UK cosmetic surgery has a graveyard of household names — chains that placed tens of thousands of implants, then collapsed, taking records into administration with them. If you can't find out what's inside you, you're in numerous company — and better off than you fear.
Photos over the years (your camera roll is a clinical timeline), the rough date and clinic name, any GP correspondence, and your own memory of size and problems since. That's a workable file. The one document worth one email attempt: administrators of collapsed chains sometimes hold transferred records — a request costs nothing.
Revision surgeons operate on findings, not paperwork. Assessment, imaging and intra-operative judgement replace the folder your old clinic lost. Missing records delay nothing here except, occasionally, your own permission to start — consider it granted.
