ACTINIC CHEILITIS AND ITS RELATIONSHIP WITH LIP CANCER

Abstract

Actinic cheilitis (AC) is a potentially malignant oral disorder of the lower lip vermilion, primarily caused by chronic and cumulative exposure to ultraviolet radiation. It predominantly affects men over 40 years old and rural workers exposed to the sun. The slow progression of the lesion and the absence of symptoms in the early stages favor late diagnosis, increasing the risk of transformation into squamous cell carcinoma, a neoplasm with a significant impact on public health. Given the high incidence and the scarcity of specific educational strategies aimed at raising awareness about photoprotection, this study is justified by the need to fill scientific gaps and promote early diagnosis. The objective of this study is to conduct a narrative literature review on actinic cheilitis, addressing its clinical, etiological, and histopathological aspects, as well as its relationship with lip cancer, emphasizing the relevance of early diagnosis and the adoption of preventive measures. The methodology was based on a reflective analysis of recent literature. It is concluded that the recognition of clinical features such as loss of the lip border, ulcerations, and leukosclerosis is essential for dental surgeons, and that continuous dental monitoring combined with preventive photoprotection behaviors are fundamental strategies to intercept neoplastic progression and reduce the morbidity and mortality associated with oral cancer.
