Which type of skin cancer is referred to as squamous cell carcinoma?

Squamous cell carcinoma (SCC) is a type of skin cancer that originates in the squamous cells, which are flat cells found in the outer layer of the skin (epidermis) and in some other parts of the body. This cancer typically arises in areas of the skin that are frequently exposed to the sun, such as the face, ears, neck, and backs of the hands, as well as in other locations such as the mouth or genitals.

SCC is significant due to its potential to invade deeper layers of skin and metastasize to other parts of the body if not treated in time. The presentation of SCC can vary but often includes a persistent, scaly red patch, an open sore, or a wart-like growth. Early identification and treatment are crucial, which can range from topical treatments to surgical removal, depending on the size and location of the tumor.

Understanding this context allows for a better appreciation of the aggressive nature of SCC, how it differs from other forms of skin cancer, and the importance of regular skin examinations to catch such malignancies early. Malignant melanoma, basal cell carcinoma (BCC), and actinic keratosis, while also related to skin health, represent distinct pathologies within dermatology.
