A large scientific study of rats suggests that there is a clear link between using a cell phone and cancer.
Repeated use of mobile phones is regularly accused of causing cancer, especially in the brain. However, scientists working on this link have difficulty finding sufficient evidence.
The last study is American and has been carried out for ten years. Conducted as part of the US National Toxicology Program, this study was highlighted in rats the "obvious" relationship between the use of mobile telephony and the emergence of cancers.
Shown to radio waves similar to those emitted by cell phones, male rats had a higher risk of developing heart cancer, brain tumors and adrenal glands. In contrast, in rodents, the symptoms of cancer were not as pronounced.
If exposure to rodent radiation goes far beyond what we are exposed to every day, scientists are convinced that the study is conducted well enough to conclude that there is a real relationship between exposure to telephone waves and the risk of cancer. But because man is exposed to these waves only in the local areas of the body (groin, when we have a phone in our pocket, the head when we call), The effect of the phone is difficult to reproduce in animals that are exposed to the whole body.
For everything "although the exposure power levels are much higher than typical patterns of human use", Scientists believe that"the results of this study remain valid with respect to current exposures"Especially when we are exposed to waves emitted by several mobile phones (at work, in public transport, in public places, etc.).
Finally, it should be noted that the research focused on 2G and 3G wireless signals, which are still very often used by mobile phones despite the emergence of 4G and Wi-Fi.
Recall that you can choose a cell phone based on the waves it emits, taking into account SAR (specific absorption coefficient) or SAR, in English (specific rate of absorption). French legislation has been applying the DAS index for less than 2 W / kg since 2003, but there are even some laptops that do not emit more than 0.7 W / kg.
