Hello Doctor,
Three weeks ago, I experienced red blood in my stool for three days, along with black stool. However, two days ago, I had hemoglobin and occult tests, and the results were all normal. Does this mean I do not have colon cancer?
Hello,
Thank you for reaching out to Dr. Galen. Please find the below response to your query.
Blood in stool is never normal. It’s a sign that further investigation is needed. Black stool could be from an upper gastrointestinal source, or it could be from certain foods and/or medications such as iron supplements or Pepto-Bismol. However, blood alone is not diagnostic of colon cancer. A proper evaluation, including an exam, colonoscopy, blood tests, and imaging, is necessary to understand the cause.
Thanks
