I'm surprised that you haven't been given an indication of what type of BC you have but maybe it's not clear or that the clinic didn't organise your GP appointment. However, that's what you need to do now - get to the GP for a referral to a surgeon. Ask who he/ she would go to or who they'd refer their mother/ sister to. Whereabouts are you? You are likely to find recommendations from people on this site if that interests you. And whether you have private health cover will impact on your choice.
