Skin cancer has become the most frequent type of human cancer. Basal-cell carcinoma and spindle cell carcinoma represent cutaneous epithelial carcinoma, the main risk factor being UV radiation (generated by either natural sources – sun or by artificial sources).
Basal-cell carcinoma is a cutaneous epithelial carcinoma with a very low malignancy level that does not or that very rarely metastasizes and that does not locate at the level of the mucous membranes.
One third of the total number of diagnosed cancers are cutaneous cancers, and 97% of them are non-melanocytic.
Key Clinical Symptoms and Signs:
- erythematous infiltrated papules and plaques, with a smooth, glossy surface, that slowly grow in size;
- location: mostly in the upper 2/3 of the face (80%), but also on the trunk and limbs;
- lesions generally are asymptomatic.
