Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts .
There is a risk of metastasis starting more than 10 years [citation needed] after diagnosable appearance of squamous-cell carcinoma, but the risk is low, [specify] though much [specify] higher than with basal-cell carcinoma. Squamous-cell cancers of the lip and ears have high rates of local recurrence and distant metastasis. [27]
Dermatoscopy may be useful in diagnosing basal cell carcinoma in addition to skin inspection. [42] There is insufficient evidence that optical coherence tomography (OCT) is useful in diagnosing melanoma or squamous cell carcinoma. OCT may have a role in diagnosing basal cell carcinoma but more data is needed to support this. [43]

D. Squamous cell carcinoma, infiltrating the stroma (middle and left in image), and HSIL (right in image) Epithelial dysplasia , a term becoming increasingly referred to as intraepithelial neoplasia , is the sum of various disturbances of epithelial proliferation and differentiation as seen microscopically.
Laryngeal cancer may spread by: direct extension to adjacent structures, metastasis to regional cervical lymph nodes, or via the blood stream. The most common site of distant metastases is the lung. Laryngeal cancer occurred in 177,000 people in 2018, and resulted in 94,800 deaths (an increase from 76,000 deaths in 1990).
About 5.4 million basal and squamous cell cancers (the two most common types of skin cancer) are diagnosed each year in the U.S., and about 80% of those are basal cell cancers, the American Cancer ...
