[Lip carcinoma. A review].

Lip cancer develops in the vermilion border of the lip. The great majority of these malignancies are squamous cell carcinomas. Lip cancer predominantly affects the lower lip and particularly occurs in males. The main risk factors involved are cumulative lifetime exposure to sunlight and the use of tobacco. It usually presents at an early stage. In the Netherlands (16 million inhabitants), approximately 190 new cases are registered annually. Since lip cancers in most instances are easily recognized, they may be diagnosed at an early stage. Lip cancer is best cured when it is diagnosed early. Dental examination should routinely include clinical examination of the lips and, on indication, palpation. This article reviews the clinical presentation, diagnosis and management of lip cancer.
