I would be very sceptical of what she has told you.
My son (27) was diagnosed with a Glioblastoma (GMB4) in June 2022 after 1 seizure - with a prognosis of 12-15 months. Unfortunately this is given as a median because everyone is different.
After having an awake craniotomy, he went through 5 days a week for 6 weeks radiotherapy. He did lose his hair but only at the side where the radiation was carried out. He had a huge scar running from his temple down to his ear and then round.
He had a month off after the radiotherapy and then started 6 months of chemo - usually this is in tablet form taken at home.
Went back to work part time - October 22.
He had two years of stable scans - could not take all of the tumour due to it's placement - he would have lost motor skills/speech.
April 24 had a further craniotomy due to more growth, chemo given but it didn't work. Different chemo given - IV this time which has helped stabilise. However there was only a 50% chance of this reducing/stabilising and there are no other options after this.
He is exhausted all the time. I know he is declining.
GMB4 is terminal - her MacMillan team would have sorted out a blue badge and PIP for her - does she have these?
It takes two years of stable scans to maybe get your driving license back - you have to surrender on diagnosis, and then there is a lengthy wait whilst the oncologist fills out forms for the DVLA etc.
