Hi all

I am hoping someone will have some advice. My 70 year old mum with recently diagnosed dementia was diagnosed in october with grade 2 her positive duct cancer. She had a mastectomy on Wednesday but seema to be incredibly tired today drifting in and out of sleep and a little unsteady on her feet. She is not a great eater and only weighs 7 stone 10. I am worried as yesterday she seemed alot better. washed dressed and awake all day. Is this normal. I'm terribly worried 

Thnk you in advance
