It doesn’t get as much attention as other skin cancers, but squamous cell cancer is common and serious.
From the Harvard Health Letter, May 2006
Summer’s the season for fun in the sun—but also for skin cancer. Of the three main types of skin cancer, melanoma is most deadly, and basal cell, most common. Squamous cell cancer falls in between.
