Hello my dad was diagnosed with a very aggressive grade 4 brain tumour. He had surgery to remove as much as possible at the end of December. The surgeon said that the outcome was a good outcome it could of been better but a lot was removed however because of where it is in the brain they were unable to remove the whole thing and that it is incurable and very likely to return. He is due to start both radio and chemo therapy next week but I am wondering from experience how long does it usually take for these things to regrow ? A few months a year ? If anyone could help I would be really appreciate as I feel like everywhere I've looked there isn't much info on this kind of thing.
