Lumps and bumps are extremely common in dogs, particularly as they age. While many lumps are benign (such as lipomas), others may be cancerous and need prompt removal. Here is what lump removal surgery costs in the UK.

Average Lump Removal Costs

  • Small lump, straightforward location: £300 to £600
  • Medium lump or awkward location: £500 to £1,000
  • Large lump or wide surgical margins (cancer): £800 to £1,500+
  • Multiple lumps removed in one session: £500 to £1,500
  • Histopathology (lab analysis of the lump): £100 to £250 on top

These prices include the general anaesthetic, the surgery itself, and basic post-operative care. Histopathology is always recommended but may be quoted separately.

What Affects the Price

Size and Location

A small lipoma on the trunk is a 20–30 minute surgery. A large lump on the leg, near a joint, or in a surgically complex area takes longer and requires more skill. Lumps on the head, feet, or near the eyes may be especially complex.

Surgical Margins

If the lump is suspected to be cancerous (e.g. a mast cell tumour), the surgeon needs to remove a wide margin of healthy tissue around it — typically 2–3 cm in all directions. This creates a much larger wound, longer surgery, and sometimes requires skin flaps or grafts to close the wound, all adding to the cost.

Pre-Operative Tests

Your vet may recommend a fine needle aspirate (FNA) before surgery to help plan the procedure (£100–£250). Blood tests to check your dog is fit for anaesthetic may cost an additional £80–£150. Both are worthwhile investments.

Practice Type

Corporate-owned practices charge an average of 17% more than independent practices according to the CMA's 2025 findings. For a £700 lump removal, that difference could be over £100.

Why Histopathology Matters

Sending the removed lump to a laboratory for analysis (histopathology) costs £100–£250 but is strongly recommended. It tells you:

  • Exactly what the lump is
  • Whether it is benign or malignant
  • Whether the surgical margins are clean (the entire tumour was removed)
  • The grade (how aggressive the tumour is), which guides further treatment decisions

Skipping histopathology saves money upfront but could mean a cancer diagnosis is missed.

How to Save

  • Pet insurance: Lump removal is one of the most commonly claimed surgical procedures. Ensure your policy was in place before the lump appeared.
  • Act early: Small lumps are cheaper to remove than large ones. If your vet recommends removal, doing it sooner rather than later usually means a simpler, cheaper procedure.
  • Remove multiple lumps at once: If your dog has several lumps needing removal, having them done in a single surgery saves on anaesthetic costs.
  • Compare practices: Use VetCost to compare surgical prices at practices near you.
  • Discuss with your vet: Not every lump needs removing. Your vet can help you assess which lumps need urgent removal, which can be monitored, and which can safely be left alone.
