The Effects Of Radiation In The Cause Of Cancer

Cancer is, unfortunately, spreading in the modern
society. Nearly all cancer forms are increasing when it comes to incidence, i.e. new cases/year
(cf. Hallberg & Johansson 2002a). It could recently be read in the
BBC
News that skin cancer is rising in young adults, and Sara Hiom, head of the health information at
Cancer Research UK said, when interviewed, that "Non-melanoma cancers are rising at an alarming
rate".
More and more research efforts goes into understanding the
molecular mechanisms behind these various progressive cancer forms, and much more money is spent on
finding new drugs to treat patients. However, oddly enough, very little is spent on
understanding the actual causes for cancer. Among such possible causative agents, more
and more focus is nowadays put on modern gadgets, such as mobile telephones and computers, and their
chemical and physical emissions, including flame retardants and electromagnetic non-ionising
radiation. |

 Non-melanoma
cancers are rising at an alarming rate
|
Childhood leukemia was
early connected to power-frequent magnetic fields already in the pioneering work by Wertheimer and
Leeper (1979), |
|
More recently Scandinavian scientists have identified an increased
risk for acoustic neuroma (i.e., a benign tumor of the eighth cranial nerve) in cell phone users,
as well as a slightly increased risk of malignant brain tumors such as astrocytoma and meningioma
on the same side of the brain as the cell phone was habitually held (Hardell et al. 1999, 2004,
2005; Lonn et al. 2004).
In addition, a clear association between adult cancers and
FM radio broadcasting radiation has been noticed, both in time and location (Hallberg &
Johansson 2002b, 2004, 2005a). Initial studies on facial nevi indicates that nowadays also young
children can have a substantial amount of these. If it can be shown that radiofrequent radiation
is not correlated with child cancers the current focus on low-frequency electromagnetic fields can
continue. If there is also a radiofrequent and/or microwave correlation then this must be
considered in future research as well as in today's preventive work.
Most recently, Dr. Djemal Beniashvili and other scientists at
the Edith Wolfson Medical Center in Holon, Israel, have demonstrated a possible link between exposure
to power-frequent electromagnetic fields and breast cancer in elderly women (Beniashvili et al.
2005). They compared the breast cancer rates in elderly women from an earlier period (1978-1990)
to a more recent period (1991-2003), which has been characterized by a much more extensive use of
personal computers (more than 3 hours a day), mobile telephones, TV sets, and other household electrical
appliances. They used available medical records extending over a period of 26 years, involving
the analysis of more than 200,000 samples. |

Among the elderly women who
developed breast cancer in the first time frame, 20 percent were regularly exposed to power-frequent
fields. But in the more modern period 51 percent were so exposed, mainly through the use of personal
computers. The authors concluded: "There was a statistically significant influence of
electromagnetic fields on the formation of all observed epithelial mammary tumours in the second
group." This represented a more than two-fold increase, which was considered highly significant (cf.
Beniashvili et al. 2005). |
Most
recently a possible link has been demonstrated between exposure to power-frequent electromagnetic fields and
breast cancer in elderly women |
|
Of course, many other environmental factors have changed during the
period 1978-1990, but increased environmental exposure to power-frequent fields is among the more conspicuous
changes to have taken place. Naturally, there are many aspects of this question that remain to be
clarified, and, from a scientific point of view, it is far from conclusively settled.
During the second half of the 20th century an increasing rate of lung
cancer was noticed in Sweden. Since mid 1960 tobacco smoking has been associated with this cancer and
believed to be the main cause. Less noticed, though, is the fact that no connection between smoking and
lung cancer was noticed before 1955. Together with my co-worker Örjan Hallberg we have therefore
initiated a project with the intention to review facts that may shed new light on this sudden increase in
getting lung cancer after 1955 in Sweden.
A large number of scientific reports point at tobacco smoking as
being the main cause to the increasing rate of lung cancer in the world. These reports have mainly been
produced during the second half of the 20th century. The Swedish National Board of Health and Welfare (Sw.
"Socialstyrelsen") states that 80-90% of the lung cancer deaths are caused by smoking. The main
part of the victims are also smokers. About 10% of the lung cancer deaths have been non-smokers.
This has led to the suspicion that also passive smoking can cause lung cancer. Other environmental factors
such as radon and asbestos are believed to cause a number of lung cancer deaths per year, and especially if
combined with smoking.
As pointed out above, Hallberg and Johansson have earlier reported
about a strong association between body-resonant non-ionising radiation (FM-radio, 100 MHz) and the existence
of malignant melanoma of the skin (Hallberg & Johansson 2002b, 2004, 2005a). Since this
frequency range has a penetration depth of about 10 cm into the human body there is a suspicion that resonant
currents may affect the immune defense system also when it comes to beating cancer cells in the lungs.
Due to that it is well motivated to study in detail how the presence and rate of lung cancer have changed in
Sweden, in the U.K., and in other countries as this new environmental factor was added. |

We
have shown how the rate of lung cancer can accelerate in connection with a sudden exposure of a population to
such body-resonant
radiation |
In a yet unpublished report (Hallberg &
Johansson 2005b), we have shown how the rate of lung cancer can accelerate in connection with a sudden
exposure of a population to such body-resonant radiation.
From this work, it can be noticed that persons, who
have been smoking for many years, suddenly could get lung cancer relatively short after the introduction of the
FM-radio. This abrupt increase was not noticed in counties where the FM-radio still was not rolled out. |
|
It is also noticeable that deaths due to asbestosis have not
been known until after the 1960's despite the fact that asbestos has been used as a building material since the
end of the 19th century. In our work it is also shown how weak the connection is between lung cancer and
cigarette consumption in a number of countries. But if the lung cancer mortality is normalized to the
melanoma of skin mortality in the same countries, all of a sudden a very strong correlation appears. This
indicates that there is a common factor behind the fast increasing mortality of skin and lung cancer that
we have noticed e.g. in Sweden.
An automated computer analysis of the age-specific incidence of lung
cancer among men in Sweden points at year 1955 as the starting year for a sudden environmental change in Sweden
and that this disturbance mainly affects men over 60 years of age. This method of analysis has
successfully been applied to study the development of melanoma of skin in Sweden, Norway, Denmark, Finland, and
the USA.
Authorities responsible for the health of the general population
should have a big interest in causative factors behind such major cancer types. Doctors and specialists
should know more about the real causes behind lung cancer. Epidemiologists in general might get inspired
to test new methods and to look at population health problems from a new perspective. Only the future,
however, will know the answer to these medical hypotheses.
