Basal Cell Carcinoma

Basal cell carcinoma is the most common type of skin cancer. It originates in the basal cells of the deepest layer of the epidermis and usually grows slowly and locally.

Usual appearance: It may appear as a pearly or shiny bump, a reddish patch, or a small sore that does not quite heal, above all on the face, neck, and other areas exposed to the sun.

What to watch for: A lesion that bleeds easily, reopens, or changes shape deserves attention.

Professionals who take part: The dermatologist is key to recognizing and studying these lesions; in certain cases the oncologist and the radiation oncologist collaborate. If you discover a mark on the skin that does not go away, showing it in consultation allows it to be assessed in time.
