People who talk on the phone for longer periods of time do not have a higher risk of developing a brain tumor. This has been shown by a study published in the journal. Environment International.
The widespread use of mobile phones and other wireless communication devices has led to concerns that the electromagnetic radiation emitted from them may cause cancer and other diseases. WHO and the EU asked scientists to conduct studies to assess the risks of using phones.
The authors of the COSMOS study used data from more than 250 thousand mobile phone users. Between 2007 and 2013, people from five countries answered questions about their mobile phone use in detail. Their medical records were then reviewed to estimate the incidence of brain tumors. The research showed that the incidence of brain tumors does not depend on the duration of phone use.
In 2011, the World Health Organization Institute for Cancer Research (IARC) classified radiofrequency waves as “probably carcinogenic.” This assessment was based largely on lower quality evidence. The authors of the new study noted that they took into account the mistakes of previous researchers. Their methodology and scope of the study point to a lack of connection between electronic devices and brain tumors. However, they called for more research to be done because the technology used in mobile phones is constantly improving. They will also continue to monitor patients to assess long-term risks.
