Latest Cell Phones and Cancer
2015 - Cell phones and cancer risk has been controversially debated for over decades.
But according to a recent study by some
researchers of the University of Bordeaux, in France, there is an increased risk of
cell phones and brain cancer
for heavy users.
Among potential malignant tumors users
may develop include glioma, a type of brain cancer particularly aggressive. The risk to have glial tumor
can be doubled among intensive users of mobile phones. This study confirms suspicious of the
devastating impact of mobile phones on human health.
electromagnetic fields in humans remains controversial. To shed more light, numerous studies
are unceasingly conducted
in different countries. This control study was conducted by Dr. Gaëlle Coureau and his colleagues at
University (French: Université Bordeaux Segalen), and Published for the
first time on 9 May
2014 in the journal
Occupational & Environmental Medicine. The results show that the intensive use of a cell phone is more
often found among patients that had brain cancer, glioma, or a less significant brain tumor called
meningioma; it is the most common
type of brain tumor but tends to be less aggressive than glioma.
The objective of the study, called "Cerenat",
was to analyze the connection between the
use of cell phones and brain cancer risk, mainly the development of glioma and meningioma in adults; although
there also studies on cell phones and breast cancer (and others), no conclusive finds have been released yet.
During the research, the researchers distinguish
these two types of tumors. Glioma is generally more dreadful, and it develops in the brain, often quite quickly.
Conversely, meningioma is generally less aggressive and it is, in principle, easier
to be surgically removed, given it arises
from the lining of the
The study includes benign or malignant
brain tumors that occurred between June 2004 and May 2006 in people over 15 years.
The Bordeaux researchers analyzed the
profile of patients who constantly used mobile phones in four French departments (counties): Gironde,
Calvados, Manche and Hérault. They then compared these profiles with
the residents of these departments (the same age, same sex) who also using mobile phones but have not had a
brain tumor. It was found a significant probability
that those with brain cancer had increased their risk of the disease due to their past habit of mobile phone
use compared to those who did not have cancer.
"It's a very solid
methodological study," said Prof. Gérard Lasfargues, Scientific Assistant Director General of ANSES; “it confirms what
was said the International
Agency for Research on Cancer (IARC) and ANSES (Spanish: Administración Nacional de la Seguridad Social; English: National Social Security
How to Reduce Cell Phone
glioma and meningioma are rare.
According to the
Cancer Brain Tumor Registry of the United
States (CBTRUS), primary brain tumors (glioma, meningioma, and all others) represent only 2% of all cancers.
In fact, for people who were born before 1950, the
risk of suffering from these cancers before age 75 is about
0.66% for men and 0.43% for women. But regardless of low risk, each
individual needs to reduce his risk, as much as he can.
The first and most effective step to take is to reduce regular or constant cell phone
exposure, particularly in heavy users and children. Use mobile phones only when it is necessary. People are
also recommended to use a headset (wired), or keep the device away from their head when the wave emissions
are highest: especially in seconds after dialing, and whenever there is one or two bars. Also to reduce your
cell phone and cancer risk, avoid using cell phones in areas where reception is poor: underground parking,
elevators, enclosed places, and others.
Before purchasing, buyers
need to focus on phones with SAR (specific absorption rate) as small as possible. For instance, some mobile
phones have a SAR well below 1 W / kg".
The FCC limit for public exposure from
cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg).
