1. What Is Soft Tissue Sarcoma in Cats?
Soft tissue sarcomas (STS) in cats are malignant tumors that originate in the connective tissues beneath the skin. These tissues include muscles, fat, blood vessels, and nerves. While these tumors tend to grow slowly, some can be aggressive and spread rapidly. Approximately 7% of all skin cancers in cats are soft tissue sarcomas.
Expanding on Soft Tissue Sarcomas:
Soft tissue sarcomas are more common in dogs, but they do occur in cats. These tumors often appear encapsulated, but they have tendrils or finger-like projections that can invade surrounding normal tissue. These tendrils can make it difficult to remove the entire growth through surgery. If any of the tendrils are left, there is a possibility that the soft tissue sarcoma will recur. Because of the difficulties, early detection and treatment are crucial for improving the prognosis for cats diagnosed with STS.
2. What Are the Different Types of Soft Tissue Sarcoma in Cats?
While the general term “soft tissue sarcoma” covers a range of tumors, here are four common types found in cats:
- Fibrosarcoma: A cancerous growth presenting as a mass on the body or leg.
- Injection-site sarcoma: A tumor that develops at the site of a vaccine injection (e.g., rabies or feline leukemia). These tend to be more aggressive.
- Liposarcoma: Rare tumors that originate in a cat’s fat tissue.
- Nerve Sheath Tumors: Tumors arising from the covering of a nerve, appearing as masses on a limb or the body. In rare cases, they can be painful and may even result in paralysis of the affected limb.
Expanding on Types of Soft Tissue Sarcoma:
Understanding the specific type of sarcoma is crucial for tailoring the treatment plan. For instance, injection-site sarcomas require a more aggressive approach due to their tendency to recur. Regular veterinary check-ups can help in early detection.
