Testing a lump costs little: a fine needle aspirate with pathology is commonly a few hundred dollars. Simple removals at a general practice run roughly $500 to $2,000 including anaesthesia and histopathology. Proper cancer surgery with wide margins, reconstruction, or internal masses like splenic tumours commonly runs $2,000 to $8,000 or more.
| Option | Typical Australian range | Notes |
|---|---|---|
| Fine needle aspirate and cytology | $150 to $500 | The test that names the lump; sometimes done in consult |
| Simple skin lump removal | $500 to $2,000 | Includes anaesthesia; histopathology may be extra, insist on it |
| Wide margin tumour resection | $2,000 to $5,000 | Planned oncological surgery, often with advanced imaging first |
| Internal mass surgery (e.g. splenectomy) | $4,000 to $8,000+ | Often urgent; includes hospitalisation and transfusion readiness |
| Staging (CT, ultrasound, nodes) | $500 to $4,500 | Mapping spread before big decisions; ask what changes based on results |
Histopathology on the removed lump tells you whether the margins were clean, and it is the difference between finished and a false finish. Staging before major surgery answers whether the big operation can still achieve its goal. Owners are sometimes offered savings by skipping one or both. It is your call, but understand what the discount buys: a cheaper invoice and a blindfold.
Send the case, hear back from a surgeon with what they can do and what it costs, and only pay if you go ahead.
Send what your vet said and quoted. A veterinary surgeon reads it and comes back to you with what they can do and what it would cost, before you pay anything. A written second opinion is from $250.
Size, location and movement problems: a benign lump in an armpit can still cost a dog its stride. And occasionally cytology under calls a lump; removal with histopathology is the definitive answer when anything about the story does not fit.
Splenic masses bleed, sometimes suddenly, and the surgery itself can need blood on standby. It is a genuine cost, a genuine safety measure, and a sign the clinic quoting you understands the operation.
Commonly $150 to $500 including the pathologist's reading, and it is often done in the consult without sedation. It is the same procedure and roughly the same price for cats. The result is sometimes inconclusive, and the vet may suggest a second sample or going straight to removal, which is a reasonable next step rather than a sign anything was done wrong.
It is usually quoted as a separate line, commonly a few hundred dollars on top of the surgical fee, and some clinics bundle it. Ask before the day whether it is included. It is the only way to learn what the lump was and whether the margins were clean, so if a quote looks cheap, check that this line has not been quietly left out.
Not by as much as people expect. An incisional biopsy still needs sedation or anaesthesia, a surgical site and histopathology, so for a small, accessible skin lump it is often more sensible to remove the whole thing and send that to pathology. A biopsy earns its keep when the lump is large or awkwardly placed and the surgical plan would change depending on what it is. If you are being offered one or the other and are not sure why, send the quote and a surgeon will explain which makes sense for your pet.
