Benign Tumours & Growths
Lipomas, sebaceous adenomas, histiocytomas, and other benign lumps commonly found in older dogs.
What is Benign Tumours & Growths?
Most lumps in senior dogs turn out to be benign — but you can't tell benign from malignant by feel or look alone. Common benign growths include lipomas (soft fatty masses), sebaceous adenomas (warty growths), histiocytomas (fast-appearing red buttons in young dogs), and skin tags.
Common signs and symptoms
Signs vary between dogs and can be subtle at first. Watch for the following, especially if several appear together or persist for more than a few days:
- Lipoma: soft, movable subcutaneous mass
- Sebaceous adenoma: warty, cauliflower-like small growth
- Histiocytoma: red, dome-shaped growth in young dogs, often self-resolves
- Skin tags: small, pedunculated growths
Risk factors
Certain dogs are more predisposed. Understanding risk helps you screen earlier and act sooner.
- Lipoma: overweight middle-aged dogs, Labrador, Doberman
- Sebaceous adenoma: senior dogs of many breeds
- Histiocytoma: dogs under 3
When to see a vet
Use this as general triage guidance, not a substitute for veterinary advice.
- Book a routine appointment if: get every new lump aspirated — a 60-second procedure spares months of anxiety and catches early cancers.
- Seek urgent care if: rapid growth, ulceration, or a lump interfering with movement.
Diagnosis and management
A confirmed benign lump can usually be monitored with periodic photos and measurements. Removal is considered when a lump interferes with function, is in a problematic location, or when the diagnosis is uncertain.
