What Is Mass & Tumour Removal?
Mass and tumour removal involves the surgical excision of abnormal growths on or under your pet’s skin. These growths may be benign (non-cancerous) or malignant (cancerous), and the only way to determine their nature is through a veterinary exam and diagnostic testing, such as fine needle aspiration or biopsy.
While not all masses are dangerous, it’s important to monitor changes in size, shape, or behaviour. Early evaluation allows us to determine whether removal is necessary and the best time to perform surgery.
Why Mass & Tumour Removal Matters
Some masses are harmless and don’t require immediate treatment—but others may grow aggressively, cause discomfort, interfere with mobility, or pose serious health risks. Timely surgical removal can:
- Prevent malignant tumours from spreading to other areas
- Relieve pain or irritation caused by rapidly growing or ulcerated lumps
- Improve your pet’s comfort and quality of life
- Provide clarity and peace of mind through diagnostic testing
By taking action early, you can avoid complications and help your pet stay active and pain-free.

- Continuous vital sign monitoring throughout the procedure
- Complete removal of the mass, followed by closure with sutures or surgical glue
