A high-profile international study of the impact of cell phones on childhood brain tumor risk is sending the signal that there is no “exposure-response relationship. However, some environmental health experts contend that significant safety concerns are hidden within the data.
CEFALO, a multi-center European project, is the first study to look specifically at the impact of self-reported mobile phone use on risk of childhood brain tumors.

Writers from the Environmental Health Trust challenge CEFALO's findings; a spokesman from the study team responds.
Hospital administrators are finally starting to reckon with the damaging effects their institutions can have on the environment. Janet Brown, HPC's resident medical environmentalist, reports from CleanMed, the nation's largest conference dedicated to health care and ecology.
