Thirty patients are suing Barnsley hospital claiming that a consultant botched their breast surgery operations.

Surgery patients sue hospital
This is a BBC News webpage.

There is a video interview with one of the victims of the consultant's poor surgery. She has had to have repeated surgery and still requires reconstructive surgery. She has lost her job and is living on Incapacity Benefit.

That as many as thirty patients are involved in this inclines me to think that their complaints were not being taken seriously until the numbers became too big to continue to ignore.
