Scientific Cell Phone Study: Can Cell Phones Cause Cancer?

Hand radiation triggers tumors in rats
For a long time, there have been different views about whether using a cell phone increases the risk of some cancers. A recent study now comes to the conclusion that cell phone frequencies could cause two types of tumors.

Today almost every adult has a cell phone and for many a life without their phone is almost unthinkable. For this reason, it is important to know whether cell phones endanger our health and can cause cancer through their frequencies. There have been several studies on this topic, some with conflicting results. The American government has now commissioned some scientists to determine whether there is a risk to cell phone frequencies for our health. In fact, researchers from the National Institute of Environmental Health Sciences noticed a weak association between cell phone radiation and two types of tumors. However, these results only related to rats. The results of the study have now been published as a communication.

Study examines the impact of cell phone radiation on 2,500 rats and mice
The researchers carried out an experiment with 2,500 rats and mice. This should show the connection between cell phone radiation and the development of tumors. The animals were exposed to radio frequencies every ten minutes. The doctors explain these to the radiation emitted by our cell phones. In total, the test animals were exposed to radiation for nine hours a day. As a result, the scientists were able to determine that there was a connection between the radiation and brain tumors or tumors in the heart. It is still completely unclear whether these results can also be transferred to us humans. However, with so many people using a cell phone every day these days, the impact on public health could be huge, the authors add.

Studies in humans are problematic
It is problematic to investigate whether people experience health disadvantages from the radiation from cell phones because studies on people are less controlled, the experts say. People are just not as easy to study in laboratories as mice. Researchers had already asked people with brain tumors to remember the amount of cell phone use. Then they compared the data with the records of healthy people. However, it is not easy for many people to remember exactly when and how long they used their phone, the scientists explain.

Male rats appear to be more susceptible to the development of tumors
In the latest rodent study published on Friday, researchers from the National Institute of Environmental Health Sciences irradiated rats with high doses of radiation. They repeated this process every day for two years. Afterwards, they compared the values ​​of the animals with rats that were never exposed to radiation, the experts explain. The scientists then examined how many animals had developed tumors in the brain or nerve cells of the heart. The researchers found that two percent to three percent of the one hundred male irradiated rats developed brain tumors. For comparison, no tumors could be found in the control rats, say the doctors.

The number of female rats that developed these cancers was lower. Only about one percent of the animals had such tumors. However, these could also have been caused by chance, the researchers say. Between two percent and seven percent of the irradiated male rats developed tumors on the heart. In female experimental animals, the value was only about two percent. If the female rats were not irradiated, no tumors could be found, the authors add. It is still unclear why the male rates in the study contracted cancer more often than the female animals. Male rats seem to be generally more susceptible to the development of tumors, the doctors suspect. (as)
