Skin cancer. Squamous cell carcinoma on a 73-year-old man's forearm. Squamous cells are flat scale-like cells in the upper layers of the skin. Squamous cell carcinoma is the second most common type of skin cancer. Most cases arise from pre-cancerous lesions known as solar keratoses, which are caused by sun damage. It mostly affects the elderly. Treatment is with surgical removal of the tumour, combined with radiation therapy and chemotherapy.
