Insurance for British living abroad

It is usual for travel insurance to be taken out from the country of residency. There’s an assumption that in the event of air ambulance service or repatriation that would be to your country of residency. Many also have a requirement that you’re registered with a GP (presumably in your home location). 

Your best options might be either a cancer support group in Cyprus or a specialist insurance broker again in Cyprus. Possibly try Facebook for local groups. 

Good luck
