Cell Phones

In recent years, the number of cell phone users in Canada has grown dramatically and there are five billion users worldwide.

Some research suggests a possible link between the use of cell phones and brain tumours but much more research is needed.

The World Health Organization (WHO) (May 2011) and Health Canada (October 2011) ** offer precautions for cell phone users who are concerned:

  • Parents should limit their children's use of cell phones
  • Reduce exposure to radio-frequency energy by limiting the number and length of cellphone calls
  • Using a mobile phone 30-40cm away from their body - for example by substituting text messages or chats in the place of phone-to-ear cellphone calls
  • Using a hands free device
  • Using the phone in areas of good reception also decreases exposure as it allows the phone to transmit at reduced power
  • Parents should limit their children's use of cell phones.

How to limit wireless exposure

Here are some tips for reducing exposure to electromagnetic radio-frequency waves, based on the precautionary principle:

  • Turn off cellphones or tablets when not needed, or turn on airline mode
  • Keep cellphones away from your head as much as possible. Use speakerphone mode or earbuds for phone calls rather than a Bluetooth headset. Don’t carry your phone in your pocket or bra
  • Do not sleep with wireless devices near you
  • Keep cellphones and tablets away from small children
  • Use a wired baby monitor instead of a wireless unit. Do not place a wireless baby monitor by your child’s bed. Use a wired monitor instead
  • Use hardwired Internet connections for computers in your home instead of using WiFi. Turn wireless router off at night; do not keep it in high-use or sleeping areas
  • Pregnant women should keep wireless devices away from the abdomen
  • Avoid cordless phones.

This reality does not stop Stephanie from her tireless efforts to reduce the stigma of having a brain tumour. Learn why Stephanie is urging all Canadians to make every brain tumour count.
