Hi @DomThom I really feel for you. For me this was the most stressful part in many ways. Like you I had all my tests at once, then had to wait a few days for the outcome.
All I can advise is what worked (mostly) for me, which is to try to cross each bridge as you come to it. Should your lump turn out to be a cancer you can then turn to resources such as breast care nurses who can advise and help you find other resources.
Once you know what you're dealing with, you'll then find out what treatment is required and be able to decide whether it will be necessary to be in the city to access that treatment. Even if it is a cancer, you may only need minimal treatment. Not everyone needs chemotherapy, for instance.
I discovered a great podcast yesterday that you might find useful - The Thing About Cancer.
