Parents in California are requesting that a cell tower located on the campus of their children’s elementary school be removed. This comes after four students and two teachers were diagnosed with brain cancer in just three years, although the tower has been there longer than that. Some students at the school have already left as a result of the spike in cancer cases and recently, 200 parents attended a school board meeting demanding action. It’s a kindergarten through eighth-grade school that has approximately 400 students.
