Is biopolymers injection can be dangerous if im pregant?

Hi Kathou05, Thank you for your question regarding pregnancy and biopolymer injections.  Biopolymers are associated with painful granulomas and even cancers.  Usually, before biopolymers start to cause you problems, I suggest you have these biopolymers removed.  However, since you are pregant now, you cannot undergo surgery because of anesthesia risks to your child.  As far as I know, there have been no docuemntated cases of transmission of biopolymers across the placenta to your baby. So, I think your baby is safe, but no one really knows.  Also, the risks of doing anything now (surgery), outweigh the benefits of biopolymer removal.  I would suggest you have the biopolymers removed once you have stopped breast feeding. Since removing biopolymers is not an easy procedure, please seek an experienced, board certified plastic surgeon with significant experience in removing silicone.  Among other things, I specialize in silicone removal.  Do your research.  Make sure they have performed at least 100 breast silicone removal surgeries and have the before and after pictures to prove it.  Carefully examine their before and after pictures and check their reviews on RealSelf.   If you cannot find an experienced, silicone removal surgeon in your neighborhood, consider traveling out of state if you must. Sincerely, Dr. Katzen. (“Verified” Plastic Surgeon, Certified by the American Board of Plastic Surgery, Fellow of the International Society of Aesthetic Plastic Surgery, American College of Surgery, and International College of Surgery and member of the American Society of Plastic Surgery, American Academy of Cosmetic Surgery and RealSelf Hall of Fame.)

Silicone biopolymers are being used throughout the world for facial and body volume augmentation. Results are longer-lasting that Juvederm or Restylane. 
Bellafill and Artefill are known to cause granulomas and permanent nodules with swelling. This is not the case for everyone. Silicone biopolymers can also cause similar chronic inflammatory conditions. 
In my practice, I specialize in the removal of Bellafill and Artefill injections, in addition to silicone biopolymers, from the face and body. Initially, treatments are non-surgical with corticosteroids and immune modulators. If unable to be corrected, we can also perform surgery in some cases. 
Silicone biopolymers can also be removed from the body if there are signs of migration or inflammation. All of these filler-types should be removed as early as possible. 
Lastly, our office is conducting ongoing studies of plasma-assisted corticosteroid application, which allows for diffusion of the treatment medication in superficial tissue without causing atrophy. 
Best,
