Radiofrequency radiation from cell phones and cordless phones can cause gliomas

Michael Carlberg and Lennart Hardell at Örebro University, Sweden in 2017 released a report saying that radiofrequency (RF) radiation from cell phones and wireless phones should be classified as a human carcinogen causing glioma. Use of cell phones is extremely common. In many countries, wireless communication has replaced the traditional landline based communication. However, this report reveals that exposure to radiofrequency (RF) radiation from cell phones and wireless phones can double the risk of glioma – a malignant brain tumor.

The following is the abstract of the report.

Objective. Bradford Hill’s viewpoints from 1965 on association or causation were used on glioma risk and use of mobile or cordless phones. Methods. All nine viewpoints were evaluated based on epidemiology and laboratory studies. Results. Strength: meta-analysis of case-control studies gave odds ratio (OR) = 1.90, 95% confidence interval (CI) = 1.31–2.76 with highest cumulative exposure. Consistency: the risk increased with latency, meta-analysis gave in the 10+ years’ latency group OR = 1.62, 95% CI = 1.20–2.19. Specificity: increased risk for glioma was in the temporal lobe. Using meningioma cases as comparison group still increased the risk. Temporality: highest risk was in the 20+ years’ latency group, OR = 2.01, 95% CI =1.41–2.88, for wireless phones. Biological gradient: cumulative use of wireless phones increased the risk. Plausibility: animal studies showed an increased incidence of glioma and malignant schwannoma in rats exposed to radiofrequency (RF) radiation. There is increased production of reactive oxygen species (ROS) from RF radiation. Coherence: there is a change in the natural history of glioma and increasing incidence. Experiment: antioxidants reduced ROS production from RF radiation. Analogy: there is an increased risk in subjects exposed to extremely low-frequency electromagnetic fields. Conclusion. RF radiation should be regarded as a human carcinogen causing glioma.

手机和无线电话的射频辐射能够导致胶质瘤

瑞典Örebro大学的Michael Carlberg和Lennart Hardell在2017年发布了一份报告，指出手机和无线电话的射频（RF）辐射应归为导致神经胶质瘤的人类致癌物质。 使用手机是非常常见的。 在许多国家，无线通信取代了传统的基于座机的通信。 然而，这份报告显示，暴露于手机和无线电话的射频（RF）辐射可能会使神经胶质瘤（恶性脑肿瘤）的风险增加一倍。以下是稍微编辑的摘要，使其更容易理解。

目的。 Bradford Hill从1965年关于关联或因果关系的观点被用于胶质瘤风险和使用移动或无绳电话。方法。所有九个观点根据流行病学和实验室研究进行评估。结果。强度：病例对照研究的综合分析给出了风险比（OR）= 1.90,换句话说，暴露于手机和无线电话可能会增加胶质瘤的风险90％。累积暴露风险最高。一致性：风险随潜伏期增加，综合分析在10年以上潜伏组OR = 1.62。特异性：胶质瘤的风险增加在颞叶。使用脑膜瘤病例作为比较组仍然增加了风险。时间：无线电话最高风险在20多年的潜伏组，OR = 2.01。生物梯度：无线电话的累积使用增加了风险。合理性：动物研究显示暴露于射频（RF）辐射的大鼠的胶质瘤和恶性神经鞘瘤的发病率增加。来自RF辐射的活性氧（ROS）的产量增加。一致性：胶质瘤的自然史有变化，发病率上升。实验：抗氧化剂降低RF辐射下的ROS产量。类比：暴露于极低频电磁场的受试者的风险增加。结论。射频辐射应被视为导致神经胶质瘤的人类致癌物质。
