Rectal bleeding is the commonest symptom of hemorrhoids. It is also a presenting symptom of colorectal cancer. Those two facts are why this clinic examines bleeding instead of reassuring you about it.
The sentence that does the damage here is the dismissive one, the version where it is only piles and needs no further thought. Said early enough and confidently enough, that keeps people away from an examination for months at a time, and bleeding is the one symptom where those months really matter.
Every clinical source consulted for this site frames assessment rather than reassurance as the first step, and one explicitly warns against dismissing persistent bleeding. That is why an anoscopy happens at the first visit here rather than at the third.
Most of the time it does turn out to be hemorrhoids, and then we treat them. But the order matters: look first, then treat. The bleeding page covers what the examination is looking for, and the symptoms hub covers the conditions that present the same way.
Montreal safety
What happens
How bleeding is handled in Montreal
You describe it
Whether the blood sits on the surface or runs through the stool, how long it has gone on, and whether anything else changed.
We examine
An external look and an anoscopy. This is what separates a hemorrhoid from a fissure, and both from something else.
We screen the history
Age, family history of colorectal cancer, weight loss, change in stool habit, blood thinners. Any of these changes the plan.
Treat or refer
Either a procedure with a plan behind it, or a referral for a colonoscopy, said at that visit rather than later.
What we will not do
What we will not treat without looking further
Some findings move the question past this clinic, and when they are present a band is the wrong answer. Blood mixed through the stool rather than sitting on its surface, which the bleeding page goes into. Bleeding that has lasted beyond a week, or that keeps coming back. A change in the shape or frequency of your stool.
Also: unexplained weight loss, signs of anemia, black or tarry stools, severe abdominal pain, or fever alongside the bleeding. Heavy or continuous bleeding, clots, dizziness, fainting or a fast pulse are reasons for urgent care rather than an appointment.
And two that are about you rather than the symptom: being over forty-five or having a family history of colorectal cancer, and being on blood thinners. Neither rules out treatment, but both change what has to happen first. Referrals and conservative care cover what that looks like.

The questions worth asking before you decide this is nothing, and before anyone treats it.
Commonly, but commonly is not always. Bright red blood sitting on the surface of the stool or on the paper does point that way, which is a reason to get it examined rather than a reason not to.
That the source is likely higher up than a hemorrhoid, which moves the question away from this clinic. It is one of the findings that gets a colonoscopy rather than a band.
Bleeding that has lasted beyond a week, or that keeps returning after it seemed to stop, should be looked at. The exact threshold matters less than not letting months go by.
Yes. Being over forty-five, or having a family history of colorectal cancer, changes what has to happen before any procedure. It does not rule out treatment, it reorders it.
Heavy or continuous bleeding, clots, dizziness, fainting, a racing pulse, severe abdominal pain or fever alongside bleeding are reasons for urgent care now rather than an appointment later.
It does, both for how bleeding is interpreted and for what can safely be done about it. Tell us at the first visit, because it changes the screening and sometimes the choice of procedure.
Warning signs
Why this page exists at all
Assessed, not reassured
Every clinical source consulted puts assessment first. Reassurance before an examination is the thing this page is against.
Said at visit one
If what you have needs a colonoscopy or another specialty, you hear it at the first appointment, not the third.
The list is published
The findings that get a referral instead of a procedure are written down here, rather than left to a judgement call.
Months of cream is a flag
Treating unexamined bleeding for months is itself a warning sign, whoever suggested the cream.
An examination takes a couple of minutes and settles what months of guessing cannot. If it turns out to need someone else, you will be told that at the first visit.
