Lipomas are the most common canine cutaneous tumour. They are usually benign fatty growths under the skin, but they are not all the same cost to remove. This page covers the diagnostic difference between a simple lipoma and an infiltrative lipoma, plus the surgical cost for each.
How Lipomas Differ From Other Tumors
A lipoma is a benign proliferation of mature adipocytes (fat cells). It almost never metastasises and rarely comes back if removed cleanly. But its diagnostic and surgical spine is distinct from mast cell tumors, mammary tumors, or oral tumors:
| Lipoma variant | Frequency | Diagnostic path | Surgery |
|---|---|---|---|
| Simple subcutaneous lipoma | ~85% of canine lipomas | Soft, mobile, "doughy"; FNA-cytology confirms mature adipocytes | Small incision; primary closure; outpatient |
| Infiltrative lipoma | ~8% of canine lipomas | Firm, poorly demarcated; FNA shows atypical fat cells infiltrating muscle | Wide-margin excision into muscle; may need reconstructive closure |
| Liposarcoma (malignant) | <1% of canine lipomas | FNA shows atypical mitotic figures; chest X-ray for metastasis | Wide-margin (3 cm) + radiation backstop |
| Angiolipoma / spindle cell lipoma | ~5% | Variable cytology; behaves like simple lipoma if low mitotic figures | Standard excision |

The diagnostic and surgical contrast against other tumour sub-articles (mast cell, mammary, oral, eyelid) is why this page exists as a separate entity.
Cost Breakdown for Simple Subcutaneous Lipoma
A simple lipoma is the cheapest scenario in canine tumour removal. Typical 2026 itemised invoice:
| Item | Cost range |
|---|---|
| Vet consultation | $75–$110 |
| FNA cytology (in-house or lab) | $40–$120 |
| Pre-anesthetic bloodwork | $80–$180 |
| IV catheter + fluids | $60–$120 |
| Anesthesia (15–25 min) | $150–$250 |
| Surgical excision (single lump) | $200–$425 |
| Suture / closure materials | $30–$60 |
| Recovery / outpatient discharge | included or $50 |
| Post-op histopathology | $150–$280 |
| Pain medication (5–7 day course) | $20–$45 |
| E-collar | $15–$30 |
| Total | $830–$1,620 |
The total at the 50th percentile for a simple lipoma is ~$1,000, with hospital-bill data from CareCredit and Sustainable Vet supporting this. Per Pawlicy, simple lipoma procedures average $400–$700 in mid-tier cities, and the Vety 2026 price data puts the median at $500.
Cost Breakdown for Infiltrative Lipoma
Infiltrative lipomas invade muscle, fascia, or nerves. Surgery requires wide-margin excision into healthy tissue, longer anesthesia, often a reconstructive closure, and a board-certified surgeon for difficult anatomical locations.
| Item | Cost range |
|---|---|
| Vet consultation + surgical specialist referral | $150–$300 |
| Pre-op FNA done by internist | $80–$150 |
| Pre-anesthetic bloodwork | $80–$180 |
| Pre-op ultrasound (deep location) | $250–$450 |
| IV catheter + fluids | $60–$120 |
| Anesthesia (45–90 min) | $300–$550 |
| Wide-margin excision by specialist | $700–$1,400 |
| Reconstructive closure (flap) | $200–$450 |
| Surgical consumables + cautery | $90–$150 |
| Hospitalisation (1 night) | $250–$450 |
| Post-op histopathology with margins review | $250–$400 |
| Pain medication (10-day course) | $35–$70 |
| Recheck + suture removal | $80–$140 |
| Total | $2,525–$4,760 |
The 50th percentile for infiltrative lipoma surgery is ~$3,400 nationally, per Vety 2026, Pawlicy, and CareCredit clinical estimate data.
What Makes a Lipoma Removal More Expensive?
| Cost driver | Why it raises the bill |
|---|---|
| Size >5 cm diameter | Longer incision, more tissue handling |
| Infiltrative histology | Wide-margin instead of narrow-margin |
| Location near a joint, nerve, or sphincter | Specialist surgeon required (board-certified surgeon adds $400–$800) |
| Recurrence re-excision | Scar tissue complicates dissection |
| Dog weighs >90 lb (very large) | Anaesthesia and fluids scale with body weight |
| Tier-1 city (NYC, SF) | Surgical fee multiplier 60–80% above national median |

Not every lipoma needs surgery:
- Small (<2 cm) and not growing: monitor every 6–12 months.
- Diagnosed confidently by FNA: cytology showing mature adipocytes is reliable.
- Not bothering the dog: no rubbing, no ulceration, no functional interference.
- Cost-prohibitive for owner: conservative monitoring is safe for confirmed simple lipomas.

Frequently Asked Questions
How much is a simple lipoma removal? 2026 national median: ~$500 (range $250–$700). Total bill including FNA, anesthesia, and histopathology: ~$1,000.
How much is infiltrative lipoma removal? 2026 national median: ~$1,400 for the surgery; with specialist, reconstruction, and 1-night hospitalisation: ~$3,400 all-in.
Do I need a biopsy before removing a lipoma? FNA cytology is usually sufficient for simple lipomas. Histopathology is done on the removed specimen post-op. For infiltrative or rapidly-growing masses, incisional or punch biopsy is preferred.
Will a lipoma come back after removal? Simple lipomas rarely recur if removed with clear margins. Infiltrative lipomas recur in 30–50% of cases without adequate margins. Source: Pawlicy infiltrative lipoma data.
Is lipoma removal covered by pet insurance? Yes, as long as the lipoma is not pre-existing. Reimbursement typically 70–90% after deductible. Source: Embrace Pet MCT coverage, Progressive pet insurance cancer coverage.
Can I leave a lipoma alone? For confirmed simple lipomas not causing functional problems, yes. Infiltrative lipomas have a higher recurrence risk and warrant wider excision.
