Is detecting BC classified as a pre-existing condition?

Frustration over paperwork!  My GP completed the form today, but her receptionist would not email it as it 'contravenes their privacy policy'. So now it is in the post.  I doubt I'll see it until the end of the week (after the operation).  The specialist had no problem emailing his back.  All it means is I have to pay the excess up front, and I'll get it back if the paperwork goes through.  Not like I'm going to be out at the shops spending any money after the operation anyway!
