390% increased risk for brain tumors
Professor Lennart Hardell, Sweden has made a large study with 1251 cases of brain tumors compared to controls. The risk increased the more years and the more hours per year the phone had been used. The increased risk was 390% for mobile phones and 190% for cordless phones. The greatest risk was for Astrocytoma, the most common malignant brain tumor.
Below you find a brain scan showing a tumor at the right side (blue rounded area), close to were the mobile phone had been held.
This study that was of high scientific quality, differently from most industry-sponsored studies, showed a clear dose-response relationship between the amount of radiation and risk.
This adds importantly to the evidence that mobile phone radiation increases the risk for brain tumors. The evidence, based on a scientific interdisciplinary assessment (and not just epidemiological evidence), has actually long been strong enough to conclude that mobile phones cause brain tumors. Almost only industry-sponsored studies indicate the opposite, while almost all independent studies have reported an increased risk.
This study adds to our conviction that industry-sponsored epidemiological studies finding no tumor risk are faked and should not be considered, see also Corrupt Science at our website. Even if the methodology of professor Hardell is of high quality, epidemiology has such weakness that it cannot be used solely for assessing risk, see “Mobile phone risks are considerably underestimated“.
