Broad-spectrum sunscreen use and the development of new nevi in white children: a randomized controlled trial.Richard P. Gallagher; Jason K. Rivers; Tim K. Lee; Chris D. Bajdik; David I. McLean; Andrew J. ColdmanJAMA. 2000;283:2955-2960

The relationship between sunscreen use and the risk of melanoma is controversial. Previous case-control studies have shown rates of sunscreen use in patients with melanoma that were higher than, the same as, or lower than in those in controls.1 Because high nevi counts are a predictor of melanoma, the objective of this prospective, randomized controlled study was to determine whether the use of a "broad-spectrum" sunscreen with a sun protection factor of 30 attenuates the development of melanocytic nevi in white Canadian children.
