The INTERPHONE study examined more than 5,000 people with brain tumors and a similar group without tumors across 13 countries, finding no overall link between brain-tumor risk and cell-phone use, call frequency, or longer call times.
Notes on verification
Confirmed by multiple independent, credible sources including scientific/press coverage of the INTERPHONE study (CORDIS, Medscape, IEEE Spectrum). Findings align with the well-documented, multi-country study design and its widely reported conclusions.
