PEMBROKE PINES, Fla. -
The city of Pembroke Pines wants its residents to know that cell phones could be dangerous and linked to cancer. A newly-passed resolution was inspired by a resident who believes his brain tumor was caused by his mobile device. Pines resident Jimmy Gonzalez had tumors removed in his brain above his left ear, his left hand, and near his hip. All places where he said his phone was pressed for long periods of time.
