Squamous cell carcinoma arises from the stratified squamous epithelium.

食管鳞起源于复层鳞状上皮。

Squamous cell carcinoma, as you can tell by its name, arises from squamous epithelium.

鳞状细（鳞）正如其名，来源于鳞状上皮细。

Wearing sunscreen helps protect against the development of all three types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.

基底细、鳞状上皮、和黑色素。

While the prognosis of squamous cell carcinoma in the oral cavity depends largely on the tumor stage, HPV status is a main prognostic factor for squamous cell carcinoma in the oropharynx.

腔鳞状细预后，很大程度取决于肿分期，而感染HPV状况则是鳞状细一个主要预后因素。

This cancer can appear in any segment of the esophagus and it's further classified into squamous cell carcinoma and adenocarcinoma - depending on the type of cells it originates from.

这种肿在食管任何节段都有可能出现，基于肿来源细类型，食管可以进一步被分为鳞状细与腺。

Now, squamous cell carcinoma is the most common type of esophageal cancer worldwide, and it originates in the squamous epithelium of the esophagus, most often in the upper two thirds.

鳞是世界上最常见食管类型，来源于食管鳞状上皮层，最常见于食管上三分之二。

Squamous cell carcinoma is also known to arise at the lip vermillion in those who smoke, right at the location where a person holds the smoking device, such as a cigarette or pipe.

研究发现，鳞状细也可发生于吸烟者唇红，位恰在吸烟者叼着烟具（如香烟或烟斗）地方。

Specific risk factors for squamous cell carcinoma include alcohol consumption, hot fluids and caustic strictures, which is the narrowing of the esophagus following ingestion of a caustic substance, like household bleach.

而鳞特有危险因素包括饮酒、高温液体与腐蚀性食管狭窄，即摄入腐蚀性液体（如家用漂白剂）后导致食管狭窄。

Over time, just like with squamous cell carcinoma, mutations might accumulate in either tumor suppressor genes or proto-oncogenes that control the division of these metaplastic cells, ultimately resulting in a malignant tumor.

长此以往，和食管鳞一样，抑基因和原基因会积累一系列突变，那些控制着化生细细周期基因突变最终会导致恶性肿。
