Increase in brain tumors is not attributed to mobile phone use
the Oncology Nurse Advisor take:
New research from the University of Auckland found that risk of brain cancer is not increased by mobile phone use. Concerns have been raised about whether use of mobile phones can increase the incidence of brain cancers.
Previous studies from around the world reported findings that showed no risk or a slightly increased risk, with some studies suggesting a substantial risk.
The New Zealand team examined the frequency of brain cancers in total and in subtypes highlighted in other studies, using data from the New Zealand cancer registry.
These investigators found no general increase. They did see, however, was a decrease of approximately 1% per year in people 10 to 69 years. Based on their findings, they report previous findings of large increases in risk are likely to be incorrect.
However, they concede that a study of this type cannot exclude a small risk, or one limited to certain subtypes of cancers, or a risk arising after more than 15 years of phone use.
The research team cannot explain the decrease in brain cancers in New Zealand. An increase in some types of brain cancer among people 70 years and older—in New Zealand and other countries—may be related to improved diagnosis.
