Can silicone implants burst when squeezed to hard?

Our own bodies give out with time as does our cars and just about everything else in life and so is the case for implants. For silicone implants prior to 2006, ruptures occur at rates of approximately 1-2% per year for the first ten years then markedly increases after that time period. Implants are designed to take a lot of compressive forces like hard squeezing, but if the implants are more than a decade this may of course be a contributing factor.  A rupture or deflation of the implant may be experienced at any point after the initial augmentation; this complication may be increased by an under-filling or overfilling of saline solution into the implant, excessive compression, trauma, and other causes. (If the implant shell if not filled with the correct amount of saline, there may be a crease or fold in the shell which often leads to a rupture). You will be able to self-diagnose the need for an implant exchange (if using a saline implant) because if the current implant ruptures, the breast will shrink to approximately its preoperative size. A silicone implant that has a rupture is usually noted on a routine mammogram or MRI scan. In either case although the situation needs to be corrected on a timely basis, it is not dangerous to your health from our current knowledge base. Silicone implants after 2006 are more cohesive and less likely to leak or have silicone migration.

Implants are made of a durable silicone shell that can withstand tons and tons of pressure. Simply squeezing them with your hand will probably not rupture the implant - you'll do more harm to your breast tissues than the implant itself.  

Thank you for your question.  Of course anything is possible, however simple squeezing of breasts with implants should not rupture the implant.  Typically significant trauma such as an automobile accident, or high diving with a "belly flop" has been associated with rupture of silicone breast implant.
