World Health Organization(WHO) Estimate That Mobile Phone is Carcinogenic


International experts, brought together by the World Health Organization (WHO), said that mobile phone use may be carcinogenic and argue for the use of headphones and sending text messages.
"The tests, which continue to accumulate, are strong enough to justify" the compilation of mobile phone use as "possibly carcinogenic to humans", estimated Jonathan Samet, chairman of the working group of experts assembled thirty eight days in Lyon (southeast).

These experts met under the aegis of the International Agency for Research on Cancer (ICRC), an agency of WHO, to study cancer risks caused by "the Electromagnetic Fields." And analyzed all published studies on the subject.

The final cataloging basa "in epidemiological studies showing an increased risk of glioma brain cancer associated with use of mobile phone," said Samet telephone news conference.

This listing means that "there is a risk, and therefore we must closely monitor the relationship between mobile phones and cancer risk," he added.

According to Gerard Lasfargues, deputy director general of Health Security Agency for the Environment (Anses), cataloging the CIRC was until now a step below (ie not classifiable at human carcinogen). The new cataloging is identical to that of glass wool and gasoline vapors.

"It's important to do further investigation into the intensive, long term, mobile phones," he said Christopher Wild, director of the CIRC.

"Until this information is available, it is important to take pragmatic measures to reduce exposure (waves)," he added.

Kurt Straif, the ICRC, explained how to reduce exposure.

"What probably brings more exposure is to use the phone to make calls," he said. "If used for text messages, or a headset for calls is reduced according to him ten times the exposure."

Experts estimate that there is a possible link to gliomas and acoustic neuromas, but are silent on other types of cancers.

Moreover, this panel found insufficient evidence on the risks posed by other electromagnetic fields, such as radar, microwaves, radio or television transmitters or wireless telecommunications.

Cancer Phototherapy


Cancer Phototherapy

A study involving biologists and physicists from the Autonomous University of Madrid (UAM) shows that it is possible to destroy human tumor cells in laboratory culture conditions, using a photovoltaic material volume properties. The procedure, which uses lithium niobate doped with iron (LiNbO3: Fe), has resulted in patent applications for the development of a drug against cancer phototherapy.

The figure shows the effects of exposure of human tumor cells (HeLa) to the Photovoltaic Effect in volume (EFV). Both photographs show the same group of cells before (A) and after (B) of fototratamiento. In (A) shows the cells growing on the crystal of lithium niobate doped with iron before being exposed to visible light. In (B) shows the same cells that have suffered severe structural damage after illumination with visible light. Bubbles (rounded dark structures) on the cell surface indicates that the cells have undergone a process of death called necrosis. The arrows indicate the same cell in both images to facilitate location.
