Long-term use of both mobile and cordless phones is associated with an increased risk for glioma, the most common type of brain tumor, the latest research on the subject concludes.
The new study shows that the risk for glioma was tripled among those using a wireless phone for more than 25 years and that the risk was also greater for those who had started using mobile or cordless phones before age 20 years.
“Doctors should be very concerned by this and discuss precautions with their patients,” study author Lennart Hardell, MD, PhD, professor, Department of Oncology, University Hospital, Örebro, Sweden, told Medscape Medical News.
Such precautions, he said, include using hands-free phones with the “loud speaker” feature and text messaging instead of phoning.
The study was published online October 28 in Pathophysiology.
