Holman, who was diagnosed with melanoma after noticing a changing mole on her stomach, attributes her diagnosis to her use of heavy indoor tanning in college.
“We know that even a single indoor tanning exposure can exponentially increase the risk of melanoma, and that women under 30 are six times more likely to develop early onset melanoma if they are indoor tanning users,” Holman said.
The reason? According to Holman, indoor tanning typically involves concentrated UVA radiation, which specifically increases the risk of melanoma.
“We typically think of UVB as the rays that cause sunburns, but UVA penetrates more deeply and increases that risk,” she said. “Skin cancer incidence is higher than that of any other human malignancy, and yet one of its root causes (ultraviolet radiation) is perhaps better understood than any other human carcinogen.”
