With the approval of silicone breast implants by the FDA, new recommendations are in effect for detection of implant leakage. The FDA wants women with these implants to get MRI's every 2 years. One criticism of this suggestion is that the cost of an MRI is very expensive.
"In an attempt to address the shortcomings of current tests, researchers at The University of British Columbia have designed a rapid method to detect leakage events. A stable synthetic tracer molecule added to silicone breast implant filler is detected in a patient’s hair, blood or urine, following leakage or rupture. This non-invasive test is sensitive, inexpensive, accessible, and decreases health risks associated with silicone breast implants. "
This is a clever solution to the silicone problem. We'll see if it comes to fruition in the coming years.
