Is There Truly No Benefit with Sunscreen Use and Basal Cell Carcinoma? A Critical Review of the Literature and the Application of New Sunscreen Labeling Rules to Real-World Sunscreen Practices

الملخص EN

Basal cell carcinoma (BCC) is the most common human malignancy.

Both epidemiological and direct evidence have established ultraviolet (UV) exposure from the sun as the most important risk factor for BCC development.

There has only been one randomized and controlled study to examine sunscreen's role in the prevention of BCC, and no significant protective benefit was found.

This study did not address four important concepts: sunscreen abuse, sunscreen misuse, sunscreen formulation, and cumulative UV exposure.

Thus, the results of this study are difficult to interpret and extrapolate with real-world sunscreen practices.
