Let me begin this blog with “I do not know” whether cell phone used causes brain cancer in the form of tumors or not. However, not knowing something means you do not know and hence caution is most likely in order, particularly when cancer is the point of discussion.
Let me try to ease the confusion and suggest some lifestyle steps to avoid unnecessary risk if it is present. A primary malignant brain tumor is one in which the cancer originates in the brain itself rather than traveling to the brain from another region of the body (metastases). There are over 20,000 new cases of primary brain malignancies each year. A specific form of brain tumor known as the glioblastoma multiforme has increased 30 to 70 percent from one decade to the next in some metropolitan areas of the United States. It is believed that ten times the number of metastatic brain tumors will also occur in the same time period.
Risks for cancer include pesticides, air pollution, chemicals found in meats, power lines, and plastics. Xrays are also on the list of risk factors including the microwave type radiation emitted from cell phones. This is why cell phone companies suggest we hold the phones away from out ear when using it. Further, there have been several studies indicating a relationship (not cause and effect) between cell phone use and risk of brain cancer, increased risk of acoustic neuroma, and glioblastomas. It is important to note that other studies that have not found any relationship between cell phone use and increased risk for brain cancer. We will most likely learn more about this relationship as we have more time to study the use and effects of cell phone use on a larger number of people over a greater period of time.
As cell phone use is a lifestyle issue, what can be done at this point? There certainly has been an increase in the number of users and the amount of time each user spends on their cell phone. Some homes do not even have land lines anymore. Children are using cell phones at unprecedented rates as well. Dr. Black, renowned neurosurgeon suggests that parents try to curtail cell phone usage in their children. Even adults are encouraged to use an earpiece (not a blue tooth) to avoid direct contact between the phone and the ear.
I have started to use an earpiece myself.
