A 17 year biggest-ever study by Danish researchers reveals that people who used mobiles for 10 years or more was not associated with higher risks of cancer.
No link between cancer and mobile phone use: study finds
Previously, there was some study on this issue, yet they had no satisfied answer. The International Agency for Research on Cancer recently classified frequency electromagnetic fields, emitted by mobile phones, as possibly carcinogenic. However, the Danish study result shows clearly that cancer rates found in people without phones were the same as long-term users.
Cellphones send signals to nearby towers via radio waves, a form of energy similar to microwaves. But the radiation produced by cellphones cannot directly damage DNA and is different from stronger types of radiation like X-rays or ultraviolet light. At very high levels, radio frequency waves from cellphones can heat up body tissue, but that is not believed to damage human cells.
During study process, they studied about 360,000 Danish mobile users aged over 30 and born in Denmark after 1925 by gathering information on subscribers to mobile phones from the Danish phone network operators and from the Danish Cancer Register.
They analysed data of 10,729 central nervous system tumours between 1990 and 2007, says a report in bmj.com (the online site of the British Medical Journal).
According to Patrizia Frei of the Danish Cancer Society’s Institute of Cancer Epidemiology, lead author of the study published today in the journal BMJ, generally the findings were in line with most of the epidemiological research that has been conducted to date. They were also in line with in vitro and in vivo studies that show no carcinogenic effects on the cellular level.
So now you can have some useful information that: Cellphones do not emit the same kind of radiation as that used in some medical tests or found in other sources such as radon in soil. Ignore your fears of a link between mobile phone and cancer, the fact is cancer rates have not risen since cellphones were introduced.
You would be not more likely to get a tumor in the part of the brain closest to where phones are usually held against the head.
“This is encouraging news, but it doesn’t mean we’re at the end of the road,” said Hazel Nunn, head of Health Evidence and Information at Cancer Research U.K. However, further study should be continued. Studies with longer-term data were still needed and that there was little information on children’s exposure to cellphones.
Our experts suggested that people should not change their cellphone habits based on the current evidence, except perhaps for limiting their kids’ use of the devices.
And above all, this study would make us feel freely to use our mobile phone without afraid of increasing cancer.
