Squamous Cell Carcinoma Overview

SCC occurs when DNA damage from exposure to ultraviolet radiation or other damaging agents trigger abnormal changes in the squamous cells. At times, SCCs may crust over, itch or bleed. SCCs can appear as scaly red patches, open sores, rough, thickened or wart-like skin, or raised growths with a central depression.

The lesions most commonly arise in sun-exposed areas of the body. If you see something new, changing or unusual on your skin, schedule an appointment with your dermatologist. Adding the word “cutaneous” identifies it as a skin cancer and differentiates it from squamous cell cancers that can arise inside the body, in places like the mouth, throat or lungs. SCCs can also occur in other areas of the body, including the genitals.

Please note: Since not all SCCs have the same appearance, these photos serve as general reference for what they can look like.

Squamous Cell Carcinoma Overview


p>Squamous cell carcinoma (SCC) of the skin is the second most common form of skin cancer, characterized by abnormal, accelerated growth of squamous cells. While the majority of SCCs can be easily and successfully treated, if allowed to grow, these lesions can become disfiguring, dangerous and even deadly. You can find more images, as well as signs, symptoms and early detection strategies on our SCC Warning Signs page.

SCCs look different on everyone. An open sore that bleeds or crusts and persists for weeks. A persistent, scaly red patch with irregular borders that sometimes crusts or bleeds.

One of three main types of cells in the top layer of the skin (the epidermis), squamous cells are flat cells located near the surface of the skin that shed continuously as new ones form. />An elevated growth with a central depression that occasionally bleeds. A wart-like growth that crusts and occasionally bleeds. Untreated SCCs can become invasive, grow into deeper layers of skin and spread to other parts of the body. It may rapidly increase in size. When caught early, most SCCs are curable.

SCC of the skin is also known as cutaneous squamous cell carcinoma (cSCC).
