Which statement correctly describes the most common nasal tumor in dogs and its treatment?

• A. Adenocarcinoma — Radiation therapy
• B. Adenocarcinoma — Surgery
• C. Osteosarcoma — Radiation therapy
• D. Lymphoma — Radiation therapy

Answer: (A)

Nasal tumors in dogs are most commonly adenocarcinomas, malignant tumors arising from the nasal mucosa that tend to invade locally. Because of the anatomy of the skull and the tumor’s invasive nature, complete surgical removal is often not feasible or curative. Radiation therapy is the treatment of choice because it provides effective local control, can reduce tumor burden, and helps relieve symptoms, improving quality of life. The other options describe tumors less typical for the nasal cavity or treatments that are not standard primary options for this tumor type (bone tumors like osteosarcoma are not the usual nasal tumor, and lymphoma is less commonly the primary nasal tumor and is usually treated with chemotherapy). Thus, adenocarcinoma together with radiation therapy best matches the common biology and management.
