Iron Maiden frontman Bruce Dickinson won his fight against stage three throat cancer, marking ten years since his 2014 diagnosis. Doctors found a tumor as big as a golf ball at the base of his tongue. That means that the tumor was judged to be a stage three tumor," Dickinson revealed in an interview. He went through 33 rounds of radiation and nine weeks of chemo. The medical team gave him two gray units of radiation each day for six weeks, targeting his head and neck.
