Feline Nasal Tumours: Welfare and Radiation Therapy Outcomes

Nasal tumours in cats cause progressive facial destruction and respiratory distress, with radiation therapy offering the best welfare outcomes for a condition that is otherwise rapidly fatal.

Key Facts

Feline nasal tumours are predominantly carcinomas or lymphomas arising in the nasal cavity
Clinical signs include epistaxis, facial deformity, sneezing, and unilateral nasal discharge
CT imaging is essential for tumour staging and radiation therapy planning
Radiation therapy achieves median survival of 12-18 months in responsive cases
Palliative care without radiation typically results in death within weeks to months

Welfare Considerations

Feline nasal tumours cause progressive facial destruction, respiratory distress, and chronic discomfort as the tumour erodes nasal turbinates and potentially extends to the orbit or brain. Without treatment, rapid deterioration causes severe welfare compromise within weeks. Radiation therapy significantly extends periods of good quality life and provides local tumour control, though long-term cure is uncommon. Side effects from radiation including mucositis and skin inflammation cause temporary welfare compromise. Overall, radiation therapy provides a meaningful welfare improvement compared to palliative management alone for cats with good performance status.

What You Can Do

Seek CT imaging and specialist assessment promptly if your cat develops unilateral epistaxis or facial deformity
Discuss radiation therapy referral with your vet as the most effective welfare intervention available
Monitor for radiation side effects including mouth inflammation and skin reactions during treatment
Use validated feline quality of life assessment tools to monitor welfare throughout treatment
Plan proactively for euthanasia with your specialist when tumour progression causes unmanageable welfare compromise
