Handheld Cellular Telephone Use and Risk of Brain Cancer

Abstract

Our data suggest that use of handheld cellular telephones is not associated with risk of brain cancer, but further studies are needed to account for longer induction periods, especially for slow-growing tumors with neuronal features.

Mobile phone use and risk of glioma in 5 North European countries

“…Excluding the subjects who had used mobile phone on both sides of the head from the analyses did not The numbers do not match exactly to the total numbers of cases and controls since there were strata without cases and strata without controls in the data. We report here the numbers of cases and controls that are actually included in the analyses and for whom the values of the explored exposure variables were known.- 2 The reference category consists of subjects with never/nonregular use of any type of phone.-3 Lower limit 1.5 years since phone use was defined as regular when the phone was used at least 6 months during the period at least 1-year before the reference date.- 4 Estimates adjusted for use of hands-free devices. For cumulative number of calls the data are divided, based on the distribution in controls, into <2,920, 2,920-8,583 and >8,583 for analogue phones, and <1,829, 1,829-6,019 and >6,019 for digital phones.…”

“…The studies published on the issue have covered a relatively small number of study subjects with long-term exposure, and so far the epidemiological evidence does not suggest any clear increase of intracranial tumors related to mobile phone use, although some positive findings have been reported. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] We conducted a collaborative population-based case-control study on the association of mobile phone use with intracranial tumors in 5 Northern European countries, using a shared protocol of the INTERPHONE study coordinated by the International Agency for Research on Cancer. 20 We report here the results concerning glioma, based on the combined data from Denmark, Finland, Norway, Sweden and Southeast England, where mobile phones have been widely used for at least a decade.…”

Telefones celulares: influência nos sistemas auditivo e vestibular

“…5,16 There is no evidence supporting the influence of mobile phone use on the occurrence of benign or malignant CNS tumors, especially those located in the temporal lobe. 17,18,24 Results of studies on mobile phone handset radiation and the risk of developing acoustic neuroma have been contradictory (Table 1). Some authors have found no increased probability of tumor development in mobile phone users, 18,19,21,24 while other have stated that the use of mobile phones -particularly analog handsets -for 10 years or more is a risk factor for developing tumors.…”

Ernst Wynder: A remembrance

“…While not shying away from studies of "hot" topics such as cellular telephones and brain cancer, 34 Wynder firmly believed in a saying he attributed to E. V. Cowdry, Chair of Pathology at Washington University, author of one of the earliest textbooks on cancer etiology, 35 and one of Wynder's mentors: common diseases have common causes. That belief kept him focused on tobacco and nutrition and their relation to the most common cancers: lung, colon, breast, and prostate.…”
