Can cell phones promote brain tumors the INTERPHONE study?

Within the past few months, several papers reporting epidemiological studies of cell-phone use and brain tumors have appeared in scientific journals. Several other related manuscripts are likely to appear, in print, in the not too distant future. If one wonders about the timing, it is very simple: a multi-year, international research effort, the INTERPHONE Project, is approaching its final phase. This human health project is being conducted with 13 participating countries.
