Hi and welcome to the travel insurance group
I'm sorry to hear that you're struggling to get travel insurance. Unfortunately, as you have found, it can be more difficult to find reasonably priced travel insurance when you have had a cancer diagnosis.
Have you had chance to look through the Recommended Travel Insurance thread yet as it's where we try to keep recommendations from other forum members who have obtained travel insurance? If not, clicking on the link I've created will take you to it and you might find some companies that you haven't tried yet.
Most people recommend that you phone the travel companies rather than try and do online quotes as it's easier to explain to someone than try to do it online.
I do hope that you can get travel insurance and that you have a great time visiting your son
