The U.S. Brain Tumor Association has warned in news releases about what it says are the dangers of cellphones. It has not filed the federal tax form and it lists a Gmail address as contact information on its website. A spokeswoman for the American Brain Tumor Association (ABTA), which was founded in 1973 and funds more than $1 million in research annually, said “not one single person” among ABTA experts was familiar with the group. The group lists Kevin Mottus as its president and only staff.
