A personal history of precancerous skin lesions.Sunburns in adulthood also are a risk factor. Having had one or more blistering sunburns as a child or teenager increases your risk of developing squamous cell carcinoma of the skin as an adult. People who use indoor tanning beds have an increased risk of squamous cell carcinoma of the skin. Spending lots of time in the sun - particularly if you don't cover your skin with clothing or sunblock - increases your risk of squamous cell carcinoma of the skin even more. Being exposed to UV light from the sun increases your risk of squamous cell carcinoma of the skin. If you have blond or red hair and light-colored eyes and you freckle or sunburn easily, you're much more likely to develop skin cancer, including squamous cell carcinoma, than is a person with darker skin. However, having less pigment (melanin) in your skin provides less protection from damaging UV radiation. Anyone, regardless of skin color, can get squamous cell carcinoma of the skin. Risk factorsįactors that may increase your risk of squamous cell carcinoma of the skin include:įair skin. This indicates that other factors may contribute to your risk of skin cancer, such as having a condition that weakens your immune system. Most of the DNA mutations in skin cells are caused by ultraviolet (UV) radiation found in sunlight and in commercial tanning lamps and tanning beds.īut sun exposure doesn't explain skin cancers that develop on skin not ordinarily exposed to sunlight. The mutations tell the squamous cells to grow out of control and to continue living when normal cells would die. A cell's DNA contains the instructions that tell a cell what to do. Squamous cell carcinoma of the skin occurs when the flat, thin squamous cells in the middle and outer layers of your skin develop changes (mutations) in their DNA. Melanoma, another type of skin cancer, arises in the pigment cells (melanocytes).
As new cells move upward, they become flattened squamous cells, where a skin cancer called squamous cell carcinoma can occur. One type of skin cancer called basal cell carcinoma begins in the basal cells, which make skin cells that continuously push older cells toward the surface. Skin cancer begins in the cells that make up the outer layer (epidermis) of your skin.
