Tanning parlors take heat 人工日照美容院吸收熱量

　　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 suspected—that 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．

　　譯文：

　　一項(xiàng)新的研究結(jié)果表明，欲通過(guò)人工日照獲得誘人的黑色皮膚的人們使自己患皮膚癌的風(fēng)險(xiǎn)倍增。研究還發(fā)現(xiàn)，那些從年輕時(shí)就進(jìn)行人工日照的人的風(fēng)險(xiǎn)系數(shù)是最高的。

　　這項(xiàng)發(fā)表在最新一期的美國(guó)國(guó)家癌癥研究會(huì)雜志的研究結(jié)果認(rèn)為，使用了人工日照措施的人們比那些未使用的人們患皮膚癌的可能性要高出1.5至2.5倍。

　　該項(xiàng)研究成果的第一作者M(jìn)argaret．R．Karagas說(shuō)，該項(xiàng)研究證實(shí)了醫(yī)生長(zhǎng)期的懷疑，使用人工日照增加了患基細(xì)胞和冠狀細(xì)胞皮膚癌的風(fēng)險(xiǎn)。

　　Mount醫(yī)院皮膚病學(xué)部副主任James Spencer 博士說(shuō)，無(wú)論是去人工日照美容院還是偶爾的皮膚曬傷都會(huì)對(duì)皮膚造成嚴(yán)重的傷害，但從長(zhǎng)遠(yuǎn)來(lái)說(shuō)，每天的少量接觸對(duì)皮膚更為有害。

　　然而，國(guó)際人工日照網(wǎng)的副總裁Joseph A．Levy卻說(shuō)，偶爾的曬傷是導(dǎo)致各種皮膚癌的危險(xiǎn)因素，是人工日照行業(yè)所盡力制止的。

　　在研究過(guò)程中，Karagas和同事們采訪了603名基細(xì)胞皮膚癌患者和293名冠狀細(xì)胞皮膚癌患者。他們還與未患皮膚癌的540名對(duì)照組實(shí)驗(yàn)對(duì)象進(jìn)行了交談。

　　每年大約有1百萬(wàn)美國(guó)人被診斷為患有皮膚癌。在這些皮膚癌患者當(dāng)中，約80%為基細(xì)胞皮膚癌患者，16%為冠狀細(xì)胞皮膚癌患者，4%為黑素瘤皮膚癌患者，這是最嚴(yán)重的一種皮膚癌。我們?cè)倏幢徊稍L的患者當(dāng)中，其中190人說(shuō)他們?cè)��?jīng)用過(guò)人工日照措施，而在對(duì)照組實(shí)驗(yàn)對(duì)象中，只有75人曾經(jīng)進(jìn)行過(guò)人工日照。Karagas說(shuō)，統(tǒng)計(jì)分析說(shuō)明，使用過(guò)人工日照設(shè)施的人比未曾使用過(guò)的人患冠狀細(xì)胞皮膚癌的幾率要高2.5倍，患基細(xì)胞皮膚癌的風(fēng)險(xiǎn)要高1.5倍。

　　Karagas說(shuō)，20歲之前就使用人工日照設(shè)施的人的患病風(fēng)險(xiǎn)是最高的。這組人群當(dāng)中患冠狀細(xì)胞皮膚癌的風(fēng)險(xiǎn)比對(duì)照組高出3.6倍，而患基細(xì)胞皮膚癌的風(fēng)險(xiǎn)則要高出1.3倍。
