Mass Removals

Mass removals are a type of veterinary surgery commonly conducted at Sploot.

A “mass” refers to a lump under a pet’s skin. For both dogs and cats, masses can be benign or malignant. Our experienced vets will be able to detect and classify any masses that your pet may have.

At Sploot, we have experienced vets, a dedicated staff, and state-of-the-art facilities to ensure that all surgeries are carried out successfully and safely.

Why Pets Get Masses

There are numerous types of masses a pet can get. Lumps can be caused by blockages in the hair follicle, bacterial infections, non-cancerous growths, or cancerous growths.

Although dogs and cats can develop masses at any age, some types of masses (i.e. non-cancerous fatty lumps or lipomas) are more common in older pets. Malignant lumps also have an increased prevalence in older pets.

Factors like diet, lifestyle, and genetics also play a role in whether or not a pet develops malignant or cancerous masses.

Identifying Benign vs. Malignant Masses

Typically, pet parents may feel unusual masses on their pet’s skin or deeper in the subcutaneous layer.

Fatty lumps or lipomas (which are non-cancerous) are usually:

Round, oval, or bulging lumps
Freely Movable
Soft and squishy

Sebaceous cysts (which are non-cancerous) are usually:

Small, raised, and round bump (wart-like growth)
Movable
Hard or fluid-filled

Abscesses (which are not cancerous by themselves but can be a sign of cancer) are usually:

Swollen, pus-filled lumps
Movable (if the abscess does not involve deeper tissue)
Soft or a bit firm

Cancerous or malignant masses are usually:

Can take on various appearances
Immovable
Firm or hard to the touch


In some cases, benign (non-cancerous) and malignant (cancerous) masses can look and feel the same; the only way to tell the difference is by examining masses from a cellular level. It is always recommended to consult a veterinarian.

Why Mass Removal is Done

Address Discomfort or Malignancy
Veterinarians generally remove masses because of discomfort and/or malignancy. Veterinarians will be able to detect malignancy based on a cytological (cellular) examination of a sample collected through fine needle aspiration, which is done before recommending surgery.

Get a Conclusive Diagnosis
After a dog or cat undergoes mass removal surgery, the masses will undergo further histopathological (tissue) examination. This is the only way to conclusively diagnose a pet’s mass and determine the next steps in terms of needed care.

Preparing for Mass Removal Surgery: What to Expect

Before the Operation

Your pet will undergo a pre-operative appointment which includes the following:
01
A full physical exam is done (including blood work) to ensure your pet is medically fit for surgery.
02
Imaging tests may be used to see the location and extent of the masses.
03
You will be given instructions about when to start withholding food from your pet on the night before the surgery. (However, you can always give your pet water, regardless of the time.)
04
We will walk you through the procedure and post-operative care that your pet may need.

During the Operation

After dropping off your pet on the day of the surgery, they will stay with us until the procedure is completed and they’ve recovered from the anesthesia.
Through the entire procedure, our team will send live updates including texts with videos and photos for your peace of mind.

After the Operation

We will let you know when it’s time to pick up your pet. Before you go home, we will review the post-operative treatment plan with you and provide any medications your pet will need.

FREQUENTLY ASKED QUESTIONS

How long do mass removal surgeries take?

Mass removals can take a few minutes to over an hour depending on the extent and the depth of the masses.

Does my pet need a pre-surgical consultation?

Yes. A pre-op appointment is a vital first step to ensure that masses are removed successfully and safely. During this appointment, the veterinarian will assess your pet’s health, locate the masses, and suggest the next steps. If surgery is recommended, the veterinarian will also assess if your pet is safe to undergo surgery. During the pre-surgical consultation, the veterinarian will also orient you regarding the procedure and the needed post–operative care for your pet.

Does mass removal surgery have any complications?

There are rare instances that complications may arise after mass removal surgery because all types of surgery have potential complications. In case you observe any unusual changes in your pet’s behavior or on the site of the surgery (e.g. swelling, discharge), our team is always here to answer your questions and recommend next steps.
