Oral tumours account for 6–7% of all canine cancers and are the fourth most common malignancy in dogs. Melanoma, squamous cell carcinoma, and fibrosarcoma are the three big ones. This page separates the cost spines for mandibulectomy, maxillectomy, and debulking surgery — three different procedures with very different bills.
Oral Tumour Types and Their Surgical Paths
| Tumour type | Common breed / age | Surgical option | Median cost (2026) | Notes |
|---|---|---|---|---|
| Malignant melanoma (oral) | Scottish Terrier, Cocker Spaniel, Chow; older dogs | Mandibulectomy or maxillectomy (radical) or debulking (palliative) | $2,000–$6,000 (radical); $1,200–$3,000 (palliative) | Melanoma vaccine adds $2,500–$4,000 if pursued post-op |
| Squamous cell carcinoma (SCC) | Pugs (oral SCC), older dogs | Mandibulectomy (rostral or total) | $2,500–$5,500 | Less aggressive than melanoma; better 1-yr survival |
| Fibrosarcoma (oral) | Large breeds, mid-age dogs | Maxillectomy (often partial) | $3,000–$6,000 | Locally invasive; often requires staged removal |
| Acanthomatous ameloblastoma (ACA) | Medium/large dogs | Mandibulectomy (rostral partial) | $2,000–$4,500 | Benign; locally invasive; excellent prognosis |
| Gingival hyperplasia | Boxer, Bulldog | Gingivectomy (small procedure) | $400–$900 | Not a malignancy; only included for reference |
| Epulis | Boxer, Bulldog | Surgical excision | $300–$700 | Benign; simple removal |

This page exists as separate page because oral tumours require a CT-based staging workup (mandatory before surgery to plan margins and rule out metastasis).
Mandatory Pre-Op Staging for Oral Tumours
| Test | Cost | Justification |
|---|---|---|
| Oral exam under general anesthesia (EUA) | $300–$500 | Visualisation of full oral cavity and biopsy site |
| Pre-anesthetic bloodwork + coagulation panel | $120–$220 | Surgical risk profile |
| Thoracoabdominal CT (mandatory) | $900–$1,500 | Pulmonary + lymph node + primary tumour extent |
| Incisional biopsy of oral mass (during EUA) | $300–$600 | Histologic confirmation before radical surgery |
| Dental radiographs of tumour area | $80–$180 | Mandibular/maxillary bone involvement |
| Lymph node FNA (mandibular + retropharyngeal) | $120–$200 | Regional staging |

Total pre-op cost range: $1,820–$3,200. This is significantly higher than for cutaneous tumours or even mammary tumours.
Cost Breakdown: Mandibulectomy (Partial or Total)
A partial mandibulectomy removes part of the lower jaw to provide 2–3 cm clean margins around the oral tumour. About 30% of dogs undergo this for malignant oral tumours.
| Step | Cost |
|---|---|
| Initial consult + surgical specialist consult | $250 |
| Pre-op EUA + biopsy + dental radiographs | $900 |
| Thoracoabdominal CT | $1,200 |
| Pre-anesthetic bloodwork | $180 |
| IV catheter + fluids | $100 |
| Anesthesia (2–3 hours) | $700 |
| Partial mandibulectomy (surgical excision) | $1,500 |
| Wound closure + flap (if needed) | $300 |
| Surgical consumables + high-speed drill | $250 |
| 2-night hospitalisation | $700 |
| Histopathology with margin review | $400 |
| Pain medication (10-day course) | $80 |
| Antibiotics (extended for oral surgery) | $60 |
| Soft food / feeding tube support | $50 |
| 14-day recheck | $90 |
| Total | $6,760–$8,560 |

50th percentile for partial mandibulectomy: $4,200 national average.
Cost Breakdown: Maxillectomy
Maxillectomy is more complex anatomically because the maxilla borders the orbit and nasal cavity. Often done by a board-certified veterinary dentist or surgeon.
| Step | Cost |
|---|---|
| Consult + surgical specialist consult | $300 |
| Pre-op EUA + biopsy | $900 |
| Thoracoabdominal CT | $1,400 |
| MRI (if any concern about sinus extension) | $1,800 |
| Pre-anesthetic bloodwork | $180 |
| Anesthesia (3+ hours) | $900 |
| Partial or total maxillectomy | $2,000 |
| Reconstructive flap (complex) | $500 |
| Surgical consumables + drill | $300 |
| 2-night hospitalisation in ICU | $1,000 |
| Histopathology with margin review | $400 |
| Pain medication (extended course) | $100 |
| Antibiotics | $80 |
| 14-day recheck | $100 |
| Total | $9,960–$11,960 |

50th percentile for maxillectomy in 2026: ~$6,000 national average.
Cost Breakdown: Palliative Debulking Surgery
When radical surgery isn't feasible (poor surgical candidate, owners decline, distal metastasis), debulking is palliative — removes most of the tumour mass to improve quality of life.
| Step | Cost |
|---|---|
| Consult | $200 |
| Pre-op workup (less aggressive than radical) | $400 |
| Anesthesia (90 min) | $450 |
| Debulking surgery | $700 |
| Tumour bed cautery | $150 |
| 1-night hospitalisation | $300 |
| Pain medication | $60 |
| Total | $2,260–$2,800 |

50th percentile for debulking: ~$1,900. Often paired with palliative radiation ($2,000–$5,000 for a 4-session course).

Read the tumor removal cost hub →The Melanoma Vaccine (Oncept) Add-On
If the histology confirms oral malignant melanoma and the dog has clean margins, the Oncept DNA melanoma vaccine may be recommended. Series: 4 doses, every 2 weeks.
| Item | Cost |
|---|---|
| Vaccine series (4 doses) | $2,500–$4,500 |
| Administration cost (some vets give subcutaneous) | $100–$300 |
| Total | $2,600–$4,800 |

Efficacy is debated, but it's commonly used as an adjunct after mandibulectomy/maxillectomy for melanoma.
What Makes Oral Tumour Surgery Cost More
| Cost driver | Why it raises the bill |
|---|---|
| Tumour crossing midline (requires bilateral maxillectomy) | Doubles surgical time |
| Tumour >4 cm (more aggressive margins) | Longer anesthesia, more reconstruction |
| Pre-op CT reveals metastasis | Surgery may be declined |
| Board-certified surgeon vs general practitioner | $400–$800 specialist-fee premium |
| Recurrence re-excision | Scar tissue + altered anatomy |

Compare pet insurance →Frequently Asked Questions
How much does oral tumor removal cost in dogs? 2026 range: $1,200 (palliative debulking) to $6,000+ (radical mandibulectomy) national median. Total including pre-op staging can reach $10,000+ for maxillectomy.
Is mandibulectomy well-tolerated? Yes. Most dogs eat, drink, and play normally after a few weeks of recovery. About 85–90% of owners describe their dog's quality of life as good or excellent post-op. Source: NC State VTH Mandibulectomy Outcomes.
Can oral tumors come back? Yes, especially melanoma (recurrence rate 30–60% even with clean margins). SCC has lower local recurrence (15–25%) but can metastasise to the lungs.
How long do dogs live after oral tumor removal?
- Melanoma: median 9–18 months with surgery ± vaccine
- SCC (with mandibulectomy): median 1–2 years
- Fibrosarcoma: median 6–12 months
Source: NC State VTH Outcomes, PetMD survival data.
Does pet insurance cover oral tumor surgery? Yes, if not pre-existing. Plans vary in chemotherapy coverage; most cover the main surgery but only some cover Oncept vaccine.
