Thank you for your replies. Went to the Doctors with Mum today and after taking all your advice asked loads of questions and now feel slightly better and optimistic about the future. She starts Chemo by tablet soon which has put her mind at rest as she thought she would have to stay in hospital meaning she would have been apart from my Dad who is disabled. She has been his sole carer for many years now and though obviously now they will need outside help it makes us all happier that they will be together through this first stage of treatment.
