My sister got the talk yesterday I’m crushed

my sister was diagnosed 2016 Mets to bone. last fall it was discovered in her liver. Her last treatment was a trial ibrance2 she didn't handle it well. Her platelets are low and they don't feel like she can undergo any additional treatments because of the progression in liver yesterday we got the news they are moving to keeping her comfortable I just read about microwave ablation is this anything that can help or is she too far gone. I’ll ask doctor toda
