The Danish study included a group of 420,095 Danish cell phone users. The study examined the cancer rates of cell phone users that began cell phone use from 1982 to 1995 and follows their cancer rates through 2002. Denmark was an ideal place for this study because they keep a national cancer registry. This is a system that logs and tracks every person who is inflicted with the deadly disease.

In the study, cancer appeared in only 14,249 people in the research group, as apposed to 15,001 cases that appeared in the general population. According to an article in ars technical, “Cell phone users had no higher risk of brain tumors, acoustic neuromas, salivary gland tumors, eye tumors, or leukemias, though the study’s authors note that ongoing research is needed to make sure the results hold true for those who have used a cell phone for more than 10 years.”

This is by far the largest most comprehensive piece of evidence to combat the urban legend that cell phones cause cancer. Among the 56,000 cell phone users that were watched for more than a decade, the research concluded there is absolutely no increased risk of cancer due to cell phone use. Good news to the more than 219 million Americans that use cell phones regularly.
