Ronald B. Herberman, M.D., says he wants to "err on the side of being safe" from cancer. Many studies have found no link between cell phone use and cancer. Dr. Herberman says he is basing his action on unpublished data from research that is not complete. He says children should use cell phones only for emergencies. He urges adults to keep the phone away from the head and use the speaker phone or a wireless headset. The Associated Press wrote about Dr. Herberman's memo July 24. What Is the Doctor's Reaction? So many things we do and are exposed to might possibly cause cancer. Yes, cell phones may be one of them. But how should you respond each time a new cancer risk possibility arises? At this time, the evidence about cell phone use and cancer is not conclusive. There is no definitive advice. Therefore, experts will continue to debate how much you should use your cell phone and whether even talking on it all day long increases your cancer risk. It's quite remarkable how differently each of us views risks to our health. For instance, some people who will never travel by plane because of fear of a crash don't wear a seat belt when riding in a car. Some experts strongly believe that the medical evidence will show that talking on a cell phone for many hours each day over a long term is harmful. These are thoughtful, well qualified scientists who have reached this conclusion. These experts are especially concerned about cell phone use in children. Here are the essential elements of their position: Cell and wireless phones give off electromagnetic radiation. Electromagnetic fields have the potential to penetrate more deeply into children's brains than into adults' brains. The brains of younger children are smaller, developing more rapidly, and have softer tissue. Electromagnetic radiation is more likely to have greater affects on softer, smaller, developing brains. These statements about electromagnetic fields are likely true. However, medical studies done so far don't show that the amounts of radiation emitted by cell phones cause harm.  What Changes Can I Make Now? If you believe that cell phones do pose a health risk and you would rather be cautious, here are recommendations from the Pittsburgh Cancer Institute: Limit cell phone use. (The institute actually advises that children use cell phones only for emergencies.) When using a cell phone, keep it some distance from your head. Just moving it away two inches decreases the electromagnetic force by more than one-half. Use devices that help decrease your exposure to electromagnetic radiation. Examples include speaker phones, headsets and ear piece attachments. If you need to wear your cell phone, put the keypad toward you and the back away from you. Also put the phone on "flight" or "off-line" mode. During longer conversations, switch the phone from one side to the other frequently. Text message whenever possible. This shortens the time and keeps the phone farther away from the body. Choose a phone with a low SAR (Specific Absorption Rate). This measures the strength of the magnetic field given off by the phone. What Can I Expect Looking to the Future? Human studies done so far do not show an association of increased health risk to cell phone use. The experts who strongly believe in the cell phone and cancer link acknowledge this. However, they argue that the studies have only evaluated people over a relatively short period of time. They are convinced that the adverse health results will show up in the future. But it may take another 10 or even 20 years to prove it. *^_ 3 QRSpq@Ah;bhN 'h;b0JB*CJOJQJ^JaJph333h;bCJaJ,jh;bB*CJOJQJU^JaJph333#h;bB*CJOJQJ^JaJph333h;bCJOJQJ^JaJ*^NB $d $Ifa$=kd$$IfK$L$ 6 -6-34aFkd#$IfK$L$ 6 -6-2 234a $d $Ifa$K$$d $Ifa$gd;b$d $Ifa$gd;bA 4 %c6PQRS:kdk$$$IfT!634aT$d $Ifa$gd;b$ & Fd dd$If[$\$a$ $d $Ifa$STq u/q@A$ & Fd dd[$\$a$gd;b $d a$gd;b ,1h/ =!"#$% #Dd  S A@jDC684732A6AAF89BEBC70A613AED4F5Harvard Health Publications//Harvard Medical School Rc"Y_lo?"D F7"Y_loJFIFddDuckyFAdobed    vv  !1"AђTUQa2B4tq#3VR$5bS !1AQaq"2BRSb#r3s ?j+!8& a"&UUAUUSDM>moDG~CzFD|>moDG~CzFD|>moDG~CzFD|>m)2d@ Bh"azuꈺ"nSfM;#DF"4Dh#DF"Jo5h3I5_U1KQ\;<5YOV_DL'؜㐫q =4>b얛4U 苶ˡ@w#S0&C]M_~IHk6ԓtS}-lu3'2w[(#DFB_8*tl5lw-c2ArKB<RTS]龴9ZiuF-v|*(j\VS9GE]mnY-1bU/CWkφJ_b??PƎữҟ؏_ne#CWh>)Y}vn{sܻx<z*=zvn/ɹkǐh6 "VylU}6-;K<Қ FНyNȑDwܗ~#W{B7Pp oi$BsuFQM) s\Hŝ[NRNNs8̰>qKy+|[?kK)k24fU-z%j̛oWE׻J"@sL^yw*YC_$T>:XoBԢeuQ\^ooBW121a޴u JCK8w|,dzտ%<ŝ0%T*3ʼPe őOMo+LN#uVb e2 uRX/"{kVnSeAm{f=OXI Ѕ>,z ŝoùW?;Zu#W=jAM}}8s g h2Ky2豤 D|ڛ@r|H ܾ&0NjL=qy"k+h+Qab[ K›%(` ˁl[:21K©i=6/ f)"ʞ%1ı}rI9)x.gtZ2iǍC3j?꽲4 8傇[՟ڨ=E¨m9V2<)ko  ;6ú]"k&?}oqLg> 2;r&LhnMxH/t[igD%ʣr 8YnIe?orMrbcI![(qH,Ȏ8*Nq'!튐%Oev KuT֘u0mm}>WGT,}~_s[Sn_48h*_~M#X$.v@{~jL0>kaXQ`xy$ʼ{qņ|tb0Ύlly\VԷA(_2ml:a!,%!Ź*37GƂ1%ͤ$& n'q{~Т5E-A٢1 ]A~70:"tIl\-Fcɏ{'UnD̙c-UYp@A%ۯ&~NP_hwnO4NQӞ[lnu.];-0)9lHrEjjKMu Cb;U#s|?ǖUǟ 9ZhV !GW8@|u7ݾs 3;UlK~N3J|cѹ5hަGL.DbQJrYEBp6{h<XyPK L%K͵Gb4~r9jOVQ|{sDmL~S H轾[w=צЦZ%6/(7=NU}Z@4ĥrvu,7dŔcU. +%Jh>s-W~ʻeq১yXFaGP*Sgmd[2yȤF}5AqQ/ct+o!Xچ{IHĄ3C nbfRV+h "h˦ڌI/sz%qopwQG.
