Hi Beserker and welcome, sorry to hear your husband has prostate cancer. As i don't know your prognosis or treatment i can't be specific. Iy as it seem you like holidays, you can get worldwide annual travel insurance with, INSURE AND GO or INSURANCE WITH, if you holiday in Europe only STAYSURE do a Europe only policy. A couple of tips if your husband is having radiotherapy, if you can wait until it is completed your premium will be much lower and if you can talk to someone instead of doing it online, 

Eddie
