I Found a Lump on My Dog: What Do I Do?

Blog Summary

Finding a lump on a dog is understandably concerning, but not every growth signals a serious problem. Some masses, such as lipomas, sebaceous cysts, and skin tags, are typically benign, while others including mast cell tumors, soft tissue sarcomas, or enlarged lymph nodes may require advanced evaluation. The blog emphasizes the importance of timely veterinary assessment to distinguish between harmless and potentially malignant conditions.

Veterinary Specialty Center in Bannockburn, IL, provides specialized diagnostics and treatment for dogs with abnormal growths. Their team uses fine needle aspirates, biopsies with histopathology, and advanced imaging such as ultrasound, CT, and MRI to accurately identify the nature of a mass. Collaboration with primary veterinarians ensures that pet owners receive clear answers and carefully considered recommendations.

The article also explains when referral to a specialist is beneficial, particularly in cases requiring complex surgery, oncology expertise, or advanced imaging. With personalized care plans and seamless communication, Veterinary Specialty Center supports both pet owners and family veterinarians, offering reassurance and guidance throughout the diagnostic and treatment journey.

Introduction:

When a pet owner discovers an unfamiliar lump or growth on their beloved canine companion, it’s natural for concern to arise. While many dermal or subcutaneous masses prove to be benign, others necessitate prompt and thorough investigation by a veterinary specialist. Timely and precise evaluation is paramount to accurately characterize the growth and determine the optimal course of action.

At Veterinary Specialty Center in Bannockburn, IL, our dedicated team collaborates closely with referring veterinarians and pet owners to meticulously assess abnormal growths, offering advanced diagnostic and therapeutic interventions. If your primary veterinarian has referred your dog for further evaluation of a detected mass, understanding our approach can provide considerable reassurance.

Understanding Canine Cutaneous and Subcutaneous Masses

Lumps and masses in dogs present with diverse appearances and behaviors. Distinguishing between benign and potentially malignant lesions is a critical first step, often requiring specialized diagnostic techniques.

Common Benign Growths

Benign masses are non-cancerous and typically do not metastasize or pose a significant health threat. Frequently encountered benign lesions include:

• Lipomas: These are soft, movable, fatty tumors located subcutaneously, often seen in older or overweight dogs. While generally harmless, large lipomas can sometimes interfere with mobility or become irritated, necessitating removal.
• Sebaceous Cysts: Resulting from blocked oil glands, these appear as discrete, round nodules. They may spontaneously rupture and drain but usually resolve without aggressive intervention unless persistently inflamed or infected.
• Warts and Skin Tags: These small, superficial skin growths are typically innocuous. However, their removal may be warranted if they become irritated, bleed, or are located in areas prone to friction.

Even when a mass appears overtly benign, definitive diagnosis via veterinary assessment is crucial to exclude more serious underlying conditions.

Growths Requiring Further Evaluation

Certain masses warrant comprehensive diagnostic evaluation due to their potential for malignancy, local invasiveness, or association with systemic disease. These may include:

• Mast Cell Tumors: These highly variable tumors can appear in various sizes and presentations, sometimes exhibiting inflammation or pruritus. Their unpredictable biological behavior necessitates specialized diagnostic and treatment protocols due to their potential for local recurrence and metastasis.
• Soft Tissue Sarcomas: Characterized as firm, often slow-growing masses, soft tissue sarcomas can be locally invasive, extending into surrounding fascial planes and muscle. Early and complete surgical excision is often the primary treatment.
• Enlarged Lymph Nodes: While sometimes indicative of localized infection or immune response, persistent or significantly enlarged lymph nodes can signal more serious systemic conditions, including lymphoma or metastatic disease from other primary tumors.

Any growth exhibiting rapid enlargement, changes in texture, ulceration, or causing apparent discomfort should be promptly evaluated through advanced diagnostic testing.

When a Referral to a Specialist is Recommended

Your primary care veterinarian may recommend a referral to Veterinary Specialty Center if:

• The mass presents diagnostic ambiguity with routine methodologies.
• Advanced imaging modalities (e.g., ultrasound, CT, MRI) or specialized tissue sampling techniques are indicated.
• The mass necessitates complex surgical removal requiring the expertise or specialized instrumentation of a board-certified surgeon.
• A confirmed or suspected diagnosis of cancer warrants the consultation and management of a veterinary oncologist.

As a multi-specialty referral hospital, we emphasize a collaborative approach, working synergistically with your family veterinarian to ensure seamless diagnostic progression and therapeutic management.

Our Diagnostic Approach to a Canine Mass

Specialized diagnostic procedures enable a comprehensive understanding of a mass’s origin, biological behavior, and potential systemic impact. These insights are fundamental to formulating precise treatment recommendations.

Fine Needle Aspirate (FNA)

A fine needle aspirate involves using a small-gauge needle to collect a sample of cells from the mass. This minimally invasive, rapid procedure is often the initial diagnostic step, providing preliminary differentiation between inflammatory, benign, and potentially malignant cell populations. Depending on the cytological findings, further, more definitive testing may be indicated.

Biopsy and Histopathology

For a conclusive diagnosis, a tissue biopsy is often performed. This can range from an incisional biopsy (sampling a portion of the mass) to an excisional biopsy (removing the entire mass). The collected tissue is then meticulously examined by a veterinary pathologist (histopathology) to definitively diagnose the mass type, assess its margins, and predict its biological behavior, including the likelihood of recurrence or metastasis.

Advanced Imaging

When assessing internal masses, determining the extent of local invasion, or staging neoplastic disease, our diagnostic imaging team may utilize advanced modalities such as ultrasound, computed tomography (CT), or magnetic resonance imaging (MRI). These sophisticated tools are invaluable for precise surgical planning and comprehensive oncologic staging.
