My best friend was recently diagnosed with Glioblastoma.

In August of this year, Harry was diagnosed with Glioblastoma after we thought he was having a stroke. They were able to remove 90% of his tumor. He is currently undergoing radiation and chemo. Harry will celebrate his 74th Birthday this month. He has recently been having a lot of belching and hiccups. Has anyone come across anything to help stop or lower such symptoms?
