Hi. I have a single bone met and went to the USA in October 2017. We looked high and low for insurance, but only All Clear covered metastatic BC. The cost was ridiculous, so we took our "normal" travel insurance with RACV (for our luggage, flights, etc) and decided that if anything happened to do with my cancer, we would jump on a flight and return home. We also didn't finalise any of the accommodation until a few weeks before (through Booking.com you can cancel up to the day before for many hotels, but check the fine print). We are planning a trip to Italy in May... will follow the same formula. It's hard to make these decisions. All the best! Amanda
