This comprehensive rat study found no increased brain tumor risk from 860 MHz radiation at phone-level exposures over nearly two years.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to 860 MHz radiofrequency radiation for up to 22 months to see if it could cause or accelerate brain tumors. The study found no statistically significant increase in brain tumors or other cancers from the RF exposure, even when combined with a known cancer-causing chemical. This was a large, well-controlled study using 900 rats with extensive tissue analysis.

Quick Questions About This Study

A major 2001 study found no evidence that 860 MHz radiofrequency radiation causes brain tumors in rats. Researchers exposed 900 rats to this frequency for 22 months and found no statistically significant increase in brain tumors or other cancers compared to unexposed controls.
This large animal study using 860 MHz radiation (similar to early cell phones) found no increased brain cancer risk. Even when combined with known cancer-causing chemicals, the radiofrequency exposure did not promote or cause brain tumors in laboratory rats over 22 months.
Research on 860 MHz radiofrequency radiation showed no effect on tumor development in any body tissues. The 2001 study tracked 900 rats for up to 22 months and found no significant differences in tumor number, size, location, or type between exposed and control groups.
Studies show no significant cancer risks from 860 MHz radiofrequency exposure. A comprehensive 2001 animal study found no increased rates of brain tumors, spinal cord tumors, or other cancers, even with prolonged exposure lasting up to 22 months in laboratory conditions.
Research on 860 MHz radiation (used by some cell towers) found no impact on cancer rates in animal studies. A large 2001 study exposed rats to this frequency for nearly two years and detected no statistically significant increase in any type of cancer or tumor.
