Squamous Cell Carcinoma Treatment in Dogs

This is a cancer of squamous cells, which form part of the skin and some body linings. A veterinarian may examine the growth and take a sample for laboratory diagnosis. The plan can differ for a surface lesion, a growth near the mouth, or a tumour involving a paw or nail bed. Staging may include checking nearby tissue and lymph nodes when the examination suggests deeper or wider disease.

Arrange a veterinary appointment promptly and avoid picking, squeezing, or applying human creams to the lesion. Bring notes about when it appeared, changes in its shape, bleeding, licking, or discomfort. Treatment may involve removal of the tumour with surrounding tissue; specialised surgery can be considered when preserving nearby healthy structures matters. Read about [Surgical Excision](/treatments/surgical-dermatology/excisional-surgery/) and [Skin Cancer Surgery](/treatments/surgical-dermatology/skin-cancer-surgery/) with your veterinary team in mind, since human dermatology procedures are not automatically suitable for animals.

Seek urgent veterinary advice if the growth is bleeding repeatedly, has an unpleasant discharge, becomes painful, or interferes with eating, walking, breathing, or normal activity. Rapid enlargement or a new lump near the original site also deserves prompt review. A wound that will not heal should be assessed even if your dog otherwise seems well.

Ask what sample is needed, whether imaging or lymph-node assessment is appropriate, which treatment fits the location, and how pain and wound care will be managed. Ask how the diagnosis changes the follow-up plan and what changes at home should trigger a call.
