The idea behind the Optune is to disrupt mitosis with electric fields.
The person I’m referring to has survived, but has pretty significant cognitive issues(speech and reading disruption, memory gaps).
Unfortunately, that can happen. Often you have to cut through good brain tissue to get to the tumors. That’s never without a negative affect somewhere. Add in the cancer itself, the radiation and chemo take its toll too.
My tagline is a quote from a series of books called The Chronicles of Thomas Covenant the Unbeliever. It’s a Lord of the Rings type series. Thomas Covenant goes into a parallel world where his white gold ring has special powers. A few books later he goes back into the parallel world and gets his power back but they are broken. That’s how I see glioblastoma. If you survive the treatments, you don’t comeback the same.
