Which is a typical treatment for localized tumors in small animals?

Surgical excision is a typical treatment for localized tumors in small animals because it aims to remove the tumor along with a margin of surrounding healthy tissue. This approach is often curative for tumors that have not metastasized or invaded adjacent structures extensively. Successful surgical intervention can lead to the resolution of the disease and can provide the best chance for long-term survival, especially in cases where the tumor is well-defined and operable.

Radiation therapy, while it can be useful in certain circumstances to shrink tumors or as an adjunct to surgery, is generally not the primary treatment for localized tumors. It may be employed when surgery is not an option or when the tumor cannot be completely removed. Chemotherapy is primarily used for systemic tumor control, usually suited for cancers that have spread or are not localized. Palliative care focuses on improving quality of life without necessarily targeting tumor removal or control, making it inappropriate as a primary treatment for localized tumors.
