The protocol for the Interphone epidemiological study has been released by the International Agency for Research on Cancer (IARC) in Lyon, France. IARC is coordinating researchers in 13 countries in an investigation of the possible link between the use of mobile phones and the development of brain and salivary gland tumors. Some results have been made public, but not the overall findings, which could come any time now. (See also our commentary on some of the already published Interphone papers.)
