A study of 30 years’ worth of data has concluded that no link exists between mobile phones and brain cancers.
The study, out of Australia, pores over the prevalence of brain tumors since 1987, reports the Daily Mail.
During this 29-year period — a time when mobile phone usage has increased dramatically — there was no corresponding increase in cancerous brain tumors.
The study noted that 9 percent of Australia’s population had cell phones in 1993. Today, the phones are ubiquitous, with 90 percent of all residents owning one.
During the same period, rates of brain cancer remained basically stagnant. Brain cancer rates did go up slightly among men aged 20 to 84. Among women in this age range, rates were unchanged.
Rates of brain cancer along elderly people in Australia have seen a “significant” increase, according to the study. However, the significant escalation in brain cancer rates among Australia’s old people began in 1987 — five years before pretty much anyone in Australia was buying mobile phones.
The study investigated the incidence of brain cancer among 19,858 men and 14,222 women who have been diagnosed with brain cancer from 1982 to 2012. It also examined overall mobile phone usage from 1987 to 2012.
One reason for the slight increase in brain cancer among men could be an increase in the number of diagnoses — and not the actual number of occurrences, the study notes.
“Our study follows those published about the United States, England, the Nordic countries and New Zealand where confirmation of the ‘mobile phones cause brain cancer’ hypothesis was also not found,” notes the scientist who conducted the research, University of Sydney professor Simon Chapman.
Chapman wrote in detail about his findings in The Conversation, an academic website.
