Do mobile phones significantly increase the risk of brain cancer?

There was no indication of higher brain tumor risk among persons who had used hand-held cellular phones compared to those who had not used them. More importantly, there was no evidence of increasing risk with increasing years of use or average minutes of use per day, nor did brain tumors among cellular phone users tend to occur more often than expected on the side of the head on which the person reported using their phone.

While making strong claims that “There is a growing and statistically significant body of evidence that brain tumours…are linked with “heavy” and “prolonged” mobile phone use…”, the review is inexpert and incomplete, containing a number of factual errors. In particular, Khurana fails to consider the relative scientific quality of different studies. This produces an unbalanced analysis of the literature, which is also selective in support of the author’s claims.
