| | Squamous cell cancer |
 | | Squamous cell carcinoma (SCC) accounts for the majority of non-small cell lung cancer, other bronchial tree cancers, and cancers arising throughout the upper aerodigestive tract including the oral cavity, paranasal sinuses, pharynx, larynx, trachea, and esophagus. |
 | | These common changes strongly suggest that initiation, development, and progression of squamous epithelial neoplasia are controlled by some of the same genetic pathways, irrespective of anatomic site. |
 | | A common sequence of SCC karyotype evolution appears to be initial loss of chromosomes or segments, followed by tetraploidization, and ultimately loss of previously uninvolved chromosomes from the tetraploid population. |
