Recent study finds no link between cell-phones & brain cancer

Earlier, it was thought that cell-phones are the major cause of brain cancer, but the study conducted on nearly 3,58,403 Danish cell phone subscribers from past 17 years does not support the theory. Scientists, after studying the subscribers, found that the subscribers above the age of 13 have equal chances of growing cancer as the non-subscribers.
Patrizia Frei of the Danish Cancer Society's Institute of Cancer Epidemiology and also the lead author of the study said, “In general, our findings are in line with most of the epidemiological research that has been conducted to date. They are also in line with in vitro and in vivo studies that show no carcinogenic effects on the cellular level.”
Everyone does not have similar views like Frie as some experts said that further research is required on this topic. Not only experts but, Frie herself believes that further study is required on the relationship of brain cancer and cell-phone usage.
Anders Ahlbom and Maria Feychting of the Karolinska Institute of Environmental Medicine in Stockholm, Sweden, wrote in a BMJ editorial, “Frei and colleague’s results may seem reassuring, but they must be put into the context of the 15 or so previous studies on mobile telephones and cancer. Although most of these studies were also negative, there are a few exceptions.”
Studies in Brain cancer & cell-phone relationship
Before this study, different study on Brain cancer & cell-phone relationship have been done and some say that there is a relation while some have contradictory opinion. Five months before this study a World Health Organization's panel of expert considered cell-phone as a probable cause of cancer.
A study in 2010 stated that they have found a significant increase in risk of a brain cancer known as Glioma in the cell phone users. Timothy Jorgensen, associate professor at Georgetown Lombardi Comprehensive Cancer Center said, “Most of data that shows an association between cell phones and brain cancer is very weak.”
Limitation with the studies
According to the experts, there are certain limitations in reaching to the conclusion in this study. Experts say that holding a cell phone subscription did not mean that the subscriber uses it also. In June, ABC news came to know that about 27 physicians out of 97 use hand free devices to minimize brain cancer risk.
