Lennart Hardell
Lennart Hardell, born 1944, is a Swedish oncologist and professor at Örebro University Hospital in Orebro, Sweden.〔(Lennart Hardell Bio )〕 He is known for his research into what he says are environmental cancer-causing agents, such as Agent Orange, and has said that cell phones increase the risk of brain tumors.
==Mobile phone use and cancer==
Hardell's research on cell phones and cancer has concluded that long-term mobile phone use is associated with an increased risk of acoustic neuroma and glioma. He has said that children should be banned from using cell phones except in emergencies, as he feels the risk of cancer is greater in people who begin using mobile phones before the age of 20.
His research was criticized in a 2002 review for methodological flaws. The review authors, John D. Boice Jr. and Joseph K. McLaughlin, wrote that Hardell's study, published in the ''European Journal of Cancer Prevention'', was "non-informative, either because the follow-up was too short and numbers of cancers too small, or because of serious methodological limitations." Another of Hardell's studies, in which he claimed that mobile phone users in rural areas were at a greater risk of developing brain tumors, was criticized by Adam Burgess in ''Spiked''. Burgess wrote that the study was "post hoc and therefore hypothesis-generating only," and said that the increased risk Hardell had claimed to have found in the study was "barely statistically significant."
