频繁使用手机患脑瘤?

2019-05-25 10:06 来源:科技日报

[摘要] 用手机会导致患上脑瘤?这一点科学家并没有做出肯定性答复。然而,近日意大利最高法院却给出“肯定”的判决。有意思的是,2012年,意大利最高法院也曾判处过一例因使用手机导致脑瘤而获赔案件。

  用手机会导致患上脑瘤?这一点科学家并没有做出肯定性答复。然而,近日意大利最高法院却给出“肯定”的判决。有意思的是,2012年,意大利最高法院也曾判处过一例因使用手机导致脑瘤而获赔案件。

  来自法新社的报道称,在电信公司工作了15年的罗伯特·罗密欧,由于每个工作日要使用3—4个小时的手机,2010年被诊断出患上脑瘤。

  手机的辐射是否增加了人们患脑瘤的几率?这一问题从移动电子设备发展的最初阶段便一直被争论不休。那么,脑瘤到底和打手机有没有关系?应该怎么看待其“致癌可能性”?得了脑瘤具体意味着什么呢?又该如何防范?听专家如何答疑释惑——

  流行病学上暂无依据 

  手机辐射被认为是脑瘤增长背后的最大原因,是源于2011年国际癌症研究机构(IARC)将手机定义为“可能致癌物”。

  据IARC发布的评估报告称,无线通信设备产生的无线电频率电磁场有可能是一些人患癌症的原因,而这种电磁场可能增加患神经胶质瘤的风险。到目前为止,手机致癌还只停留在“可能”层面上。

  “手机辐射会不会引起脑瘤,一直存在争议,”天津肿瘤医院颅脑肿瘤科主任李文良教授在接受科技日报记者采访时表示,国外科学家也利用动物实验和人群研究来评估手机辐射的致癌性,但截至目前,流行病学上还没有任何证据证明手机与脑肿瘤风险增加有关。

  李文良认为,手机辐射与脑瘤两者之间可能会有联系,但是联系不大。“因为中国自上世纪90年代开始,手机使用呈爆炸性增长,但脑瘤的发生率却没有出现相对应的‘爆发性增长’,增长速度和手机出现前数量并没有太显著的差别。”

  但中国工程院院士、复旦大学附属华山医院神经外科主任周良辅教授却给出了这样一组数据,近30年来,上海地区脑瘤年发病率逐年上升,而这30年恰恰是上海手机普及率井喷的一段时期。

  与上世纪80年代相比,男性胶质瘤的发病率提高了1.2倍,女性提高了2.2倍。统计数据显示,我国目前脑瘤年发病率为6.2/10万人,上海地区为7—8/10万人。而在儿童肿瘤患者中,胶质瘤排名第二,仅次于白血病。周良辅分析认为,除了近年来医疗诊断水平与患者就诊率提高之外,频繁用手机增加患病风险。

  据介绍,有研究证明频繁使用手机10年以上、习惯将手机放在枕头边上、长时间随身携带等,都会增加罹患恶性脑肿瘤的风险。而青少年由于耳朵和颅骨比成年人更小、更薄,他们在使用手机时,脑部吸收的辐射比成年人要高出50%。

  辐射等于把脑子煮熟了? 

  英国学者曾经做过一个试验,把手机放到线虫的抚育箱里,手机发出的电磁辐射作用一段时间后他们发现,线虫就像用水煮过一样。有专家表示:“尽管颅骨可以屏蔽一部分微波,但电磁辐射的穿透力很强,微波穿透颅骨后作用于脑子,等于把脑子煮熟了。”

  对“辐射等于把脑子煮熟了”这一说法,李文良不以为意,他表示,手机释放的是非电离辐射,与x、γ射线不同,通常只会产生少量热量,临床上会出现头晕、头疼的症状,而不会改变人类的DNA。

  目前国际上还没有一个科学的方法能证明脑瘤是由于电磁辐射引起的,但电磁辐射如果超过一定强度、持续一定时间就对人体有害,这是国际上公认的。

  因为使用手机时,人体成了天线的一部分,而电磁辐射会对人体健康产生影响,是肿瘤发病原因之一,这也已经是有定论的。决定影响大小的一个重要因素就是人体所接受和吸收的辐射剂量大小,因为人体自身对电磁辐射有一定的耐受力,并不是一接受电磁辐射就会出现状况。当人体接触的辐射剂量较小时,其自身免疫系统能够承受;比如有人长时间打电话会出现头疼、头晕、皮肤刺痛以及注意力不集中等现象,甚至有人会因其影响睡眠,但这种症状还不能将手机与肿瘤划上等号,一般来说只要避免长时间接触手机或者减少打电话时间,症状都能自然减轻消失。不能忽视的是,当辐射剂量过大或者长期接触时,就有可能会对人体产生一些损害。尤其是儿童,其承受能力较成人要弱得多。因此,建议家长应尽量避免小孩子接触电磁辐射源。

  多种原因导致脑癌高发 

  世界卫生组织承认,手机会带来神经胶质瘤和听觉神经瘤等不利影响,但是否会导致其他癌症至今尚无定论。

  文献显示,脑肿瘤在人类十大常见肿瘤中的致死和致残率高居第二和第四位,而胶质瘤则是最常见的脑肿瘤,约占45%—50%。

  “从临床统计来看,胶质瘤在各个年龄层都能发现,目前胶质瘤的发病机理尚不明确,但胶质瘤作为一个典型的恶性肿瘤,跟生物因素、遗传因素、环境因素,例如不健康的生活方式等密切相关。”李文良认为,近几十年脑瘤发病率呈上升趋势,除了这些危险因素外,与检查手段提高和公众意识增强等密不可分。

  据了解,相对于其他类型的癌症,脑胶质瘤早期的临床症状并不十分典型,很多患者直到症状非常明显或无法忍受时才选择就诊。

  李文良透露,脑胶质瘤的早期症状是头疼,接打手机时间过长也会出现头疼,不过此头疼非彼头疼。数据显示,大约有30%的脑胶质瘤患者表现为头痛,其中约有70%的人头痛会逐渐加重。而且,脑瘤的头疼一般出现在夜间和晨起的时候,并且伴有阵发性或者搏动性头疼,到后期就会转变成持续性剧烈头疼。需要注意的是,大脑胶质瘤通常表现为前额的疼痛,而小脑胶质瘤则多表现为枕部和颈部的疼痛。若肿瘤短期内明显进展或者出现瘤内出血,患者会出现急性头痛发作,此时必须引起重视。对于普通人而言,如果长期头痛,经济条件又允许,每年体检时宜增加头颅磁共振检查,对于早期发现颅内病变有很大帮助。

  头颅CT是筛查颅内病变的“第一道屏障”,通常,在CT发现异常情况后,医生会建议患者接受头颅磁共振(MRI)检查。目前认为,MRI是确诊脑胶质瘤的主要检查手段。若MRI仍然难以确诊,PET/CT是一个很好的补充检查措施。

  一场没有结论的争论 

  手机辐射究竟对人体能造成多大伤害,至今没人能给一个明确的说法。尽管截止到目前,尚无充足证据支持手机辐射会增加脑肿瘤的风险,但是想要完全排除风险的可能性也并非那么容易。

  大多数科学家认为,即使日常生活中接触的电磁辐射对健康有一定影响,这种影响与其他常见的健康威胁相比也很可能是非常小的,不必为此感到恐慌。不过,美国食品药品监督管理局、美国联邦通信委员会等机构和中国科学家还是给出了一些个人降低手机电磁辐射暴露的建议:首先,应尽量减少每次使用手机的时间,以及每天使用手机的次数;其次,在不使用手机时,可以将手机关机并放到远离人体的地方,千万不能让手机“陪睡”;另外,建议经常使用手机及长时间通话者,多使用免提或者耳机方式,特别对于那些手机辐射敏感的人群,采用耳机方式会消除用户的自觉症状,在不使用免提时尽量用左耳接听电话并且左右耳接替接听;在电话放在口袋里时,尽量将电池那一面背向人体。尤其需要注意的是,避免儿童过早使用手机。

  现在,全球针对手机辐射与人体危害的更多相关大样本研究正在进行中,相信当这些研究结果揭晓时,我们会对这一问题有更加深入的认识和了解。
