Beau Biden's Brain Cancer Death: Part of an Epidemic Fostered by Mobile Phones?

This weekend news of the death of Beau Biden, the son of current U.S. Vice President Joseph Biden, has brought attention to the increasing incidence of brain cancers among the population. Beau Biden was a rising star in Delaware politics, expected to run a successful campaign in 2016 for Governor of the state. However, he was diagnosed in 2013 with a brain tumor and went through treatments that included surgery, radiation, and chemotherapy. The cancer appeared to have gone away following the treatments in 2013, however it was found to recur this year in 2015 and Biden returned for aggressive treatments. Many cancer researchers have pointed out that radiation and chemotherapy are associated with a high risk for future malignancies and more aggressive forms of cancer. Biden received these conventional cancer treatments, and the return of the cancer in an aggressive form is not surprising.
