A 51-year old fitness instructor in Wales had her fake breast explode.

Brockhurst said that while the NHS was willing to take out the faulty implants, she would have had to pay an additional £3,800, a fee that she was not able to afford. She finally underwent a corrective surgery and reduced her breast size to a manageable 34D, with the costs of the surgery borne by Channel 5 reality TV show Botched Up Bodies.
“I was really flat chested and I wanted a bit more bounce. So I saved up for the surgery hoping it would give me a nice confidence boost. But I ended up with these big heavy breasts - much bigger than I'd asked for. But it got worse when my breasts slowly went out of shape - it was a terrible time. Soon I had a big dent in my right breast and the implant on the left just exploded - leaking the implant's industrial strength silicone into my breast tissue”, Brockhurst said.
