Cell Phone Use, Acoustic Neuroma and Cancer of the

Pituitary Gland

Cell phone use was associated with increased risk of two types of brain tumors in a new study of 790,000 women.




PRLog (Press Release) – May 10, 2013 – BERKELEY, Calif. — Cell phone use was associated with increased risk of acoustic neuroma and cancer of the pituitary gland in a prospective study of more than 790,000 women in the United Kingdom. (1)

Acoustic neuroma is a rare, non-malignant tumor that develops on the main nerve leading from the inner ear to the brain. The pituitary gland is an organ that produces hormones which regulate important functions of the body and is located in the middle of the base of the brain.

Women who used cell phones for ten or more years were two-and- a-half times more likely to develop an acoustic neuroma. Their risk of acoustic neuroma increased with the number of years they used cell phones.

The results for acoustic neuroma re-affirm one of the two major conclusions by the World Health Organization (WHO) in its recent monograph about radiofrequency electromagnetic fields and form the basis for classification of cell phone radiation as “possibly carcinogenic” to humans:

“Positive associations have been observed between exposure to radiofrequency radiation from wireless phones and glioma, and acoustic neuroma.” (p. 421) (2)

The risk of cancer of the pituitary gland more was more than twice as high among women who used a cell phone for less than five years as compared to never users. Although the risk was elevated for women who used a cell phone for ten or more years (about 60% greater than never users), this effect was not significant. Since this may be the first study to find an association between cell phone use and pituitary cancer, further research on this cancer is necessary.

The women reported their cell phone use in 2005 to 2009 and again in 2009 and were followed through 2011 to see whether they developed tumors. The analyses controlled for other factors associated with tumor risk.

The study had numerous weaknesses which may explain why the research failed to replicate the increased risk of glioma associated with cell phone use of ten or more years found in several previous studies. Although this was a prospective study, the assessment of cell phone use was poor. Cell phone use was measured only at two time points and in a crude manner. The authors considered anyone who used a cell phone at least a minute per week to be a cell phone user. Although the authors measured the amount of cell phone use per week at follow-up, they did not report these results.The study did not assess cordless phone use or other microwave radiation exposures that are similar to cell phone emissions. If the never-cell phone users were cordless phone users, the effect of cell phone use on brain tumor risk would have been underestimated.

Since brain tumors can take decades to develop, the study underestimates the long term risk due to cell phone use as the average follow-up period for cell phone users was only seven years. Few women (about 8%) in this study used cell phones for ten or more years. Moreover, the women in this study may have used their cell phones much less than women do today.

The study was published online in the International Journal of Epidemiology on May 8, 2013. The authors are affiliated with the University of Oxford and the World Health Organization’s International Agency for Research on Cancer.

If you still doubt that cell phone tumor
studies are free of political agendas, take
a look at a new paper from the U.K.

This is the fourth epidemiological study to show a
risk of developing an acoustic neuroma, a tumor of the
auditory nerve, following long-term use of a cell phone.

Yet, the authors neglect to highlight this key
finding in the conclusion section of their abstract,
focusing instead on the absence of an increase
in brain cancer.

The research team, which includes Valerie Beral of Oxford
University and Joachim Schüz of IARC, also touts
the study as prospective. We disagree. It is really no
better than previous retrospective studies.

The controversy continues, with no end in sight.
