Maybe you can do both - go to your appointment and also go to Portugal by requesting any biopsy is postponed. At least then you stay in the hospital system and doctors can have an initial look at things within referral guidelines.  Just be aware you now have to quarantine coming back from Portugal in terms of booking any follow-up treatment/appointments.  

Hope you are able to have a lovely holiday. xx

Hi Jilly

I had the same problem last year i went had the biopsys no big deal new the sysyem and was aware results were available in about 2 weeks was so glad i went on my holiday enjoyed myself thourly came back was told it was cancer ( already knew ) and was in for a mastectomy 3 weeks later. My only issue is the quarentine of course they can telephone results but i presonally would not have wanted to wait the sooner your biopsys are done the better do not cancel your appointment then if still available go on the holiday best of luck
