A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increase the risk.
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.

一项新的研究发现,大家平时使用的所谓能降低患皮肤癌风险的防晒霜,它实际上增加了患上皮肤癌的风险.
这些科学家来自爱荷华大学,他们以前期18份研究防晒霜与黑素瘤关系的研究成果为基础.他们声称找到了那些研究的缺陷,那些研究之前曾发表过关于使用防晒霜与患皮肤癌的机率的报道.
大部分的健康专家都认为防晒霜通过保护皮肤免受有害的太阳辐射,能有效抑制皮肤癌.皮肤癌在美国的发生率是癌症病症中最高的.
但是关于防晒霜是否有副作用的问题已经被提出.因为使用防晒霜,使人们更长时间暴露在阳光下.
这些研究者说,早期的研究都未能考虑到最易患皮肤癌的人群——白肤金发者和雀斑患者他们更易于使用防晒霜.其结果则可能是防晒霜使用者更易患上癌症.
该研究也指出说,因为这些研究多是基于志愿者们对于防晒霜使用情况的回忆,它不能证明产品是否被正确使用.

一项新的研究发现,没有证据表明防晒、常用的降低皮肤癌的危险,实际上增加这种风险。

艾奥瓦大学的研究人员发现,并根据他们18岁的早期研究,看着之间的关联应用防晒霜,黑素瘤(黑素瘤)。他们说他们发现缺陷的研究中,有报道,应用防晒霜之间有关联的风险更高,黑素瘤。

一项新的研究发现,没有证据表明防晒、常用的降低皮肤癌的危险,实际上增加这种风险。

艾奥瓦大学的研究人员发现,并根据他们18岁的早期研究,看着之间的关联应用防晒霜,黑素瘤(黑素瘤)。他们说他们发现缺陷的研究中,有报道,应用防晒霜之间有关联的风险更高,黑素瘤。

大多数健康专家相信,保护皮肤不受太阳的不利影响,防晒霜有助于防止皮肤癌的发病率,增加(发生率)的速度比其他任何癌症在美国。

但问题已经筹集了防晒霜,是否有可能有相反的作用,或者通过允许人们继续暴露在太阳不燃烧。

研究者说在这个问题的一些早期的研究和不可思议的是,他们往往没有考虑到那些人最危险的皮肤癌——患有白皙的皮肤和雀斑(雀斑,例如——更倾向于使用遮光剂。作为一个结果,看来防晒用户得到癌症更多。

这个研究,它通常依赖志愿者回忆起他们的防晒剂使用,也不能证明我们究竟有多么好产品已经在说,这项新研究。
