Melanoma rates are falling among young people, study finds
Sunburn used to be an inescapable part of childhood. Sunbathing outdoors and in tanning parlors used to be common. All that appears to be changing.
If you’ve wondered whether crusades promoting sun protection are making any difference, consider Rostraver Middle School, 25 miles southeast of Pittsburgh.
In hopes of winning a $5,000 grant offered by the Pennsylvania Academy of Dermatology and Dermatologic Surgery (PAD), pupils submitted essays about why sun safety matters. Sixth grader Maclaine Povlish’s winning entry earned her school a playground “shade structure” so kids could get away from damaging UV rays.
“Even though most of us would agree that the sun has many benefits, including helping the body produce vitamin D,” Povlish wrote, “it is just as important to understand the risks.”
Rostraver is anecdotal evidence of a trend tracked by Seattle researchers: a nine-year-long decline in melanoma rates among adolescents and young adults.
To be sure, the deadly skin cancer is still far more common in older people. Fewer than one in 100,000 adolescents were diagnosed in 2015, compared with 63 per 100,000 men ages 40 and over, according to the study, published this week in JAMA Dermatology.
Still, through 2005, melanoma incidence “was rapidly increasing in all age groups, including pediatric, adolescent, and young adults,” the authors wrote.
That changed between 2006 and 2015. The total number of melanoma cases in a national cancer registry fell by almost a quarter among adolescents (ages 10 to 19) and young adults (ages 20 to 29), from 2,903 to 2,224. The decline occurred even as the total population of adolescents and young adults was growing, said lead author Kelly G. Paulson, an oncologist at Swedish Cancer Institute in Seattle.
Meanwhile, melanoma cases and incidence continued to increase among adults 40 and over.
Jennifer M. Gardner, a dermatologist at the University of Washington School of Medicine who co-led the study, said the trend reflects generational changes that she sees in her practice.
“If you were to ask my parents how often my sister and I got sunburns, they would ask if you mean per year,” said Gardner, who is 40. “But when I ask parents how many sunburns their children have gotten, they just look at me and say, ‘None!’”
Her co-leader, Fred Hutchinson Cancer Research Center epidemiologist Margaret Madeleine, said, “There seems to be a breakthrough happening that might really reverse the trend of increasing melanoma incidence.”
Public health efforts promoting sun safety can work, as Australia’s “Slip! Slop! Slap!” campaign proved. Starting in 1981, a singing, dancing cartoon character named Sid Seagull exhorted people Down Under to slip on long sleeves, slop on sunscreen, and slap on a hat. Around 1998, melanoma rates began falling, particularly among younger adults.
While the United States hasn’t had anything as iconic as Sid Seagull, experts point to legal, economic, and cultural shifts.
For example, the indoor tanning industry has been decimated by research spotlighting its dangers and laws regulating salons. Forty-four states, including Pennsylvania and New Jersey, restrict minors’ access to indoor tanning. A federal “tanning tax” takes a chunk of revenue. And the Federal Trade Commission has cracked down on false claims that indoor tanning is healthful.
Pennsylvania last year became the 17th state to pass a law allowing schoolkids to carry and apply sunscreen as they wish, without a doctor’s note or going to the school nurse.
“It’s a commonsense thing,” said Erie dermatologist Scott Lim, president of PAD, which annually offers free skin cancer screening at the state Capitol.
The perception of sun-darkened skin is also evolving. A tan is still considered attractive — judging by the booming spray-tanning industry — but so is peaches-and-cream, Nicole Kidman-esque skin.
“A little bronzy glow is always desirable, but not that 'I laid out and baked’ look where you have dramatic tan lines,” declared a 2011 Glamour magazine article.
Jennifer Redmond, executive director of the state dermatology academy, said her children, ages 20, 17, and 11, have never sunbathed.
“They’ll do the spray tan,” she said. “But they carry sunscreen in their bags.”
The safety of some sunscreen ingredients remains a matter of debate and study, but that’s why Gardner, in Seattle, urges multiple protective measures.
“Sunscreen is one way to protect your skin,” she said. “But I also recommend clothing, hats, sunglasses, and shade.”
