Soft Tissue Sarcoma in Dogs
Soft Tissue Sarcoma is a medium-severity cancer condition that can affect dogs of all ages and breeds. Soft tissue sarcomas are a heterogeneous group of malignant tumours arising from connective tissues. They typically form firm subcutaneous masses that invade locally but metastasise relatively late. Grade determines biological behaviour. It is documented across 4 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 8-12 years. Early signs to watch for include firm subcutaneous mass, rapid growth, ulceration of overlying skin, and local tissue invasion. When treatment is required, costs are estimated at £2,500-£8,000 depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
Signs & Symptoms
The following symptoms are commonly associated with Soft Tissue Sarcoma in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.
- Firm subcutaneous mass
- Rapid growth
- Ulceration of overlying skin
- Local tissue invasion
- Occasional lameness if in limb
Treatment Overview
Wide surgical excision with histologically confirmed margins is the gold standard. Radiation therapy reduces local recurrence rates for incompletely excised high-grade tumours. Chemotherapy is considered for high-grade metastatic cases.
Typical onset: 8-12 years
Prevention & Screening
While not all cases of Soft Tissue Sarcoma can be prevented, the following steps reduce risk or enable earlier intervention:
- No proven prevention
- Early surgical biopsy and excision of growing subcutaneous masses
Estimated Treatment Cost
Treatment for Soft Tissue Sarcoma is estimated at £2,500-£8,000, depending on severity, the specific intervention required, and your location. Costs may be higher for surgical procedures or ongoing management. Comprehensive pet insurance covering this condition is strongly recommended.
