Understanding Pet Lumps and Bumps: A Comprehensive Guide for Fairfax Pet Owners
Discovering a new lump or bump on your pet can be alarming. While some are harmless, others may require veterinary attention. Understanding the different types of lumps, how to monitor them, and when to seek professional evaluation is essential for maintaining your pet’s health. At Fairfax Veterinary Clinic, we provide expert care to assess, diagnose, and treat abnormal growths, ensuring the best possible outcome for your pet.
Common Causes of Lumps and Bumps in Pets
Pets, like humans, can develop skin and subcutaneous (under-the-skin) growths that range from harmless cysts to serious tumors. These growths can be benign (non-cancerous) or malignant (cancerous), with common types including:
- Cysts – Fluid-filled sacs caused by blocked hair follicles or glands, often benign but sometimes prone to infection.
- Lipomas – Soft, fatty tumors commonly found in older or overweight pets; usually harmless but can grow large enough to cause discomfort.
- Abscesses – Painful pus-filled swellings caused by infections from bites, scratches, or foreign objects.
- Warts (Papillomas) – Small, rough growths often found in younger dogs, caused by a virus.
- Histiocytomas – Benign skin tumors seen in young dogs, usually resolving on their own.
- Lymph Node Swelling – Enlarged lymph nodes may indicate infection, immune disorders, or even cancer.
- Mast Cell Tumors (MCTs) – One of the most common skin cancers in dogs, these can be highly aggressive and require immediate evaluation.
Regularly checking your pet for new growths can help with early detection and treatment.
How to Check Your Pet for Lumps and Bumps
Routine lump checks should be part of your pet’s monthly health routine. Here’s how to perform a thorough examination:
- Create a calm environment. Choose a quiet time when your pet is relaxed.
- Visually inspect your pet’s skin. Look for redness, swelling, or unusual bumps.
- Use your hands to feel for lumps. Gently run your fingers along their body, including under the belly, around joints, and in the armpits.
- Check lymph nodes. Palpate behind the jaw, in front of the shoulders, and behind the knees for swelling.
- Monitor changes. Keep a record of any new lumps, noting their size, shape, and consistency.

When Should You Be Concerned About a Lump?
Not all lumps require immediate veterinary attention, but certain signs warrant a professional evaluation:
- Rapid growth – A lump that doubles in size within a few weeks could indicate malignancy.
- Firm, fixed lumps – Growths that don’t move under the skin can be more concerning than soft, movable lumps.
- Discoloration or ulceration – Red, inflamed, or bleeding lumps may be infected or cancerous.
- Lumps in the mouth or near lymph nodes – These require immediate assessment as they may indicate oral tumors or systemic illness.
- Pain or sensitivity – If your pet reacts when a lump is touched, it could be infected or pressing on a nerve.
For more details on when a lump is an emergency, refer to AAHA’s Emergency Pet Guide.
How Veterinarians Diagnose Lumps and Bumps
At Fairfax Veterinary Clinic, we use advanced diagnostic tools to accurately assess lumps:
- Fine Needle Aspiration (FNA) – A small sample of cells is extracted using a needle and examined under a microscope.
- Biopsy – A tissue sample is surgically removed for a more detailed analysis.
- X-rays & Ultrasound – Used to assess deeper lumps and detect potential internal spread.
- Bloodwork & Lymph Node Evaluation – Helps determine if the immune system is reacting to infection or cancer.
These tests allow us to distinguish between benign and malignant growths, guiding the best course of treatment. Learn more about our diagnostic services on the Our Team page.
Treatment Options for Lumps and Bumps in Pets
Treatment varies based on the type, location, and severity of the lump:
- Monitoring – Some benign growths, such as small lipomas, require regular monitoring rather than immediate removal.
- Surgical Removal – Recommended for malignant tumors, fast-growing lumps, or growths that cause discomfort.
- Medication & Drainage – Infected abscesses are often treated with antibiotics and drainage procedures.
- Cryotherapy – Freezing small benign tumors (like warts) to remove them non-invasively.
For cancerous tumors, additional treatments such as radiation or chemotherapy may be necessary. Early intervention significantly improves the prognosis. Visit the Veterinary Cancer Society’s Pet Owner Resources for more information on cancer treatment in pets.
Preventive Measures & Regular Check-Ups
Prevention and early detection are crucial for your pet’s health. Here’s how you can help:
- Schedule routine veterinary check-ups – Annual exams help detect subtle changes before they become serious.
- Maintain a balanced diet & exercise – A healthy weight reduces the risk of fatty tumors (lipomas) and promotes overall wellness.
- Perform monthly lump checks – Consistent monitoring ensures early detection of new growths.
