Magnetic helmet shrinks tumour in 53-yr-old man's brain by a third

Researchers in US used a helmet that generates a magnetic field to shrink a deadly tumour in a 53-year-old man's brain. The patient ultimately died from an unrelated injury, but an autopsy of his brain confirmed rapid response to the treatment. The test marked world's first noninvasive therapy for the deadliest of brain cancers known as glioblastoma, the researchers said.
