Do smartphones cause cancer?

In my first novel, The Empty Spaces, available on Kindle and the best way to support this site and my work here...

Wake up!

Seriously. In my book one of the storylines involves the potential for smartphones to cause cancer. The verdict:

It's a work of fiction so I sent that storyline in a completely different direction (instead, smartphones may kill our desire for chocolate and marijuana). But, being the person of ethics that you know me to be, I did not incorporate any false or misleading data into the cancer debate and I had one of the characters reviewing the information state quite clearly that the muddled view we have on this topic. Essentially: well, it probably doesn't matter because we've all decided to have and use our smartphones, cancer be damned. 

The famed Dr Mercola, says otherwise. He believes that major studies reviewing smartphones and cancer are (possibly deliberately) flawed and that smartphones do indeed cause cancer. Especially for heavy users such as business persons:

A new BMJ study being widely circulated in the media claims to have found no association between long-term use of cell phones and brain or central nervous system tumors, but the study was deeply flawed and misleading

The BMJ study excluded the heaviest cell phone users -- more than 300,000 business users, which represented nearly 30 percent of the original group – which skews the results significantly

A cell phone “user,” as defined by the study, was anyone who made one call a week for 6 months, which again does not reflect the true risk of heavy cell phone use that is commonplace today

Cell phone studies are commonly spun by industry to support cell phone safety, when in fact closer analysis reveals increased cancer and other health risks

The science is very clear, and many worldwide health agencies, now concur, that the cancer risk from cell phones is real, and steps should be taken immediately to minimize your risk.
