Cell phones：Is there a cancer link?
Worrying about the possibility that phones，power lines and Wi-Fi could be responsible for a range of illnesses，from rashes （疹子）to brain tumors ．
Some say there is evidence to support the growing anxieties．David Carpenter，a professor of environmental health sciences at the university at Albany，in New York，thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia (a kind of blood disease)．Also there’s a greater than 90 percent chance that cell phones can cause brain tumors．“It’s clear now that there’s a real risk，”said Carpenter． But others believe these worries caused by some experts’ warnings are not justified (验*)．Dr Martha Linet，head of radiation epidemiology(流行病学)at the US National Cancer Institute，has looked at the same research as Carpenter but has reached a different conclusion．“I don’t support warning labels for cell phones，”said Linet．“We don’t have the evidence that there’s much danger．” Studies so far suggest a weak connection between EMFs (电磁场)and illness—so weak that it might not exist at all．A multinational investigation of cell phones and brain cancer，in 13 countries outside the US，has been under way for several years．It’ s funded（provide money） in part by the European Union，in part by a cell phone industry group．The final report should come out later this year，but data so far don’t suggest a strong link between cell phone use and cancer risk． 25．From the passage we can learn that some people are worried because________.
