According to a Danish study of mobile phone users, mobile phones are being falsely accused of increasing the chance of developing cancers of the nervous system.

In recent years, concerns have been raised that mobile phone use might be linked to certain types of cancer. With more than 5 billion people using mobile phones worldwide for both personal and professional use, this has become a topic of great alarm. However, a recent Danish study, which was published in October 20, 2011’s British Medical Journal, does not support these claims.

The study looked at reports from Denmark’s centralized cancer registry in addition to mobile phone subscriber records. By focusing on Danes over the age of 30, the study utilized 358,403 records from 1990 to 2007. In a comparison between adult cell phone users and nonusers, the study found that there was no higher incidence of any type of cancer in those who used mobile phones.

The team behind this research believes that by using data that is already available rather than interviewing phone subscribers, their research is more reliable than previous studies. This belief is founded in the idea that phone subscriber recall can be unreliable or incomplete during interviews.

However, there are people who are hesitant to take this study at face value. Anders Ahlbom, a professor at the Karolinska Institute in Stockholm, is skeptical about this data, citing frequency of usage as one of the many factors the study failed to take into consideration. However, he stated, “The absence of a trend in the incidence of brain tumors in national statistics is reassuring,” adding, “Continued monitoring of health registers and prospective cohorts is warranted.”
