NTP TECHNICAL REPORT ON THE TOXICOLOGY AND CARCINOGENESIS
STUDIES IN B6C3F1/N MICE EXPOSED TO WHOLE-BODY RADIO FREQUENCY RADIATION AT A FREQUENCY (1,900 MHz) AND MODULATIONS (GSM AND CDMA) USED BY CELL PHONES

We have read these two reports with interest. They show increased incidence of malignant
schwannoma in the heart and brain glioma in male rats exposed either to GSM-modulated or
CDMA modulated cell phone radiofrequency (RF) radiation for two years. There are also
increased incidences of some other tumor types and diseases. We discuss in the following
some of the major findings.

The reports the results on schwannoma and glioma are of special concern since they
corroborate human epidemiology findings. Thus, it is noteworthy that similar tumors were
found in the NTP study as in epidemiological studies on human use of wireless phones;
mobile phones or cordless phones (DECT). Malignant schwannoma in the heart is a similar
type of tumor as vestibular schwannoma in humans, also called acoustic neuroma, although
acoustic neuroma is usually benign and may rarely undergo malignant transformation.

In the following we give an updated evaluation on the scientific evidence for increased risk
for glioma and vestibular schwannoma (acoustic neuroma) associated with use of wireless
phones. In our opinion also certain aspects on human epidemiology on this issue need to be
further clarified and elaborated in the NTP report.

Our study group has since the end of the 1990’s published results from case- control studies
on use of wireless phones and brain tumor risk (Hardell et al 1999). An increased risk for
brain tumors was found for ipsilateral use of mobile phones, the same side of the brain as the
phone was used. A statistically significant increased risk was published for malignant brain
tumors (Hardell et al 2002) and vestibular schwannoma (Hardell et al 2003). Further scientific
evidence on the association has more recently been discussed by Carlberg and Hardell (2017).
