Summarise a Medical Letter Before a GP Appointment

A letter arrives from the hospital, full of clinical phrasing, and your appointment is Tuesday. Paste it and it translates plainly: what the letter is about, what you're being asked to do and by when, any results mentioned. It does not diagnose or advise on treatment, it just gets you in the room prepared.
