Cell phones do not cause brain tumors, Danish study says

• A new Denmark study published Tuesday found no correlation between cell phone use and the development of brain tumors.
• A study published Tuesday in a medical journal found no connection between the use of cell phones and increased risk of brain tumors.
• The study, conducted in Denmark, was published Tuesday by the American Academy of Neurology.
• The study interviewed 427 people with brain tumors and 822 without tumors, asking about their use of cell phones.
• The study found no correlation between the development of brain tumors and how frequently mobile phones were used or how many years they were used for.
• Nor did the study find any evidence that brain tumors were more likely to occur on the side of the head most used with cell phones.
• The findings are consistent with other studies, Dr. Christoffer Johansen of the Danish Cancer Society, said in a statement.
• Johansen was one of the study's authors.
• "These results are in line with other large studies on this question, including a recently published large-scale, population-based study by the Swedish Interphone Study Group," Johansen said.
• "There have been a few studies that found an increased risk of brain tumors with cell phone use, but those studies have been criticized for problems with the study design."
• A 2002 study, for instance, found some indication that long-time users of analog cell phones had a greater tendency to develop a specific type of tumor on the side of the head most often used for making calls.
• Johansen cautioned that the new study covered very few people who regularly used cell phones for more than 10 years.
• "In our study, few people reported regular cell phone use for 10 years or more," Johansen said.
