Running up and down ladders two weeks ago, then confused, incontinent, shuffling, and become glued to the floor in the space of a few days. CT scan showed glioblastoma, butterfly, on the corpus callosum. Not operable. Consultant recommended not to have a biopsy. 6 sessions of radiotherapy are booked in. Steroids have reversed the symptoms outlined above. Nobody wanted to ask 'how long', or 'what next', and there seems to be very little written which will help me mentally prepare for what will happen. I've read that the median time is 14 months from diagnosis, but surely diagnosis for some is early on, and for others, late on? Does anyone have any experience of this please?
