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.

研究表明,没有证据显示防晒霜通常是减少皮肤癌的危险,实际上增加患病危险.
来自爱渥华大学的研究者在18项早期对于防晒霜和黑素瘤的联系研究基础上,建立了他们的研究成果.他们表示,关于防晒霜的使用和更恶化的黑素瘤的相关报告纯在问题.
大部分的健康专家相信,为了保护皮肤不受太阳有害的影响,防晒霜能够帮助阻止皮肤癌,而皮肤癌正是在美国发病率高于其他癌症的疾病.
但问题是被重新提出,防晒霜是否有相反的作用,也许能够保护人们更长时间日晒而不被晒伤.
研究者指出,早期的研究,都未能考虑哪些处于换皮肤癌高风险的人群,比如那些皮肤很白和有雀斑的人,他们更愿意用防晒霜.结果是,这将引起防晒霜使用者更容易患皮肤癌.
新的研究表明,基本上依靠于那些志愿者对于以前使用防晒霜的回忆,并不能够证明这些产品是否起到适用的效果.
