Have you looked at the list on the Macmillan website? Lots of suggestions there. I obtained annual insurance from Staysure for me and my partner to cover trips to Mallorca
I'm incurable but treatable with prostate cancer and got worldwide annual cover with Holidaysafe via comparison site albert&eddie. They are part of the same group as Holidaysafe and Insurancewith and I found they were worth a try.
