My mum has been diagnosed with a glioblastoma. She is almost 70 and the symptoms came on rapidly. The consultant said he does not recommend doing a biopsy due to the location of the tumour and doesn’t feel treatment would give her more than an additional 3 months beyond the 3-6 months he has given as life expectancy. Does this sound reasonable? I don’t want her to undergo pointless treatment that would diminish the quality of life she has left however if there are options that haven’t been offered we would want to consider them. At present she is being offered medication to mange the symptoms
