Do saline/silicone implants cause fungus or mold inside the body?

I have heard of the concern of mold forming in saline implants, but I have never actually seen it nor have I heard about it from another surgeon.  It must be extremely rare and the risk quite low.

The short answer is extremely rare and the reasons are:1) breast implants are manufactured under the highest sterile standards and our regulated/monitored by Governmental agency's.  They have/are under constant monitoring.2)Board Certified Plastic Surgeons have gone through extensive infection prevention training. Most Plastic Surgeons will give peri operative antibiotics and intra operatively, prior to insertion of the implants, rinse out the pocket with a solution that contains several antibiotics. 3)Accredited/certified Surgical Operating rooms have to meet very high standards to attain accreditation are required to perform rigorous and continuous  sterility checks and monitor surgical outcomes as they relate to infections. For more detailed information please go to the manufactures websites: Allergan.com, Mentor.com, and Sientra.com.Lastly,  make sure your Plastic Surgeon is certified by the American Board of Plastic Surgery and he/she operates in a accredited operating room.

The answer is NO.  Breast implants are the most studied medical devices in the history of humanity.  Provided they are used as they were designed to be used by appropriately certified surgeons in appropriately accredited facilities, they are safe, and unassociated with micro-organisms of any type.  That being said, we humans live in a world of micro-organisms, including those that make their homes in our gastro-intestinal tract, under our fingernails, in our respiratory tract, inside our sebaceous glands, and even inside the lactiferous ducts of our breasts.  When implants are associated with microbes, the source is most often the host.
