WEDNESDAY, April 3 (HealthDay News) -- Melanoma, the most deadly form of skin cancer, doesn't usually occur in kids, but a new study shows that it's happening more often.
While melanoma in children is still extremely rare, the rate increased by about 2 percent per year from 1973 to 2009 among U.S children from newborns to age 19. Melanoma accounts for up to 3 percent of all pediatric cancers, according to the Skin Cancer Foundation.
According to the study, 1,317 children were diagnosed with melanoma during the study time frame. Of these, 1,230 children were white. Because the number of melanoma cases among other racial and ethnic groups was so small, researchers focused the analysis on white children.
The biggest jump in melanoma rates was seen among adolescents aged 15 to 19, especially girls, the study showed.
The new findings were published in the May print issue of Pediatrics.
Recent studies have also shown that melanoma is on the rise among adults as well. Exactly what is driving these trends is not fully understood, but increased exposure to ultraviolet radiation from both the sun and tanning booths as well as greater awareness of melanoma may be responsible, according to study authors led by Jeannette Wong of the U.S. National Cancer Institute.
The researchers used a database to capture trends in childhood melanoma, but they did not have any information on participants' tanning habits or sun exposure history.
Boys were more likely to develop melanomas on their face and trunks, while girls were more likely to have melanoma on their lower legs and hips, the investigators found. Other risks for melanoma among children and adults include fair skin, light-colored hair and eyes, moles, family history of melanoma and a history of sunburns.
Dr. Amy Forman Taub, a dermatologist in Lincolnshire, Ill., said that tanning behaviors have a lot to do with the increasing rates of melanoma in children and adults. "It's the tanning booths and the fact that we go away on vacation where we are exposed to a lot of intense sun," she said.
