The incidence of melanoma has been rapidly increasing in the United States. Since exposure to UV radiation from indoor tanning is preventable, reducing exposure is an important strategy for melanoma prevention.1 The article by Lazovich et al2 in this issue of JAMA Dermatology provides an in-depth analysis of a case-control study conducted in Minnesota examining the association between indoor tanning and melanoma. The authors2 found that indoor tanning was strongly associated with increased melanoma risk among women, especially among women younger than 30 years, for whom indoor tanning was associated with a 6-fold increase in the likelihood of developing melanoma. Nearly all women in the study (96.8%) diagnosed as having melanoma when younger than 30 years had engaged in indoor tanning, all initiating indoor tanning before age 25 years, and nearly all (90.5%) engaging in frequent indoor tanning (>10 times per year).
