A new study published in JNCI, the Journal of the National Cancer Institute, has detected no substantial change in brain tumour incidence among adults after mobile phone usage sharply increased.
The study investigated the incidence of brain tumours in Denmark, Finland, Norway, and Sweden from 1974 to 2003. Although the use of mobile phones increased sharply in the mid-1990s, no change in incidence trends of tumours were observed from 1998 to 2003 which is when an association between mobile phone use and cancer risk would be expected to show.
