Soft Tissue Mass Removal - Fact Sheet

What is Soft Tissue Mass Removal?

Soft tissue mass removal is a surgical procedure to remove lumps or growths found on or just beneath the skin.

These masses may include benign cysts, lipomas (fatty lumps), or other types of growths requiring further analysis.

 

Important: This procedure is for skin and subcutaneous masses only. Masses located internally (e.g., spleen,

liver, chest cavity) require a different, more complex surgery. Your veterinarian will advise if this applies to your pet.

 

Understanding Lumps on Your Pet

Not all lumps are created equal — some are harmless, while others need attention. Here’s how we distinguish between minor and major lumps, and what it might mean for your pet.

Minor Lumps

These are generally smaller, softer, and less concerning lumps that we often monitor or remove for comfort or peace of mind.

Clinical Features:

  • Less than 2 cm in size (about the size of a pea)

  • Soft, movable, and located just under the skin

  • No ulceration, bleeding, or signs of infection

  • Not interfering with your pet’s movement or comfort

  • Often benign — like small lipomas or blocked glands

Major Lumps

These are larger or more complex lumps that warrant closer investigation and often surgical removal.

Clinical Features:

  • More than 2 cm in size (grape-sized or bigger), or growing quickly

  • Firm, deep, or fixed to underlying tissue

  • May be ulcerated, bleeding, or painful

  • Located in a high-risk area (e.g., near joints, mammary glands)

  • Has recurred or is one of multiple lumps

 

What to Expect

Before Surgery

A full pre-anaesthetic assessment is performed to ensure your pet's safety. For senior pets (over 10

years old, or over 7 years for large breeds) and for high-risk patients, pre-anaesthetic bloodwork

and IV fluids are mandatory. This helps detect hidden health issues and supports a safer

anaesthetic experience. Learn more about our anaesthesia protocols here.

During Surgery

Your pet will undergo general anaesthesia. Up to three skin or subcutaneous masses (one major maximum) will be

surgically removed. Stitches are used to close the incision, and samples may be sent for laboratory testing

if recommended.

After Surgery

Most pets return home the same day. Recovery involves rest, restricted activity, and monitoring the surgical site. We

will provide pain relief and, if needed, antibiotics. A follow-up appointment is needed to check healing and remove

sutures if required.

 

Key Information

  • This procedure is for skin and subcutaneous mass removals only.
  • Internal mass removals require a separate surgical plan and cost estimate.
  • Costs may vary depending on mass number, size, patient factors, anaesthetic needs, or unexpected findings.
  • Pre-anaesthetic bloodwork and IV fluids are mandatory for senior and high-risk patients and recommended for others.
  • Final costs may change depending on the individual case needs.
