Basal cell carcinoma is a skin cancer whose evolution is very favorable treatment.
Other skin cancers are squamous cell and malignant melanoma.
This is the most common cancer (nearly half of cases) in the United States and its incidence appears to increase.
It particularly affects people with fair skin (blond or red) and is correlated with exposure to sunlight and ultraviolet radiation.
Basal cell carcinoma may take many forms. The appearance pathognomonic (signing for sure diagnosis) is the pearl translucent.
A histological examination shows the tumor cells which are cells of the basal layer of the epidermis with abnormal proliferation and irregular.
The treatment is essentially a simple surgical excision with a safety margin around the visible edges of the lesion (often set at 5 mm). Microscopic examination of the surgical specimen must show that the tumor removal is complete to consider that the tumor is definitively treated, and removed the tumor will not grow. If excision is incomplete, the tumor will grow back from the few tumor cells still present in the skin.
They are only available in case of impossibility of surgically removed and their efficiency is lower with increased recurrence and cosmetic outcome less. Without treatment the tumor grows relatively quickly and can cover a large area of skin. The extension can be destructive, especially in the face. Another risk is the occurrence of new basal cell carcinoma, independent of the first. It is important to note that basal cell carcinomas do not metastasize [ref.
