Almost a quarter million of Americans will develop squamous cell cancer each year. Just as with basal cell cancer, it occurs most commonly on sun exposed areas. In a small percentage of cases, the tumor spreads (metastasizes) to other tissue and vital organs and can be deadly. High risk areas are most often in areas of chronic inflammation and mucous membranes. They can be completely and easily cured when treated early.
Just as with Basal cell cancer, squamous cell cancer can present in a variety of ways including a scaly red patch that may bleed, a non-healing ulcer that may or may not bleed, or a crusted wart-like growth that may bleed.
