This is a very difficult question. It is quite natural that you will be concerned about your pregnancy and the fact that you have ruptured PIP implants. As you will be aware, the silicone used in the majority of PIP implants was a non medical grade silicone. To date, there have been no tests or studies that have shown that the silicone used in PIP breast implants is detrimental to health. Two studies in humans have found no increased risk of birth defects in children born to mothers who have had breast implant surgery (these studies looked at silicone implants in general - Not PIP implants).
Silicon is widely present in the environment and avoiding ingestion is difficult. Silicone drops have been used for years in Europe and the USA for colic.
Is the silicone within implants (including PIP implants) safe?
The American Regulator, the FDA, after conducting extensive studies and trials, reintroduced silicone gel implants in 2006 after a temporary ban that lasted 15 years. The UK Regulator (MHRA) commissioned toxicity testing on the unapproved silicone gel used to fill PIP implants including genotoxicity (the ability to damage DNA within cells) and chemical toxicity. The results of these tests have been discussed with relevant experts and the conclusion is that there are no safety issues relating to this filler material. The French Regulator confirmed these conclusions.
The MHRA consulted with experts to discuss whether there was any danger to ladies who breast fed with these implants. It was concluded that there were no safety issues.
Having said all of this, no one can know for certain that there will be no harm to your baby but it is highly unlikely. You have to weigh up the risks of having a general anaesthetic (including the risk to your baby of an anaesthetic) and the risk of leaving the implants in. Anaesthesia during pregnancy is safest in the third trimester of pregnancy. If your implants were not ruptured, I would have had no hesitation is recommending that you wait until after your pregnancy to have them removed/ replaced. Ultimately, you will have to make the decision with your prospective surgeon and anaesthetist.
