Hi and welcome to the online community
Unfortunately, as you have found, it can be more difficult to find travel insurance when you either have cancer or have had it before.
Have you had a chance to look through the Recommended Travel Insurance thread that Mitzie10 mentioned yet as it's where we try to keep recommendations from other forum members who have obtained travel insurance? There may be a company listed that you haven't tried. Either scroll down the page to it or click on the link I've created.
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 complete an online form.
I do hope that you can get travel insurance and have a great time in America.
