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]
The mortality rate of basal-cell and squamous-cell carcinoma is around 0.3%, causing 2000 deaths per year in the US. In comparison, the mortality rate of melanoma is 15–20% and it causes 6500 deaths per year.
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 .
According to the American Academy of Dermatology, the two most common types of skin cancers are basal cell carcinoma, squamous cell carcinoma. Skin cancer is usually caused by exposure to UV rays ...
Squamous-cell carcinoma of the skin is generally distinguishable by for example relatively more cytoplasm, horn cyst formation and absence of palisading and cleft formations. Yet, a high prevalence means a relatively high incidence of borderline cases, such as basal-cell carcinoma with squamous cell metaplasia (H&E stain at left in image).
Basal cells have important health implications since the most common types of skin cancer are basal cell and squamous cell carcinomas. More than 1 million instances of these cancers, referred to as non-melanoma skin cancers (NMSC) are expected to be diagnosed in the United States each year, and the incidence is rapidly increasing.
Basal cell carcinoma account for approximately 8% of all vulvar cancers. It typically affects women in the 7th and 8th decade of life. [22] These tend to be slow-growing lesions on the labia majora but can occur anywhere on the vulva. Their behavior is similar to basal cell cancers in other locations.
