What Cell Phone-Cancer Study Means [ABC NEWS: 5-31-2011]
A World Health Organization panel of 31 scientists raised some concerns Tuesday when they reported that cell phones are “possibly carcinogenic” and may be associated with “some risk” for brain cancer. But the group also called for further study. Jeffery Brown discusses concerns and precautions with neurosurgeon Keith Black.

These three malignant properties of cancers differentiate them from benign tumors, which do not invade or metastasize. Researchers divide the causes of cancer into two groups: those with an environmental cause and those with a hereditary genetic cause. Cancer is primarily an environmental disease, though genetics influence the risk of some cancers. Common environmental factors leading to cancer include: environmental pollutants, diet and obesity, tobacco, infections, radiation, and lack of physical activity. These environmental factors cause or enhance abnormalities in the genetic material of cells. Cell reproduction is an extremely complex process that is normally tightly regulated by several classes of genes, including oncogenes and tumor suppressor genes. Hereditary or acquired abnormalities in these regulatory genes can lead to the development of cancer. A small percentage of cancers, approximately five to ten percent, are entirely hereditary. The presence of cancer can be suspected on …
Report discusses cell phone/cancer link
Can using a cell phone cause cancer? Studies over several years have had conflicting results, and now, a new review by the World Health Organization may be even more confusing.

By contrast, a cordless telephone is used only within the range of a single, private base station, for example within a home or an office. A mobile phone can make and receive telephone calls to and from the public telephone network which includes other mobiles and fixed-line phones across the world. It does this by connecting to a cellular network provided by a mobile network operator. In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, e-mail, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these more general computing capabilities are referred to as smartphones. The first handheld mobile phone was demonstrated by Dr. Martin Cooper of Motorola in 1973, using a handset weighing 2 kg. In 1983, the DynaTAC 8000x was the first to be commercially available. In the twenty years from 1990 to 2010, worldwide mobile phone subscriptions grew from 12. 4 million to over 4. 6 billion, penetrating the developing economies and reaching …
