現代人手機不離身，整天滑不停，不過隨著健康意識抬頭，有許多人開始擔心長時間使用手機，接觸散發的電磁波會對身體造成不良影響。根據法國研究顯示，即使每天僅使用30分鐘手機，聽起來或許不多，卻會使罹患某兩種腦癌的風險大幅提升2至3倍。
英國《衛報》（The Guardian）引用一份發表於英國《職業與環境醫學》期刊（Occupational and Environmental Medicine）的研究報告指出，每個月使用手機15小時，也就是說每天約使用30分鐘，罹患神經膠質瘤及腦膜瘤的風險就會增加2~3倍。
每月使用手機15小時 腦癌風險高3倍
法國科學家研究顯示，手機重度使用者罹患某兩種腦癌的風險，比幾乎不用手機的人高出許多。平均連續5個月，每個月使用手機15小時，罹患神經膠質瘤及腦膜瘤的風險，比極少使用手機的人，高出2~3倍。
此份研究追蹤447名於2004至2006年間被診斷出來的腦癌患者，分別為253名神經膠質瘤患者與194名腦膜瘤患者。這些患者與892名控制組為研究對象比較。學者發現，長期密集使用手機者，尤其是常使用手機工作者，例如業務人員，罹癌風險較高。受試對象使用手機的年限，最少2年，最多10年，平均是5年。
但是此份研究也有與其他先前類似研究不一致的地方。相較於其它研究顯示腫瘤經常生長在慣用側，也就是習慣接聽手機的那一邊，此份研究則有相反的發現，也就是說，習慣用右耳聽電話的人，腫瘤傾向出現在左邊 。
科技發展成為研究瓶頸
研究人員承認他們面臨一些難以克服的挑戰，包括現實生活中實際使用手機的情形，以及如何排除掉可能影響研究、且也可能造成其它癌症的生活習慣，例如吸菸，還有如何把瞬息萬變的手機科技列入研究考慮。
參與研究的學者承認：「很難明確訂出風險的程度，尤其手機的科技又不斷革新。科技的快速進展提升了手機的使用率，也相對減少了手機散發的電磁波。」學者強調，科學上還需要更多能把快速發展的科技列入觀察、且能容許長期觀察其它可能致癌因素的研究。
WHO列2B級致癌物
隸屬於世界衛生組織（WHO）之下的國際癌症研究所（International Agency for Research on Cancer）於2011年5月31日發布報告，將手機電磁波列為「可能致癌」的2B級致癌物，主要是因為許多研究都認為手機電磁波有可能造成癌症。
然而，過去15年，各國科學家在手機與癌症的關聯上說法不一，有研究認為手機使用與癌症無關，但許多研究都顯示神經膠質瘤與長期、密集的手機使用有所關聯。法國波爾多大學的學者伊莎貝兒巴爾迪（Isabelle Baldi）表示，此份關於腦癌的研究也是屬於這個趨勢，但是結果還需要更多研究支持。
加州柏克萊爭取 手機盒貼致癌警語
《舊金山紀事報》（San Francisco Chronicle）報導，加州柏克萊市議會七月宣布將爭取立法，要求手機零售商在手機包裝上加貼警語，警告使用者，手機會釋放可能致癌的電磁波。柏克萊市計畫尋求哈佛大學法學教授協助草擬警語的用字，以確保此警語符合美國憲法保障言論自由的第一修正案的規定。舊金山市先前已提案失敗，就是因為聯邦法院認同手機產業的論據：強迫業者針對市政府提出質疑的部份加註警語，已違反第一修正案。
美國無線產業協會（The Wireless Association）表示，聯邦政府相關單位已認定手機符合聯邦規範且能安全使用。手機業者也強調，手機的電磁波遠低於聯邦政府的安全上限，而且尚無研究能證明手機電磁波「肯定」與癌症有關。
加州大學柏克萊分校社區與家庭健康中心的喬爾莫斯科維茲博士（Joel Moskowitz），自2009年起就一直在研究手機與癌症的關聯。他表示，手機是「主要新興公共健康風險之一。」
喬爾莫斯科維茲博士建議，如果非得使用手機，使用者可以配戴耳機、使用免持聽筒等方式，並讓身體與手機保持距離。

30 minutes of daily phone brain cancer three times the chance of explosion
Chinese Health Network / reporter Wang Zi Yin / Taipei August 13 2014 00:00 AM
Modern mobile phones leave the body, all day long slide stop, but with the rise of health consciousness, many people began to worry about prolonged use of mobile phones, contact emit electromagnetic waves will cause any adverse effects. According to the French study showed that even the phone using only 30 minutes a day may sound small, but it makes the risk of brain cancer in a two dramatically 2-3 times.
French scientists show that the risks of using the phone 15 hours a month, get gliomas and meningiomas rarely use mobile phones than people, two to three times higher.
British "Guardian" (The Guardian), citing a published in the British "Occupational and Environmental Medicine" journal (Occupational and Environmental Medicine) research report that the use of mobile phones 15 hours a month, that is about 30 minutes a day, glioma and meningioma risk of will increase 2 to 3 times.
Use the phone 15 hours a month three times higher risk of brain cancer
French scientists showed that the risk of cell phone users in a severe two brain cancer, higher than many people almost no cell phone. An average of five consecutive months, the use of mobile phones 15 hours a month, the risk of glioma and meningioma than people who rarely use the phone, higher than the 2 to 3 times.
The study tracked 447 copies in 2004 to 2006 were diagnosed between brain cancer patients, respectively, 253 and 194 neurological patients with glioma meningioma patients. These patients and 892 control group for the study. Scholars have found that long-term intensive use of mobile phones, especially the workers often use the phone, such as higher business, the risk of cancer. Subjects using the phone number of years, at least two years and a maximum of 10 years, an average of five years.
But this study also have copies of previous similar studies with other inconsistencies. Other studies have shown that tumors often grow in the conventional side, which is used to answer the phone the other side, this part studies have found the opposite, that is, the habit of listening to the phone with the right ear of the people, tumors tend to appear to the left compared.
Researchers insurmountable challenges, actually used in real life situations, including mobile phones, and how that may affect the study ruled out, and may also cause other cancers habits, such as smoking and drinking.
Research and Technology Development has become a bottleneck
The researchers admit that they face some formidable challenges, including real-life situations actual use of mobile phones and how that may affect the study ruled out, and may also cause other cancers habits, such as smoking, as well as how to rapidly changing mobile phone Technologies included in the study considered.
Scholars involved in the study admitted: "It's hard expressly set out the degree of risk, especially mobile phone technology and innovation to enhance the rapid progress of science and technology usage of mobile phones, mobile phones emit relatively reduced electromagnetic waves.." Scholars emphasize science need more rapid development of science and technology can be included in observation, and can allow long-term observation of other studies may be carcinogenic factors.
WHO class 2B carcinogen column
National Cancer Institute affiliated with World Health Organization (WHO) under the (International Agency for Research on Cancer) on May 31, 2011 released a report, the mobile phone electromagnetic classified as "probably carcinogenic" Class 2B carcinogen, mainly because many studies have considered the mobile phone electromagnetic waves may cause cancer.
However, over the past 15 years, scientists from various countries in the association on the phone with cancer vary, some studies show that cell phone use and cancer has nothing to do, but many studies have shown that long-term glioma, intensive use of mobile phones has been associated. Scholars at the University of Bordeaux, France, Isabel Baldi (Isabelle Baldi) said that this research on brain cancer were also part of this trend, but the results still need more research support.
California at Berkeley for the phone box stickers carcinogenic warnings
"San Francisco Chronicle" (San Francisco Chronicle) reports, Berkeley, California, in July announced that it would seek parliamentary legislation requiring cell phone retailers on the phone warnings affixed to the packaging, warning the user, the phone will release potentially carcinogenic electromagnetic waves. Berkeley City plans to seek Harvard University law professor assisting in the drafting warnings of words, in order to ensure compliance with the provisions of this warning the United States Constitution guarantees freedom of speech the First Amendment. San Francisco has previously failed proposal, because the federal court to agree with the arguments the mobile phone industry: forcing the industry to challenge for the municipal part of a boxed warning, has violated the First Amendment.
American Wireless Industry Association (The Wireless Association) said that the federal government agencies have identified mobile phones meet federal specifications and can be used safely. Mobile phone industry also emphasized the phone's electromagnetic waves far below the safe upper limit of the federal government, but there is no research to prove that mobile phone electromagnetic "certainly" linked to cancer.
Dr. Joel Moskowitz (Joel Moskowitz) University of California at Berkeley Community and Family Health Center, and since 2009 it has been associated with cell phones and cancer research. He said the phone was "one of the major emerging public health risk."
Dr. Joel Moskowitz suggested that if have to use the phone, the user can wear the headset, handsfree, etc., and let the body and keep the phone away.
