Hold the Phone!


1)  This is the longest study to date on the malignant brain tumor risk from using wireless phones, both cell phones and cordless home phones.
2)  This is not the first epidemiological study to find a significant association between the use of cellular telephones and brain tumors.
3)  The risk of malignant brain tumors (primarily high-grade astrocytomas) increases with the longer the use of wireless phones.
4)  The risk for all malignant brain tumors increased rather dramatically for those who used combinations of a cell phone and a walk-around cordless phone.
5)  Analog cell phone use for more than 15 years increased the risk of malignant brain tumor to 510% with a range between 150% to 1,400%.
6)  The incidence of malignant brain tumors found in this study is low because those that died of malignant brain tumors were not counted.  They were only counted if they were still living.
7)  For a variety of reasons, the microwave radiation dose was higher for cordless home phone users than for digital cellular phone users, making these devices even more dangerous.
