Friend has an inoperable brain tumour. How do I support her?

She’s only just turned 31. She’s had two brain surgeries prior to this to remove tumours, was in remission for a year, and has recently found out more tumours have appeared. Unfortunately this time the doctors have said it’d be too dangerous to operate again to remove them as it could potentially leave her disabled. Her only option is to do nothing or have chemo which MAY slow the growth and give her a little more time. I have no idea what to say to her or how to support her. Fk Cancer.
