When a breast implant ruptures, the shell breaks open and its contents leak out. What happens next depends entirely on whether the implant is filled with saline (saltwater) or silicone gel. A saline rupture is obvious within hours as the breast visibly deflates. A silicone rupture is far more subtle and can go undetected for years, earning it the name “silent rupture.” Neither type is considered a medical emergency, but both require surgical removal or replacement.
Saline vs. Silicone: Two Very Different Experiences
A saline implant that ruptures leaks sterile saltwater, which your body simply absorbs. The affected breast noticeably shrinks or changes shape, sometimes within hours. There’s no mystery about what happened, and the saline itself poses no health risk.
Silicone ruptures are a different story. Modern silicone gel is thick and cohesive, so when the shell breaks, the gel often stays in place rather than flowing freely. Most people with a ruptured silicone implant have no symptoms at all and don’t realize anything has changed. The rupture is frequently discovered incidentally during routine imaging. When symptoms do appear, they can include a change in breast shape, firmness, swelling, or vague tenderness.
Where the Silicone Goes
Your body forms a natural scar tissue lining, called a capsule, around every breast implant. When silicone gel leaks but stays contained within that capsule, it’s called an intracapsular rupture. This is the more common scenario and the least problematic, since the silicone hasn’t spread into surrounding tissue.
An extracapsular rupture is more serious. Silicone gel escapes beyond the scar tissue capsule and infiltrates the surrounding breast tissue, triggering inflammation and the formation of granulomas, which are small lumps of immune cells that wall off the foreign material. You might feel a palpable lump or notice breast irregularity, though some extracapsular ruptures still produce no obvious symptoms.
In uncommon cases, silicone can travel further. It enters the lymphatic system and collects in the lymph nodes under the arm, a condition called silicone lymphadenopathy that typically develops 6 to 10 years after implant placement. In rare instances, silicone has been found to spread through the bloodstream to distant sites in the body, provoking foreign body reactions wherever it lands.
Capsular Contracture Risk
One of the most significant consequences of a silicone rupture is an increased risk of capsular contracture, where the scar tissue capsule around the implant tightens, hardens, and squeezes the implant. A 2025 study comparing breasts with ruptured implants to intact implants within the same patients found capsular contracture in 50% of breasts with ruptured implants versus 24% of breasts with intact implants. The odds of developing contracture were 4.5 times higher on the ruptured side. This effect was strongest with older, less cohesive silicone gel formulations, where the odds climbed even higher. Highly cohesive (“gummy bear”) implants did not show the same association, likely because their firmer gel is less prone to leaking into the capsule wall and causing inflammation.
How Ruptures Are Detected
MRI is the most reliable imaging tool for identifying silicone implant ruptures. Across multiple studies, MRI detects ruptures with about 87% sensitivity and 90% specificity. Ultrasound is less accurate, catching roughly 61% of ruptures, with specificity around 76%. MRI performs best when there are already symptoms suggesting a problem. In completely asymptomatic patients, its sensitivity drops to about 76%.
The FDA recommends that people with silicone implants get an MRI or ultrasound starting 5 to 6 years after surgery, then every 2 to 3 years after that. These screenings are designed to catch silent ruptures before silicone has a chance to migrate.
How Common Are Ruptures?
Implants don’t last forever, but modern shells are more durable than earlier generations. A 10-year study of nearly 1,000 silicone implants found a cumulative rupture risk of about 3.5% per implant over a decade. Rates vary by manufacturer. Some studies have reported 10-year rupture rates closer to 9% for certain brands. The risk climbs with time, and most plastic surgeons consider implants to have a functional lifespan of 10 to 20 years, after which the likelihood of shell failure increases substantially.
What Surgery Looks Like
A ruptured implant needs to be surgically removed regardless of whether you’re experiencing symptoms. For intracapsular ruptures, the procedure is relatively straightforward. The surgeon removes the implant and, if silicone has soaked into the capsule lining, removes the entire scar tissue capsule as well. If the rupture is very recent and the gel hasn’t spread, the capsule can sometimes be left in place.
Extracapsular ruptures are more complex. Silicone that has infiltrated the surrounding breast tissue is difficult to retrieve completely, and some patients need multiple surgeries to remove as much gel as possible. Implant replacement is typically delayed to allow the tissue to heal first.
Recovery after implant removal generally involves one to two weeks of restricted activity, including no driving. Strenuous exercise and heavy lifting are off limits for longer, and soreness or tenderness can persist for up to six weeks.
Insurance and Warranty Coverage
Most major implant manufacturers offer lifetime warranties that cover the cost of replacement implants if a rupture is confirmed. Mentor, for example, provides up to two replacement implants of the same or similar style at no charge for the lifetime of the patient. If the rupture happens within the first 10 years, some manufacturers also offer financial assistance toward surgical costs that insurance doesn’t cover. The specifics vary by brand and by the warranty plan selected at the time of the original surgery, so it’s worth reviewing your paperwork or contacting the manufacturer directly.
Health insurance coverage for rupture-related surgery depends on the original reason for the implant. Reconstruction after mastectomy is more consistently covered than cosmetic augmentation. Even with cosmetic implants, though, many insurers will cover removal of a ruptured device as a medically necessary procedure while declining to cover replacement with a new implant.
