Advice please

So my mil had a ct scan on Monday due to various health issues and on Tuesday ended up in a&e has she is unable to keep anything down it was there the doctor told us there was a mass on her left Lung and also a lump the size of a golfball under her armpit she is 72 for reference she was admitted to hospital and has had a biopsy taken from the lump under her armpit she is still unable to eat or swallow so has had an ng tube in she has since had another mri and we have been told there’s cancer in the liver and mets on the skull but not the brain I know I can’t get a definite answer has everyone’s different but is she likely to be offered any treatments ? It’s obviously advanced she’s such a lovely woman who will fight until the end she has been put on a syringe driver today and been given Midazolam has she’s having involuntary arm and leg movements it seems like such a long time for biopsy results to come back.
