Hi there- this happened to me. I was recalled & given an appointment date when I was due to be on holiday.  I knew I could never enjoy the holiday with the uncertainty of the recall hanging over me so I rang numerous times every day in the hope of getting a cancellation & finally I got one.  Thankfully, my recall was due to a ‘spot’ on my right breast that wasn’t there on the mammogram 3 years before so it was flagged as a ‘change’ & prompted the recall.  It’s worth knowing that the majority of recalls don’t result in a cancer diagnosis (as mine didn’t) as the sensitive equipment can detect the slightest change.  The ‘not knowing’ is the worst bit so if you are able to somehow get an appointment before your holiday I would encourage you to try to do that.  My outcome allowed me to go away with complete peace of mind that all was ok & it was so worth those phone calls that got me the cancellation.  I wish you well & hope that your recall outcome is in line with the majority & is nothing to worry about.  Take care x
