"Bad communication"

I recently went for a transvaginal ultrasound. Letter arrived from a consultant informing me I would need a biopsy. A letter arrived one month later with a date and time to see a gynaecologist but no reference as to what was going to be done at this appointment.

After deliberating for a few days I rang the gynecologist's secretary to ask the question of what was my appointment for.  I was told it was my biopsy appointment. Nowhere on the letter did it state that it was for a biopsy. No leaflet to tell me what is involved, what pain relief I should take, how I should dress, how long it will take, etc.  

For patients comfort and sanity it would be nice to be told in advance what is happening and would stop most of the unwanted phone calls to the secretary who probably has enough to do without having to answer questions that should have been made clear in a simple leaflet or on the appointment letter.
