12.Tanning parlors take heat 人工日照美容院吸收热量
People who seek a glamorous tan through sun lamps may double their risk of developing common types of skin cancer, according to a new study that found the risk was highest for those who start at a young age.
The study, appearing in the latest issue of Journal of the U.S.National Cancer Institute,concluded that people who use tanning devices were 1.5 to 2.5 times more 1ikely to have common kinds of skin cancer than were people who did not use the devices.
The study confirmed what doctors have long suspectedthat sun lamp use increases the risk of basal cell and squamous cell skin cancers,said Margaret R.Karagas,first author of the study.
Either going to the tanning parlor,or getting an infrequent sunburn can seriously damage the skin,said Dr.James Spencer,vice chairman of the department of dermatology at Mount Hospital,but the small.day.to.day exposure is worse for the skin in the long run.
Joseph A.Levy,vice president of the International Smart Tan Network,however,said occasional sunburn is a risk factor in all forms of skin cancer and intermittent sunburn is what the tanning industry is trying to stop.
In the study, Karagas and her colleagues interviewed 603 basal cell skin cancer patients and 293 with squamous cell skin cancer.They talked to 540 control subjects, who did not have either type of skin cancer.
About l million Americans are diagnosed annually with skin cancer.Among those skin cancer patients,about 80 percent are with basal cell skin cancer,16 percent,with squamous cell skin cancer and 4 percent, with melanoma.the most serious form of skin cancers.Back to the interviewed patients,190 reported that they had used tanning devices at some time.In the control groups,only 75 had used such devices.Karagas said a statistical analysis shows that those who used tanning equipment were 2.5 times more likely to get squamous cell skin cancer than those who had not used the devices.For basal cell cancer.the risk was 1.5 times greater.
The risk was highest for those who first used the tanning devices before the age of 20,said Karagas.For this group,the squamous cell cancer risk was 3.6 times greater than that of the controls while the basal cell cancer risk was 1.3 times greater.
