be associated with various gastrointestinal issues, including cancer.

4. Unexplained Weight Loss: Losing weight without trying, as you have described (from 90 kg to 85 kg), is a significant red flag. This can indicate that your body is not absorbing nutrients properly or that there is an underlying condition that needs to be addressed.

5. Other Symptoms: Symptoms like fatigue or anemia can also be associated with colorectal cancer, especially if there is chronic blood loss.

Given your symptoms, it is crucial to follow up with a healthcare provider. They may recommend further diagnostic testing, such as a colonoscopy, which is the gold standard for evaluating the colon and can help identify any abnormalities, including polyps or tumors. A stool test for occult blood may also be suggested to check for hidden blood in your stool.

Regarding your question about diet during a bout of gastroenteritis, it's essential to focus on hydration and easily digestible foods. In addition to rice porridge (congee), you might consider:
- Bananas: They are gentle on the stomach and can help replenish potassium.

- Applesauce: This is easy to digest and can provide some fiber.

- Toast: Plain toast can help settle your stomach.

- Boiled Potatoes: These are bland and easy to digest.

- Clear Broths: Chicken or vegetable broth can help keep you hydrated and provide some nutrients.

Avoid fatty, spicy, or highly fibrous foods until your symptoms improve.
In summary, while your symptoms could be indicative of various gastrointestinal issues, including inflammatory bowel disease or infections, they also align with potential signs of colorectal cancer. It is essential to consult with a healthcare professional for a thorough evaluation and appropriate testing. Early detection is key in managing any potential issues effectively.
