Cell phones not linked to eye melanoma

Cell phone use is not associated with the risk of melanoma of the eye, researchers in Germany said.

Dr. Andreas Stang of the Martin-Luther-University of Halle-Wittenberg in Germany and colleagues examined the association between cell phone use and risk of uveal melanoma -- melanoma of the eye -- in 459 patients and 1,194 control subjects.

Control subjects were drawn from the general population, from ophthalmology clinics and from siblings of the patients. The investigators grouped study participants according to amount of time spent on the phone, as never users, sporadic users and regular users.

The study, published in the Journal of the National Cancer Institute, said there was no statistically significant association between cell phone use of up to about 10 years and uveal melanoma risk.

In conclusion, we observed no overall increased risk of uveal melanoma among regular cell phone users or users of radio sets in Germany, where digital cell phone technology was introduced in the early 1990s, the study authors said in a statement.
