Hi @Pommy8, it is so overwhelming isn't. @arpie has given you great advice. I am sorry you are going through this. There is a bit to get through for sure.
For now try not to get too far of yourself. It is all scary at the start with appointments and lots of information. Keep busy. Breathe deeply and push out the over thinking and what if thoughts. Treatment is so good and so too is recovery.
You have everyone's support here and you can ask anything. I could not have got through my breast cancer diagnosis and treatment without this group.
Let us know how it goes with the specialist if you like. Best wishes
