Squamous cell carcinoma is a cancer of the outermost layer of skin cells. It can appear as a scaly or crusty patch of skin usually bigger than 1 cm (but may be smaller) that won’t heal.
Non-melanoma skin cancers usually develop on exposed body parts such as the face, neck, ears, forearms and hands, and are most common in older age groups.
You can find further information on non-melanoma on the NHS Choices website.
