On May 31, the New York Times ran a piece in what it calls “The Upshot” on the National Toxicology Program’s (NTP) cell phone animal study. The column is a regular feature in the Times that seeks to give readers context for stories in the news. This one was titled “Why It’s Not Time to Panic About Cell Phones and Cancer.” It was written by Aaron Carroll, a pediatrician at the Indiana University School of Medicine.
Carroll outlined reasons for his skepticism over the cancer results, calling the $25 million NTP study “imperfect.” This prompted a response from Ron Melnick, who led the study’s design team before he retired in 2009. In an eight-point rebuttal, Melnick corrected what he called “numerous and misleading statements.” The full text of his letter is reprinted below.
