The International Agency for Research on Cancer (IARC) has classified UV-emitting tanning devices as “carcinogenic to humans” (Group 1).
According to the IARC, analysis of over 20 studies shows that the risk of cutaneous melanoma is increased by 75% when the use of sunbeds starts before age 30. There is also evidence of an increased risk of ocular melanoma associated with the use of tanning devices. The IARC said that further studies on animals support these conclusions and demonstrate that ultraviolet radiation (UVA, UVB, and UVC) is carcinogenic to humans.
Prior to this statement, which was released a few days ago, sunbeds had been classified as "probably carcinogenic". Now they join cigarettes and asbestos.
