Most basal cell and squamous cell skin cancers are caused by repeated and unprotected skin exposure to ultraviolet (UV) rays from sunlight, as well as from man-made sources such as tanning beds. UV rays can damage the DNA inside skin cells.DNA is the chemical in each of our cells that makes up our genes.esearchers donât yet know all of the DNA changes that result in skin cancer, but they have found that in many skin cancers the cells have changes in tumor suppressor genes. The gene most often altered in squamous cell cancers is called TP53. This tumor suppressor gene normally causes cells with damaged DNA to die.
Squamous-cell carcinoma or squamous-cell cancer (SCC or SqCC) is a cancer of a kind of epithelial cell, the squamous cell.These cells are the main part of the epidermis of the skin, and this cancer is one of the major forms of skin cancer.CC is still sometimes referred to as  epidermoid carcinoma  and  squamous-cell epithelioma , though the use of these terms has decreased. SCC typically initially occurs in the sixth decade of life (the 50s), but is most common in the eighth decade (the 70s). It is twice as prevalent in men as in women.
