Cell Phones and Cancer Risk
 

An eighteen year study comprised of 350K Danish cell phone users has reached a conclusion that cell phones hold no greater risk of contributing to the incidences of cancer than a non-cell phone user would face. There is no evidence that using mobile phones—even very heavily—has any correlation to developing brain or nervous system cancer. So, in all probability, you can use your phone(s) any way you like and be just fine.
