Long-term mobile phone use does not cause brain tumors, a new Danish study published in the journal concludesBritish Medical Journal. The study, the most extensive on the subject carried out to date, is based on 358,403 mobile users who have been studied for more than 18 years.
Under the tutelage of the Copenhagen Institute of Cancer Epidemiology (Denmark), the researchers collected information up to 2007. Thus, they analyzed data from the entire Danish population older than 30 years and born after 1925. The population was divided into users and not mobile phone users before 1995.
In total, 10,729 tumors were registered in the central nervous system between 1990 and 2007. When these figures were restricted to the population that had used the mobile phone for 13 or more years, the percentage was practically the same compared to the population that he was not using his cell phone. “The long follow-up has allowed us to investigate the effects in people who have used the mobile for 10 or more years, and thislong-term use is not associated with an increased risk of developing cancer“They have concluded.
Future studies will also try to rule out increased risk, both mild and moderate, in small groups of highly active users for periods longer than 10 or 15 years.
Previous studies on this topic had not reached an accurate conclusion. In fact, the International Agency for Research on Cancer (IARC) recently categorized radio frequency electromagnetic fields emitted by mobile phones as probably carcinogenic to humans.
