Gender linked to skin cancerInherent gender differences instead of more sun exposure may be one reason why men are three times more likely than women to develop certain kinds of skin cancer, say scientists at Ohio State University Medical Center.
Squamous cell carcinoma is the second most common form of skin cancer, accounting for nearly 200,000 new cases in the United States each year. While occurring more often than melanoma, squamous cell carcinoma is not nearly........Go to the Skin news blog (Added on 4/1/2007 9:10:23 PM)
