Travel insurance "computer says no"

Trying to get travel insurance for myself & Mrs dB for a two week trip - stumbling block is that she recently had a camera investigation, nothing found & no concerns but they routinely take a biopsy, results of which we won't get until after we leave or even before we get back... But trying to get insurance when you declare "awaiting results" is proving difficult even with specialist medical insurance & I don't want to give them an excuses should the worst happen.

Basically just need to find an insurer who I can talk to & get some sensible decision, anyone any suggestions?
