Travel insurance

Hi,i have just recovered from bowel cancer after 2 years of operations and chemo and have had my 6months all clear scan.I was looking to go away on a special holiday but travel insurance quotes are ridiculous.I read that some companies will do you a policy that excludes cancer related claims but will still cover you for other things like a broken limb etc.I was just wondering if anyone had any experience of this,any help would be greatly appreciated,many thanks
