Broad-Spectrum Sunscreen Use and the Development of New Nevi in White Children

Abstract

Our data indicate that broad-spectrum sunscreens may attenuate the number of nevi in white children, especially if they have freckles. JAMA. 2000.

Epidemiologic Evidence for Different Roles of Ultraviolet A and B Radiation in Melanoma Mortality Rates

“…The UVA hypothesis accounts for the significantly higher prevalence of melanocytic nevi that was found in children whose parents regularly applied UVB sunscreens to them (43), although another study found a minimal reduction (44). It is consistent that the number of sunburns the child had experienced was not associated with nevus count (43).…”

Melanoma Epidemiology and Prevention

“…This same concern has been advanced in studies showing that population that used sunscreen had greater melanocytic nevi, an indicator of sun exposure [9,10,11,12,18,19,148], although a recent study from Canada found that sunscreen reduced nevi in a randomized prospective design [74]. The negative effects of sunscreen may be most evident when individuals choose to be outdoors in the sun rather than when their time in the sun is determined by factors out of their control such as work schedules.…”

Rhetorical gamesmanship in the nano debates over sunscreens and nanoparticles

“…There is an extensive literature that accords to sunscreens the capacity to reduce DNA damage (Gallagher 2005;Lee et al 2005;Mahroos et al 2002;Young et al 2000;Gallagher et al 2000a;Gallagher et al 2000b). Gallagher of the Cancer Control Research Program of the British Columbia Cancer Agency (2005) reported that ''a number of trials have provided good evidence that, when applied consistently, sunscreens can realistically play a role in reducing the risk of squamous cell carcinoma'' (244).…”
