University of Sydney in Australia observed the trend of brain cancer diagnosis Kangaroo State citizens within a period of 29 years between 1982 and 2012.
Data shows 19 858 men and 14,222 women aged 20-84 years who are diagnosed with brain cancer in a span of cancer is then compared with the trend analysis of cell phone use.
From here, as summarized KompasTekno of The Sydney Morning Herald, Tuesday (10/05/2016), found no association between increased cell phone use with brain cancer incidence rates.
"The incidence of brain cancer in the period 1982 and 2013 did not increase in any age group except 70-84 years of age," the researchers wrote in a report published in the journal Cancer Epidemiology, last week.
In fact, the rate of mobile phone usage in Australian society increased sharply by 9 percent of the total population in 1993 to 90 percent today.
Indeed, there was an increase in cases of brain cancer in the elderly, but this happened in 1982, five years before mobile phones came to Australia in 1987.
"(The increase in cases of brain cancer) most likely due to the increasingly sophisticated methods of diagnosis in Australia," said lead researcher from the University of Sydney, Simon Chapman.
Another study assumed that the tendency of cancer caused by new phones will peak after 40 years of pause (latency / lag).
If so, Chapman argued that the increase in cancer cases should be starting to look now. In contrast, the figure is even ramp.
Then, why not cell phone radiation cause cancer? Different from nuclear radiation ionizes nature (energy large enough to produce ionization), Chapman said that cell phone radiation does not damage the DNA strands within cells of the human body that can cause cancer.
"Mobile phones generate non-ionizing radiation that the effect of low-energy electrons only heats," said Chapman.
