Squamous cell carcinoma on a cat's nose

Squamous cell carcinoma can affect lightly pigmented, sun-exposed skin, including parts of a cat's face. A concerning area may begin as redness, scale, a sore, or a crust that returns after it is disturbed. Infection, trauma, allergies, and other growths can look similar. Because the nose is delicate and a cat may lick or scratch it, visual inspection alone is not enough; a veterinarian may need a sample and a full examination.

Arrange a veterinary appointment promptly when a nose lesion persists, enlarges, bleeds, or changes shape. Keep the cat from rubbing the area if possible, and do not use human creams, antiseptics, pain medicines, or home wart products unless the veterinarian specifically approves them. Take a clear photo for comparison and mention sun exposure, appetite, breathing, and any discharge. Veterinary treatment may include surgery or another cancer plan chosen for the lesion's depth and location; human pages on Surgical Excision and Mohs Surgery are not substitutes for veterinary advice.

Seek same-day veterinary care for uncontrolled bleeding, severe pain, marked swelling, pus, difficulty eating, or breathing changes. A cat that is unusually quiet, stops eating, or repeatedly paws at the face also needs prompt attention. Do not wait for a lesion to become large before arranging an examination.

Ask whether the lesion needs a biopsy, how pain and licking will be managed, and what treatment choices fit its position on the nose. Ask about sun avoidance, follow-up checks, and signs that should trigger an earlier return.
