In this study, further analyses on the database of a Swedish case-control study (see publication 1015) were performed on the risk of brain tumours and the use of cellular telephones, exposure to ionizing radiation and chemicals.
|Group 1||tumor localization brain hemisphere, ipsilateral cellular phone use|
|Group 2||tumor localization brain hemisphere, contralateral use|
|Group 3||tumor localization brain hemisphere, ipsilateral and contralateral use|
|Group 4||tumor localization frontal, frontoparietal, parietal, or parieto-occipital, ipsilateral use|
|Group 5||tumor localization frontal, frontoparietal, parietal, or parieto-occipital, contralateral use|
|Group 6||tumor localization frontal, frontoparietal, parietal, or parieto-occipital, ipsilateral and contralateral use|
|Group 7||tumor localization temporal, occipital or temporoparietal, ipsilateral use|
|Group 8||tumor localization temporal, occipital or temporoparietal, contralateral use|
|Group 9||tumor localization temporal, occipital or temporoparietal, ipsilateral and contralateral use|
Only results concerning exposure to electromagnetic fields are listed within the EMF-Portal.
No association was found with occupations with potential exposure to extremely low-frequency electromagnetic fields (eg., electrician, electronics work, lineman, or telecommunication work) and the risk for brain tumor. The use of a video display unit did not increase the risk. An increased risk for brain tumor was found for ipsilateral use of cellular phone in the anatomic area with highest microwave dose.
