Study links tanning salons, cancer risk

WASHINGTON—Women who visit tanning salons more than
once a month are 55 per cent more likely to develop malignant
melanoma, according to an eight-year study of more than
100,000 Scandinavians.
The risk more than doubles for women in their 20s who
frequent tanning parlours, the study says.
The study, appearing this week in the Journal Of The
National Cancer Institute, analyzed the lifestyle and
melanoma risk for women between the ages of 30 and 50. They
found that sunburns and tanning-lamp use during the adolescent
and early adult years significantly increase susceptibility to
skin cancer.
Melanoma risk is highest among fair-skinned people in
Australia, New Zealand, Europe and North America. The rates of
skin cancer have tripled in Norway and Sweden since the 1950s,
the researchers found.
In the study, an international group of researchers
analyzed data from the Women's Lifestyle and Health Cohort
Study in Norway and Sweden. The study enrolled 106,379 women
in 1991 and 1992. They all completed extensive questionnaires
about their personal exposures to sunlight and to artificial
tanning.
In 1999, the researchers rechecked the women's health
using the national health registries in Norway and Sweden.
The researchers found 187 cases of melanoma diagnosed
among the study group during the eight-year followup period.
They found that women of any age or skin tone who
regularly visited tanning salons once or more per month had a
55 per cent increased chance of developing melanoma, but the
risk was highest for women in their 20s.
Compared to women who never used a solarium, women
between the ages of 20 and 29 who reported using artificial
tanning systems once or more per month increased the risk of
melanoma about 150 per cent.
"Our results provide stronger evidence than those of
other studies that solarium use is associated with an
increased risk of melanoma," the authors wrote in the study.
The study also found that the risk of melanoma from sun
exposure was about two times higher for blondes than for women
with brown or black hair.
For red-haired women, the risk was about four times
greater, the researchers said.
