Cancer Doc Tells Colleagues to Lay Off Cellphones
Posted by Scott Hensley
In a startling warning on cellphone safety, the head of a cancer research center in Pittsburgh told faculty and staff to curb their use of mobile phones because of a possible risk of cancer.
The alarm came from Ronald Herberman, director of the University of Pittsburgh Cancer Institute, the Associated Press reports.
His advice, contained in a memo to 3,000 faculty and staff, says kids should only use cellphones for emergencies and adults should keep the phones away from their heads by using speakerphones or a wireless headset.
It’s hard to know exactly what Herberman knows that the rest of us don’t. His warning is based on existing studies and also, in part, on “early unpublished data,” according to the AP. His stance is in conflict with the preponderance of scientific work that hasn’t demonstrated a link between talking on cellphones and cancer. Some studies have suggested cancer risks, however.
Of course, proving a negative–especially in the field of cancer causation–is notoriously difficult. The FDA’s standing advice to consumers says, “The available scientific evidence does not show that any health problems are associated with using wireless phones. There is no proof, however, that wireless phones are absolutely safe.” For more, check out the FDA’s Q&A on cellphones.
Herberman told the AP: “Really at the heart of my concern is that we shouldn’t wait for a definitive study to come out, but err on the side of being safe rather than sorry later.” Ironclad answers take too long, he said, and it’s time for people to take action — especially when it comes to kids’ health.
Cellphones emit low levels of radiowaves during conversations, and even lower levels in standby mode. Higher levels of these sorts of waves than are produced by cellphones can damage tissue by heating, the FDA explains. But exposure to low levels that don’t cause heating aren’t linked to any “known adverse health effects.”
Still, there is enough static in the studies to date that the National Cancer Institute says, “Although research has not consistently demonstrated a link between cellular telephone use and cancer, scientists still caution that more research needs to be done before conclusions can be drawn about the risk of cancer from cellular telephones.” 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领。 Cancer Doc Tells Colleagues to Lay Off Cellphones
肿瘤科医生建议同事少用手机
1. In a startling warning on cellphone safety, the head of a cancer research center in Pittsburgh told faculty and staff to curb their use of mobile phones because of a possible risk of cancer. The alarm came from Ronald Herberman, director of the University of Pittsburgh Cancer Institute, the Associated Press reports.
作为对于手机安全性的示警，美国匹兹堡大学癌症研究所的所长Ronald Herberman决定倡导该机构内的成员和员工竟可能少用手机，以避免带来致癌风险。
2. His advice, contained in a memo to 3,000 faculty and staff, says kids should only use cellphones for emergencies and adults should keep the phones away from their heads by using speakerphones or a wireless headset.
他建议儿童仅仅在紧急情况下使用手机，成人则尽可能使手机远离头部，多用座机或者无绳电话。这一建议已经被记录在针对研究所内3000员工的备忘录中。
3.It’s hard to know exactly what Herberman knows that the rest of us don’t. His warning is based on existing studies and also, in part, on “early unpublished data,” according to the AP. His stance is in conflict with the preponderance of scientific work that hasn’t demonstrated a link between talking on cellphones and cancer. Some studies have suggested cancer risks, however.
Herberman是否掌握了一些公众并不知晓的信息，目前还不得而知。他的警告是基于目前已有的一些研究，但美联社称，也有一些尚未发表的数据。目前绝大多数的实验都未能证明手机和肿瘤的发病有联系，当然也有少数实验认为手机会增加罹患肿瘤的风险，Herberman的观点，显然是和主流观点冲突的。
4.Of course, proving a negative–especially in the field of cancer causation–is notoriously difficult. The FDA’s standing advice to consumers says, “The available scientific evidence does not show that any health problems are associated with using wireless phones. There is no proof, however, that wireless phones are absolutely safe.” For more, check out the FDA’s Q&A on cellphones.
当然，证明某事物完全不会增加癌症的发病风险是很冒险的。FDA对于手机安全性的评价是：“目前尚无确凿的科学证据证明手机会导致健康问题，但也没有证据说明手机是绝对安全的。”更详细的内容可以参照FDA关于手机的问答指南。
