Indoor tanning, even without burning, increases the risk of melanoma

Menée aux Etats-Unis auprès de 1 167 cas et 1 101 témoins, cette étude évalue l'association entre un bronzage artificiel et le risque de mélanome, selon la présence ou l'absence de brûlures antérieures liées à des rayonnements ultra-violets d'origine solaire ou artificielle

Résumé en anglais

People sometimes use indoor tanning in the belief that this will prevent burns when they tan outdoors. However, indoor tanning raises the risk of developing melanoma even if a person has never had burns from either indoor or outdoor tanning, according to a study published May 28 in the JNCI: Journal of the National Cancer Institute.
To test the hypothesis that indoor tanning without burns prevents sunburn and subsequent skin cancer, researchers at the Masonic Cancer Center, Department of Dermatology, and Division of Epidemiology and Community Health, University of Minnesota, Minneapolis used data from a case-control study on indoor tanning and the risk of melanoma. The researchers had detailed information on indoor tanning and sun exposure for the study participants and excluded those who experienced a burn while tanning indoors.
