Thanks to everyone who replied to my first post on this. My husband and I stayed over in Southampton and we got home today.
To my great relief, the consultant was extremely approachable and excellent at explaining things. I didn't ask all of my questions as these initial discussions are being done over two appointments. It's good not to feel rushed. He gave me a very thick book about the whole procedure and I will also have a copy of the letter he sends to my regular haematologist.
I came away well aware that this is a huge and risky process, but having met this consultant and the main SCT nurse, I feel I would be in safe hands.
If a donor can be found, I am inclined to follow advice and choose to have it. I have another telephone appointment with Prof Harrison before my next Southampton appointment, so there's time and opportunity for further discussion.
There are some logistical issues with twice weekly follow up appointments, each of which would be a 140 mile round trip. Luckily my husband, although ten years older than me, is fit and willing to drive, but it would be demanding for both of us.
Again, thank you all for your thoughts and sharing your experience and ideas, Jennie
