How Hard Can You Squeeze Silicone Gel Implants Without Causing Rupture?

It would take a very powerful force to rupture your implants. Not that the implants are considered lifetime devices, but they are made to last and are quite durable. You would most likely damage your own breast tissue before your implants would be hurt.

The implant is designed to withstand 3 times your body weight in force.  You should be able to stand on the implant and not rupture it.  With the new form of breast implants produced after 2009 there is little chance of the implant gel material migrating since the gel is more cohesive than it was prior to this time.  Therefore it may be difficult to tell if it is ruptured since the implant tends to keep its original shape. The problem is non an emergency.  You would need some type of diagnostic study to determine if it was actually ruptured such as a  mammogram, MRI or ultrasound.
