But when it comes to skin cancer, the researchers say their findings support previous reports that both environment and genes affect skin cancer risk.

　　但在皮肤癌的问题上，研究人员称他们的发现与之前的研究一样，认为环境和基因对患皮肤癌风险均有影响。

　　Baron's team examined facial skin of 130 twins, 18 to 77 years old, who lived mostly in the northern Midwest and Eastern regions of the U.S. who were attending the Twins Days Festival in Ohio in August 2002.

　　巴伦的研究小组对130个年龄从18岁到77岁的双胞胎的面部皮肤进行了研究。这些双胞胎大部分居住在美国中西部偏北地区和东部地区，他们于2002年8月参加了在俄亥俄州举行的“双胞胎节”。

　　At this time, each of the twins also separately reported how their skin burned or tanned without sunscreen, their weight, and their history of skin cancer, smoking, and alcohol drinking.

　　在这项研究中，每对双胞胎也分别报告了他们的皮肤在没有涂防晒霜的情况下晒伤或晒黑的情况、他们的体重、患皮肤癌、吸烟以及喝酒的历史。
