@MrsMorrisey I am a needle / hospital phobic and therefore the idea of mapping scared me. I read a lot on bcna (tried to stay away from Dr Google) and spoke to a few people who'd had this done recently. Most importantly a friend came with me to the appointment.
The doctors and nurses at Mater imaging were wonderful. They settled me, joked with me, discussed everyday life and talked me through the whole process. It was fine.
For me, it was the fear of the unknown and the whole big package of BC.
You will be ok but if you can take a friend with you to hold your hand and just be there, that's the best advice I can give.
