Squamous cell cancers arise from squamous cells that undergo genetic mutations that either activate proto-oncogenes or inactivate tumor suppressor genes.

鳞细胞癌产于经历了基因突变的鳞细胞，基因突变可能激原癌基因、或使抑癌基因失。

For example, squamous cells are flat, which makes it easy for materials like oxygen to move across them to the other side.

例如，鳞细胞是扁平的，这使得像氧气这样的物质很容易通过它们移动到另边。

A second type of epithelium is non-keratinized stratified squamous epithelium, and it contains cells that don't produce much keratin, making this layer less tough.

第二种上皮是未角化的复层鳞上皮，其细胞产的角质较少，故这层结构相对比较脆弱。
