<ul><li> 1. Do Cell Phones Cause Cancer? Lakshmi Jagannathan 11/30/05</li></ul> <p> 2. How Cell Phones Work </p> <ul><li>Making a call: Voice Radio Waves Base Station </li></ul> <ul><li>Receiving a call: Base Station Radio Waves Voice </li></ul> <p> 3. Radiowaves </p> <ul><li>Radiowaves- Radiofrequency energy </li></ul> <ul><li>Form of Non-Ionizing Radiation </li></ul> <ul><li>Ionization:High levels of energy that cause damage to biological tissues, including DNA </li></ul> <ul><li><ul><li>Heats Tissue </li></ul></li></ul> <ul><li><ul><li>Damages Tissue </li></ul></li></ul> <ul><li><ul><li>Causes Diseases like Cancer </li></ul></li></ul> <ul><li><ul><li>Ex:Medical X-Ray=High Doses Pose Risks </li></ul></li></ul> <p> 4. Electromagnetic Spectrum 5. When did this concern start? </p> <ul><li>1993: David Reynards Lawsuit </li></ul> <ul><li><ul><li>Claimed that wifes fatal brain tumor caused by cell phones </li></ul></li></ul> <ul><li><ul><li>Appeared on Larry King Live </li></ul></li></ul> <ul><li><ul><li>Results: Case Dismissed for lack of scientific and medical evidence </li></ul></li></ul> <ul><li><ul><li>Significance : First to enter public domain</li></ul></li></ul> <p> 6. Second Major Trial </p> <ul><li>2000:Chris Newmans $800 million lawsuit </li></ul> <ul><li><ul><li>Neurologist:Malignant tumor behind right ear </li></ul></li></ul> <ul><li><ul><li>Court/Judge:23-page ruling or textbook that shows the courts emphasis on scientific evidence </li></ul></li></ul> <ul><li><ul><li>Result:No evidence that cell phone caused cancer </li></ul></li></ul> <ul><li><ul><li>Significant: Another Major Setback for people who claim that cell phones cause cancer </li></ul></li></ul> <p> 7. Animal Testing </p> <ul><li>1997:Test on Mice in Royal Adelaide Hospital, Australia </li></ul> <ul><li>Procedure: 200 mice- 100 exposed to pulsed digital phone radiation; 100 controls </li></ul> <ul><li>Result: </li></ul> <ul><li><ul><li>Significant increase in B-cells (implicated in 85% of all cancers) </li></ul></li></ul> <ul><li><ul><li>After 18 months, exposed group had twice as many tumors </li></ul></li></ul> <ul><li>Problem :Mice sometimes exposed to 20 hours of radiation!!Therefore, not very comparable to humans </li></ul> <p> 8. Significant Studies/Tests </p> <ul><li>Experiment :Patients with brain cancer were compared to patients without brain cancer, in terms of their past cell phone usage </li></ul> <ul><li>Description : </li></ul> <ul><li>1)Stockholm:</li></ul> <ul><li><ul><li>233 brain cancer patients diagnosed between 1994 and 1996 to 466 controls </li></ul></li></ul> <ul><li>2)New York, Providence, and Boston:</li></ul> <ul><li><ul><li>Conducted by American Health Association </li></ul></li></ul> <ul><li><ul><li>469 brain cancer patients between 1994 and 1998 to 422 controls</li></ul></li></ul> <p> 9. Significant Studies/Tests </p> <ul><li>Description </li></ul> <ul><li>3) Phoenix, Boston, and Pittsburgh: </li></ul> <ul><li><ul><li>Conducted by U.S National Cancer Institute</li></ul></li></ul> <ul><li><ul><li>782 cancer patients between 1994 and 1998 with 799 controls </li></ul></li></ul> <ul><li><ul><li>4)Denmark:Largest Cohort Study</li></ul></li></ul> <ul><li><ul><li>Attempted to Link 420,095 users</li></ul></li></ul> <ul><li><ul><li>between 1982 to 1995 to Danish </li></ul></li></ul> <ul><li><ul><li>Cancer registry </li></ul></li></ul> <p> 10. Results of Studies/Tests </p> <ul><li>Three Main Results: </li></ul> <ul><li>1) Patients with brain cancer did not report more cellular phone use overall than the controls.All types of cancers and all locations were considered </li></ul> <ul><li>2) None of the studies showed a "dose-response relationship:Brain Cancer didnt increase with more cell phone usage </li></ul> <ul><li>3)No Clear Link between the side of the head that the brain cancer occurred and where the cell phone was used </li></ul> <p> 11. Who Regulates Cell Phones? </p> <ul><li>FDA (Food and Drug Administration): </li></ul> <ul><li><ul><li>Responsible for monitoring electronic products to ensure acceptable amounts or raditation emission </li></ul></li></ul> <ul><li>FCC (Federal Communications Commission) </li></ul> <ul><li><ul><li>Places Limits on Radio emission waves from all mobile phones </li></ul></li></ul> <p> 12. What can we make out of all of it? </p> <ul><li>Cell Phone:Relatively New Technology </li></ul> <ul><li>Lack of Ionizing Radiation and Low Energy Level Emitted:Unlikely that this device causes cancer </li></ul> <ul><li>Several well-designed and studies found no link between cancer and cell phone</li></ul> <ul><li>Some recent studies found a POSSIBLE link to acoustic neuroma, a rare tumor that develops behind the ears not a valid claim! </li></ul> <ul><li>FDA says:highly impossible </li></ul> <p> 13. Summary </p> <ul><li>John E. Moulder, Ph.D., acancerresearcher and professor of radiation oncology at the Medical College of Wisconsin says: </li></ul> <ul><li><ul><li> From the physics standpoint [only 6/10 of a watt emitted even if cell phone is right against the skull], biological effects from mobilephonesare somewhere between impossible and implausible. </li></ul></li></ul> <ul><li><ul><li>"Some people think the power emitted by thephonesis so low, it's a silly thing to research. But I think it remains a legitimate area of study."</li></ul></li></ul> <p> 14. Remedy? </p> <ul><li>BioPro Technology EMF protection- for all household products </li></ul> <ul><li>Harmonizes frequencies and makes it less dangerous </li></ul> <p> 15. Video- Dangers of EMF </p> <ul><li>Dangers of EMF and Cell Phones: </li></ul> <ul><li><ul><li>www. emf -health.com </li></ul></li></ul> <p> 16. Reference </p> <ul><li>History of Cell Phones:http://www.eden.rutgers.edu/~cang/history/public.html </li></ul> <ul><li>Dr. Moulders Research:Consumers' Research Magazine </li></ul> <ul><li>Business Week </li></ul> <ul><li>RCR Wireless News </li></ul> <ul><li>Radiation Research </li></ul> <ul><li>Pharmaceutical Representative </li></ul> <ul><li>New Hampshire Business Review </li></ul> <ul><li>Total Health </li></ul> <ul><li>Science </li></ul> <ul><li>FDA Consumer </li></ul> <ul><li>New York Times </li></ul>
