Yep, I too would be questioning the GP and his lack of bedside manner !
How dare he suggest that she "get her affairs in order" ?? !!
That is simply unprofessional and highly insensitive.
I would be asking for an appointment with this GP - if he is the family GP and had previously had a good relationship - and go with a support person only AFTER she has seen her surgeon armed with facts.
Thank goodness she has good support from people like you.
Please let her know about this site - it may also help to alleviate some of her fears and answer a few questions.
