Despite a dramatic increase in the use of mobile phones, there hasn’t been a matching rise in the incidence of brain cancer, reports a new study by scientists at the University of Auckland.
The research, which looked at trends in primary brain cancer incidence in New Zealand between 1995 and 2010 from New Zealand’s national cancer registry, calls into question claims that mobile phone radiation could be causing brain cancers.
“There has been no general increase [in brain cancer incidences],” says Mark Elwood, Professor in Cancer Epidemiology and co-author of the study.
“In fact, for the wide age range 10 to 69 years, there has been a decrease of about one percent per year.”
He says they have no idea what was behind the small decrease, but that this study along with similar studies done in other countries suggest that previous reports of large increases in risk in mobile phone users are likely to be incorrect.
“But a study of this type cannot exclude a small risk, or one limited to a certain subtype of cancers, or a risk only arising after more than about 15 years of phone use,” he says.
The research has been widely covered in national and Australian media. Examples include:
