Fortunately not. Silicone breast implants have evolved over time. Early generations demonstrated thin shells with low viscosity silicone. These implants were prone to rupture and leakage. The latest generation of silicone implants are made of cohesive gel. The silicone does not bleed through the implant shell or migrate if rupture occurs. If the implant shell is compromised, it is generally an incidental finding noted on imaging (ultrasound or MRI). The silicone will not travel throughout the body.
