Can electric cars cause cancer?
Hybrid and electric cars may be cancer-causing as they emit extremely low frequency (ELF) electromagnetic fields (EMF). Recent studies of the EMF emitted by these automobiles have claimed either that they pose a cancer risk for the vehicles’ occupants or that they are safe.
