What's That Spot? A Photo Guide to Skin Cancer

Squamous Cell Carcinoma

Squamous cell carcinoma is the second most common type of skin cancer and the second most aggressive. Squamous cells make up most of the epidermis and when cancerous they tend to destroy the surrounding tissue (which is why they can cause disfigurement too), but most cases aren't serious if they are found early enough.

Where you'll find it:
On the lower lip, the scalp, the rim of the ear and most other sun-exposed body parts. Plus, watch any areas where you've had burns, scars, sores, etc., because squamous cell carcinoma tends to develop in these weakened spots.
