Long term use Mobile Phone and Brain Tumor Risk

This informative presentation explores the potential risks of long-term mobile phone usage on brain tumor development. Presented with comprehensive research and case studies, it sheds light on the health hazards associated with cell phone radiation and offers practical proposals for minimizing risks. With a focus on ionizing and non-ionizing radiation effects, the session concludes with helpful tips and references for mobile phone users to safeguard their well-being.

  1. Long term use Mobile Phone and Brain Tumor Risk Presented to Prof. Dr. Eduard Heindl By SwapnaNelli

  2. Agenda • Introduction • Radiation cause Brain Tumors • Case control study in Sweden • Health Hazard linked to Cell phone use • Helpful proposal to Mobile phone users • Conclusion

  3. Introduction • Population of the world 7.018 billion • Mobile phone users 4.6 billion • Advantages • Is there any health risk of using mobile phones?

  4. Radiation cause Brain Tumors Ionizing Radiation • Exposures are from X-rays, A-bombs, radioactivity • Only “known” environmental cause of brain tumors (since 1974 or earlier) • Energy sufficient to break molecular bonds • For example, DNA • Broken DNA creates free radicals • Free radicals cause further DNA damage thought to cause cancer

  5. Radiation cause Brain Tumors Ionizing Radiation • Increased risk of brain tumors • Age: Children at greater risk than adults • Risk increases with power (Watts) • Risk increases with time • Excess risk, 30 or more years (all ages) • Brain Cancer: double • Meningioma: 70% • Latency time (from exposure to diagnosis) • Brain Cancer: 20 to 30 years • Meningioma: 30-40 years

  6. Radiation cause Brain Tumors • Exposures from cellphones, cordless phones, walkie-talkies, baby monitors • Risk of brain tumors • Energy cannot break molecular bonds • Creates free radicals; increases lifetime of free radicals Non-ionizing Radiation: Wireless Phones

  7. Radiation cause Brain Tumors Non-ionizing Radiation: Wireless Phones • Increased risk of brain tumors • Age: Younger have higher risk • Greater than 5 years of cell phone use • 70+% for 20-29 years olds (7 cases, 94.8% confidence) • 35% for all ages, 20-80 years (160 cases, 97% confidence) • Risk increases with power (Watts) • Risk increases with time • Tumor on same side of head as where digital cell phone was used • 26+% increased risk of brain cancer (97 cases, 99.91% confidence) • Latency time • Much shorter latency time than ionizing radiation

  8. Case control study in Sweden • Introduction • Late 1980’s • Stefan Lönn, Anders Ahlbom, Per Hall, Maria Feychting and the Swedish Interphone Study Group • Materials and Methods • Case ascertainment • Control selection • Data collection • Classification of exposure • Statistical analysis

  9. Case control study in Sweden

  10. Case control study in Sweden Outcome of case-control study • The odds ratio was 0.8 (95% confidence interval: 0.6, 1.0) for Glioma and 0.7 (95% confidence interval: 0.5, 0.9) for Meningioma. • No studies to date have had an exposure time long enough to properly address the potential adverse late health effects of mobile phone use. • Tumor depends on not only the duration of call as well the type of phone, age of the person gendor of the person and place also

  11. Health Hazard linked to Cell phone use • Harm your blood cells • Damage your DNA • Cause nerve-cell damage • Possibly accelerate and contribute to onset of autism, and trigger Alzheimer’s disease • Damage your eyes • Cause sleep disruptions, fatigue and headaches • Contribute to salivary gland tumors • Cause decreased bone density in the pelvic region • Lead to electromagnetic hypersensitivity • Affect your heart rate and blood pressure

  12. Helpful proposal to Mobile phone users • Limit the use of cell phones • Children should not be allowed to use a cell phone • Do not put the cell phone in a pocket or a belt • Do not use the cell phone in enclosed metal spaces • Do not make a call when the signal strength is weak • Do not use the cell phone when battery is low • Purchase a phone with a low SAR • Use text instead of talk • Use landlines • Keep cell phone off most of the time
