Hi May
And a warm welcome to the group. Sorry to hear about your Mum.
Its a worry when the treatment fails But there is a lot out their that will work its trying to find out what and when it will work. I tell Elaine (my young bride) when its time to sort things out the Dr will tell us just let them sort out all hiccups as we travel the road to remission.
Its great to read your Mum is positive as am sure that helps along the way.
Good Luck to your Mum on the road to remission.
