Hello -  any advise would be much appreciated

our beautiful 84 year old mum had been complaining of a fuzzy head and was  a bit depressed but we thought it was due to lockdown

she had a fall in January 2022, we took her straight to A&E, after 6 hours we were released at midnight with bad bruising

the, what we thought was depression, continued so we insisted on seeing the docter presuming possible dementia - 2 cancelled appointments and following my tears to the receptionist we managed to see her docter - who referred her to the memory clinic

3 days later what seemed stroke symptoms we were rushed into hospital, admitted and found out mum had stage 4 lung, spread to brain, bone and lymph nodes

mum was released, with steroids - we returned for a biopsy and at the follow up at hospital last week we were told no treatment wd be recommended

we are obviously devastated and in shock - mum is not in pain, she has lost weight, but eating well now, admittedly she is frail and a little confused now - but is there anything else we should be doing?  Please help we are desperate - do we try for a second opinion??
