Squamous Cell Carcinoma (SCC) – 10% of all skin cancers.
The majority of SCCs are due to exposure to ultraviolet radiation, which damages the DNA. They are particularly common in fair-skinned people.
Squamous cell carcinoma (SCC) is the second most common type of non-melanoma skin cancer. It is caused by squamous cells, the flat cells that make up the outside layers of the skin, also known as the epidermis. These cells are keratinising. This means they produce keratin, the protein that makes up skin, hair and nails.
Invasive SCC refers to cancer cells that have grown into the deeper layers of the skin, which is also called the dermis. Invasive SCC can, in rare cases, metastasize, or spread to other tissues. In these cases, if not caught and treated, there is the potential for SCCs to be fatal.
