Squamous cell cancer involves cancerous changes to the cells of the middle portion of the epidermal skin layer. It is a malignant tumor, and is more aggressive than basal cell cancer, but still may be relatively slow-growing. It is more likely than basal cell cancer to spread (metastasize) to other locations, including internal organs. Treatment usually involves surgical removal of the tumor along with some surrounding tissue.
