Your cat was diagnosed with Cutaneous Squamous Cell Carcinoma (Non-Nasal). Second most common skin tumour in cats after mast cell tumour. Solar-induced (UV) aetiology in most cases. Progression from actinic keratosis → carcinoma in situ → invasive SCC. Most commonly affects pinna (ear tips), eyelids, and nasal planum but this entry covers non-nasal cutaneous sites. Predominantly affects white or light-pigmented cats in sun-exposed areas. Outdoor cats at higher risk. Compare 6 treatment options for cats including Surgical Excision, Radiation (Hypofractionated), Electrochemotherapy — with survival times, costs, and what to expect during treatment.

About This Cancer
Cutaneous squamous cell carcinoma at sites other than the nasal planum arises from the squamous cells of the skin. Like nasal planum SCC, it can be associated with ultraviolet radiation exposure in lightly pigmented cats, particularly affecting the ear tips and eyelids. The tumour is locally invasive but tends to have a low rate of distant metastasis when found in the skin. Early diagnosis and complete surgical removal offer the best outcomes, and most cats with fully excised cutaneous SCC do very well. Radiation therapy and electrochemotherapy are effective alternatives or adjuncts when surgery alone cannot achieve clean margins. With timely diagnosis and complete removal, the prognosis for cutaneous SCC at these sites is generally favourable.

Median Survival Time Comparison
How long the average patient survives with each treatment
Each treatment is rated by how much published research supports its use. Solid bars indicate stronger evidence; dashed bars mean less certainty.
Please note: All treatment data is sourced from published peer-reviewed literature. Survival times and cost figures are approximate guides. Your pet's individual factors — including tumour grade, stage, and overall health — will influence outcomes and should guide all treatment decisions. The strength-of-evidence rating reflects how much research exists, not how strongly a treatment is recommended. This tool is designed to help you have informed conversations with your veterinary oncologist, not to replace them. Costs shown are US referral centre estimates and may vary significantly by region.
