The vast majority of skin cancers are basal cell carcinomas and squamous cell carcinomas. While malignant, these are unlikely to spread to other parts of the body if treated early. They may be locally disfiguring if not treated early. A small but significant number of skin cancers are malignant melanomas.

Too much UV radiation from the sun or sunbeds can damage the genetic material (the DNA) in your skin cells. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.

The other type of skin cancer, melanoma, is a potentially aggressive, life-threatening cancer. It can start in dark skin tissue, such as a mole or birthmark, as well as in normally pigmented skin.

What Are Basal and Squamous Cell Skin Cancers? Basal and squamous cell skin cancers are the most common types of skin cancer. They start in the top layer of skin (the epidermis), and are often related to sun exposure. Cancer starts when cells in the body begin to grow out of control.

Skin cancer usually develops in areas of the body that are exposed to sunlight, such as the face, the back of the neck, and the shoulders. Psoriasis is more likely to appear on the scalp or the skin of the joints, such as the knees or elbows.

Some actinic keratoses can turn into squamous cell skin cancer. Because of this, the lesions are often called precancer. They are not life-threatening. But if they are found and treated early, they do not have the chance to develop into skin cancer.
