Speaking to your insurers is probably best, you don't want something to happen and find you aren't covered.
In my experience with a bank account linked travel insurance (Nationwide for us) while there is something still under investigation they simply say a claim related to the investigation (i.e. anything to do with the prostate) is excluded but other things remain covered. The results so far don't suggest any related medical emergency is likely in the next few months, but you will want to know you are covered if (say) a broken leg means you need to pay for hospital treatment and to rearrange your journey home.
