Causes Of Brain Cancer
Study Suggests Cell Phone Use Not Associated With Brain Cancer - Brief Article - Statistical Data Included Talking on cell phones isn't linked to an increased risk of brain cancer, suggests a recent study supported by Wireless Technology Research and the National Cancer Institute.
Researchers interviewed 469 men and women aged 18 to 80 with brain cancer and 422 matched controls without brain cancer between 1994 and 1998. Researchers asked subjects if they had ever subscribed to a cell phone service, and they gathered such information as the number of years of use, the amount of time used per month, and the year of first use.
The median number of hours per month of cell phone use was 2.5 for the cancer patients and 2.2 for those without cancer. The mean duration of use was 2.8 years for cancer patients and 2.7 years for those without cancer. The differences between the cancer patients and those without the disease were not statistically significant. Researchers concluded there was no association with brain cancer according to duration of use, but also stated that more studies on long-term use of cell phones are needed.
