It can be done differently but I always saw my oncologist on the day I had my chemo. If this is the case for your Mum, then you would be able to accompany her to this appointment, if she would like this. That would be the best way of finding out more about your Mum's situation.
It can be very hard facing any diagnosis of cancer, and there is so much new and foreign information to try and understand. It can be very overwhelming and you just have to take it one step at a time. That maybe how your Mum is feeling at this stage. Emotional support is the most important part of this process and that can be done even at a distance. Physical distance makes it hard but you can still be a great support for your Mum. Just understand that she will need to feel her way with this.
No one knows how to deal with this at first. Wishing you and your Mum all the best. Deanne xxx
