Artificial sun dangerous, too

WASHINGTON - Regularly baking to a golden tan under sun lamps can increase the risk of malignant melanoma, a sometimes fatal skin cancer, and the younger a woman starts the greater the risk, a study says.
In the study, appearing this week in the Journal of the National Cancer Institute, an international group of researchers analyzed data from the Women's Lifestyle and Health Cohort Study in Norway and Sweden. In 1991 and 1992, 106,379 women between the ages of 30 and 50 completed questionnaires about their exposure to sunlight and to artificial tanning. In 1999, researchers rechecked the women's cancer status.
They found 187 cases of malignant melanoma. They also found that women of any age or hair color who regularly visited tanning salons once or more per month increased their chance of developing melanoma by 55 percent.
The risk was highest for young adults. Women who used artificial tanning systems once or more per month when they were between the ages of 20 and 29 increased their risk of melanoma by about 150 percent.
About 50,000 cases of melanoma are diagnosed annually in the United States and about 7,500 people die of the disease each year.
