Hi, my dad got diagnosed with gbm 4 last sat after a week of confusion, it is unoperable.He is having 8-15 days of radiotherapy to try and control the tumour. While i was with him to get the diagnosis they asked dad if he wanted to know how long he had or what to expect but he said no, however my sisters and i would like to know as we are going to be caring for him and are all single parents,i have 3 children, the youngest being 3 months. My sisters both have babies too. My dad is adamant he doesn't want hospice care. Does anyone have any experiences with this cancer, and also does anyone have any idea as to what to expect? TIA.
