Symptoms Similar to Colon Cancer: A Guide for Patients

Symptoms similar to colorectal cancer?

Hello Doctor, I have been experiencing dizziness for the past few months, which is similar to symptoms of anemia.
Previously, I had frequent rectal bleeding, and my intestines often made peristaltic sounds for a long time, usually occurring after meals.
However, I have not experienced any bleeding in the past month.
My stool has a yellow-green color and is not very thin, but slightly thinner than before.
There is always mucus when I wipe, and sometimes it is mixed with blood.
I also occasionally feel that my bowel is not completely empty.
After eating, I sometimes experience abdominal pain and have diarrhea in episodes, which alleviates after I finish.
I have also had alternating symptoms of constipation and diarrhea in the past.
Recently, I have lost my appetite.
I have been trying to lose weight, and my weight has decreased.
I have recently been taking probiotics (the Zhong Geng Tang brand).
Additionally, I would like to ask where I can get a stool occult blood test done.
Can I directly request the doctor to perform a stool occult blood test when I visit?

Hello Ms.

It would be safer to discuss your symptoms with the doctor.
Thank you for your question.

More Info

It sounds like you are experiencing a range of gastrointestinal symptoms that could be concerning, especially given your history of blood in your stool and other digestive issues. Let's break down your symptoms and address your questions.

Symptoms Overview
1. Dizziness and Anemia: Dizziness can often be a sign of anemia, which may be caused by chronic blood loss. If you have been experiencing blood in your stool, this could indicate a gastrointestinal bleed, which can lead to anemia over time.

2. Blood in Stool: The presence of blood in your stool, even if it has not occurred recently, is a significant symptom that should not be ignored. Blood can appear in different forms, such as bright red (indicating fresh blood) or darker (indicating older blood). The fact that you have experienced both blood and mucus in your stool could suggest an underlying issue, such as hemorrhoids, diverticulitis, or even more serious conditions like colorectal cancer.

3. Bowel Habits: The alternating symptoms of constipation and diarrhea, along with the sensation of incomplete evacuation, can be indicative of irritable bowel syndrome (IBS) or other gastrointestinal disorders. The yellow-green color of your stool may also suggest a change in digestion or bile production.

4. Loss of Appetite and Weight Loss: Unintentional weight loss and loss of appetite are concerning symptoms that warrant further investigation. These can be associated with various gastrointestinal conditions, including malignancies.

5. Abdominal Pain: Pain after eating, especially if it leads to diarrhea, can indicate a food intolerance or an inflammatory condition in the gastrointestinal tract.

Recommendations
Given your symptoms, it is crucial to seek medical attention. Here are some steps you can take:
1. Consult a Gastroenterologist: A specialist in gastrointestinal disorders can provide a thorough evaluation of your symptoms. They may recommend tests such as a colonoscopy, which allows direct visualization of the colon and rectum, and can help identify any abnormalities.

2. Fecal Occult Blood Test: You can request a fecal occult blood test (FOBT) from your primary care physician or gastroenterologist. This test checks for hidden (occult) blood in the stool, which can be an early indicator of colorectal cancer or other gastrointestinal issues.

3. Dietary Considerations: While you are taking probiotics, it’s also important to maintain a balanced diet rich in fiber to help regulate bowel movements. Avoiding processed foods and excessive fats can also be beneficial.

4. Monitor Symptoms: Keep a detailed record of your symptoms, including when they occur, their severity, and any associated factors (like food intake). This information can be invaluable for your healthcare provider.

5. Follow-Up: If you experience any new symptoms, such as increased pain, more frequent blood in your stool, or significant changes in your weight or appetite, seek medical attention promptly.

Conclusion
Your symptoms are concerning and warrant a thorough evaluation by a healthcare professional. While some symptoms may be benign, others could indicate a more serious condition. It is essential to address these issues early on to ensure the best possible outcomes. Don't hesitate to advocate for yourself during medical visits; you have the right to request specific tests and express your concerns.
