New research shows PIP breast implants won't cause cancer, but they're up to six times more likely to rupture than other brands.
The French-made PIP implants have been at the centre of a worldwide health scare after it was found they were filled with silicone designed for use in mattresses.
About 5000 Australian women were fitted with the PIP breast implants between 2000 and April 2010.
A group of UK experts have been examining the safety of the PIP implants and say despite the fact they won't cause cancer, it is best if women get them removed.
PIP implants are between two and six times more likely to break or perish than other brands. According to the Australian Therapeutic Goods Administration, "localised inflammation causing lumps and/or discomfort may occur typically with extra capsular rupture".
"This has been an incredibly worrying time for women," said study leader Professor Sir Bruce Keogh, the medical director of the UK National Health Service.
"We have been determined to look thoroughly at all available evidence so we are able to give them the best clinical advice possible."
Tests were carried out in the UK, France and Australia.
"Those tests have shown that the implants are not toxic and therefore we do not believe they are a threat to the long-term health of women who have PIP implants," Dr Keogh said.
"I sincerely hope this helps to reassure women that their long-term health is not at risk."
Official acknowledgement of the flawed implants opens the opportunity for women to sue.
The Australian Therapeutic Goods Administration suggests women who have had PIP implants make an appointment with their surgeon for a clinical evaluation.
