Investigating the use of a common vitamin to treat the aggressive brain cancer glioblastoma

Edward (Ed) Waldner had no idea why he didn't feel well, but he knew he didn't feel like himself. At 55 years of age, he felt exhausted all the time.

One day, when his symptoms were worse than usual, he decided to go to the Emergency Department.
