Which treatment plan is most appropriate for a cat diagnosed with mast cell tumor?

The most appropriate treatment plan for a cat diagnosed with a mast cell tumor is surgical removal of the tumor. Mast cell tumors in cats are commonly localized growths that can often be effectively managed through surgical excision. The goal of surgery is to remove both the tumor itself and a margin of healthy tissue surrounding it to reduce the risk of recurrence.

While radiation therapy and chemotherapy may be considered in some cases, particularly for tumors that are inoperable or for managing metastasis, surgical removal is typically the first line of treatment. Supportive care may be beneficial in improving the overall quality of life or treating associated symptoms, but it does not directly address the tumor itself.

In most instances, a comprehensive treatment plan for mast cell tumors starts with surgery, making it the primary choice in these situations.
