What does blood in stool indicate 4 months after a Colonoscopy with clear results?

I had a colonoscopy done 4 months ago and everything was clear. However, yesterday I noticed a small amount of blood in my stool. The reason why I had the colonoscopy in the first place was having to pass unusually large stools at times – could this be the reason for the bleeding? As my colonoscopy was clear, is it likely that colon cancer could have developed in just 4 months?

Hemorrhoids is the most common cause.

Most likely hemorrhoids. It is very unlikely that colon cancer would develop in such a short time.
