I've spoken to my Mum in the last half an hour - she's now home from hospital. The good news is that they got all of the tumour out and that it was a grade 2 (therefore benign). She will have to have follow up scans to ensure no cells got left behind and are growing again, but the prognosis is generally good. Now we just have the long process of healing and recovery. I will be going down to Gloucestershire on Thursday after work to spend the weekend with my Mum (and my Dad and brother).
