PetA biopsy is how a vet finds out what a lump, skin lesion, or internal mass actually is — most importantly, whether it's cancer. The cost depends heavily on how the sample is taken and whether anaesthesia is needed. Here's the realistic Canadian breakdown, from a quick in-clinic aspirate to full surgical removal.
What it costs in Canada
| Scenario | Typical cost (CAD) |
|---|---|
| Fine-needle aspirate + cytology | Lowest — often the first step |
| Punch / incisional biopsy (local or sedation) | Roughly $300–$900 |
| Surgical (excisional) biopsy under anaesthesia | Roughly $1,000–$2,500+ |
| Histopathology lab analysis | Moderate — sometimes billed separately |
| Anaesthesia and monitoring (surgical) | A large share of a surgical biopsy |
| Internal / image-guided biopsy | Higher — specialist and imaging involved |
| Special stains or rush processing | Added on for some cases |
Vets usually start with the cheapest diagnostic that could answer the question — often a fine-needle aspirate — and escalate to a surgical biopsy only if needed. Always ask whether the lab histopathology fee is included in the quote, because it's a common surprise add-on. If a mass is removed and sent for analysis in one step, you're paying for the surgery and the diagnosis together.
With insurance vs paying out of pocket
| Scenario | You pay | Insurer pays |
|---|---|---|
| No insurance | Full sampling, anaesthesia, and lab fees | $0 |
| Comprehensive policy (illness work-up) | Annual deductible + your reimbursement share | Reimburses 70–90% of diagnostics after deductible |
| Comprehensive policy (mass already noted pre-enrolment) | Full cost | $0 — pre-existing exclusion |
| Wellness add-on only | Full cost — biopsies are diagnostic, not preventive | $0 from wellness portion |
Does a biopsy cost vary by city?
Less than most procedures. The part that's the same everywhere is the lab: histopathology is sent to a central veterinary laboratory (the large national labs serve the whole country), so the pathology fee is essentially flat nationwide. What shifts a little by location is the exam and sample-collection fee — a bit higher in major metros (Toronto, Vancouver, Calgary, Ottawa, Montreal) — and whether a specialist is involved.
Where geography does matter is the method: a simple needle aspirate can be taken at almost any clinic, but an ultrasound- or surgically-guided biopsy of an internal mass may need imaging equipment or an internal-medicine specialist, which are concentrated in larger centres. For a straightforward external lump, though, your regular vet anywhere in Canada can sample it and send it to the same lab.

What to ask before you agree
These are billing and planning questions, not medical ones. Treatment decisions belong with your veterinarian.
Considering insurance?
A biopsy is usually the gateway to a much bigger bill — if it comes back as cancer, treatment can run into five figures. Comprehensive coverage pays for the diagnosis and what follows, as long as the lump wasn't already noted before you enrolled. That pre-existing trap is exactly why enrolling early matters. Compare Canadian insurers before you find the lump.
