New research shows that cellphone usage is associated with an increased risk of tumors.

Using 107 published articles out of an initial 425, researchers conducted a meta-analysis of case-control studies, and found “significant evidence linking cellular phone use to increased tumor risk, especially among cell phone users with cumulative cell phone use of 1,000 or more hours in their lifetime.”

The most common type of tumor was of the brain; head and neck cancers were second-most prevalent; and hematologic malignancies such as leukemia and non-Hodgkin lymphoma and testicular cancer were third- and fourth-most prevalent.

The authors commented, “Importantly, in the subgroup meta-analysis of all studies reporting cumulative call times greater than 1,000 hours, cellular phone use with cumulative call time greater than 1,000 hours (about 17 minutes per day over a 10-year period) increased the risk of tumors by 60%.”
