@Michelle B I would have the scan for peace of mind. You’ll enjoy your trip when you get the all clear. Worst case scenario, you have got onto it early and can deal with it. I had a spot on one of my scans and had a whole body scan earlier this year. It was stressful, but once I booked in I could hand it over to the doctors to find out. I got the all clear and I hope you get good news back too. I’ve had 3 whole body scans in total. Remember to keep your eyes closed during the scan and visualise a place you love to be. This will help.
I know exactly how you feel. Your family is probably more stressed by the what if’s and your well-being than any holidays or scans. x
