Hi Pooter,
There was another thread on this topic a while back, with mixed opinoions, you should be able to find it with SEARCH.
I have to agree with the other posts above, I wouldn't mention it. In the resume and interview process sometimes people are looking for a reason to exclude people to narrow down a list of applicants. This is normally a competitive process, and I wouldn't give them any reason to exclude me if I can do the job. Think of it from the perspective of other situations. If you where a single mother, would you mention that you have three kids. If your where older than the average person in this tyoe of position, would you mention your age? Bringing these things up, which really don't have anything with whether you can do the job well, could potentially be used to exclude a person for further consideration by a less than enlightened interviewer.
If you qualify for the job, and do not need special accomodations to do the job, then there would be no reason to bring up your medical history. If there was some special accomodation that you needed, that would be a surprise to the employer after hiring you, then perhaps that should come out earlier.
Good luck in your interview. Go in there with piratude!
Regards,
Rob
