When a breast implant ruptures, what happens next depends almost entirely on the type of implant. A saline implant deflates visibly within days, making the rupture obvious. A silicone implant can rupture without any noticeable change at all, sometimes going undetected for years. Neither scenario is a medical emergency, but both require attention and typically lead to surgical replacement.
Saline vs. Silicone: Two Very Different Experiences
If you have saline implants, a rupture is hard to miss. The saltwater solution leaks out quickly, usually over a few days, and the affected breast looks noticeably smaller or deflated. Your body absorbs the saline harmlessly since it’s the same kind of sterile salt water used in IV bags. The shell of the implant stays in place and needs to be surgically removed, but there’s no concern about the leaked fluid itself.
Silicone implant ruptures are a different story. Most people with a ruptured silicone implant have no symptoms at all. These are called “silent ruptures,” and they’re the most common type. The silicone gel doesn’t get absorbed by the body the way saline does. Instead, it stays put or slowly spreads into surrounding tissue, which is why you can walk around with a ruptured silicone implant and never realize it.
Where the Silicone Goes
Your body forms a natural scar tissue shell, called a capsule, around every breast implant. When a silicone implant ruptures, the gel often stays trapped inside that capsule. This is an intracapsular rupture, and it’s the more common scenario. The breast may look and feel completely normal because the capsule is holding everything in place.
The more concerning situation is an extracapsular rupture, where silicone gel leaks beyond the capsule and into the surrounding breast tissue. When this happens, the silicone can trigger inflammation and form hardened lumps of scar tissue called granulomas. You might feel a new lump or firmness in the breast, notice tenderness or vague pain, or still feel nothing at all. In some cases, silicone from an extracapsular rupture travels through the lymphatic system to lymph nodes in the armpit, and in rare instances, it has been found even farther from the breast. Silicone lymph node involvement typically develops 6 to 10 years after augmentation.
Capsular Contracture After Rupture
One of the most significant consequences of a silicone implant rupture is a sharply increased risk of capsular contracture, a condition where the scar tissue capsule tightens and squeezes the implant. This makes the breast feel hard, look distorted, and sometimes causes pain. A 2024 study comparing breasts within the same patients found that capsular contracture occurred in 50% of breasts with a ruptured implant, compared to 24% of breasts where the implant was intact. That’s roughly a fourfold increase in risk. The likely mechanism is that leaking silicone triggers ongoing inflammation, which causes the capsule to thicken and contract over time.
Newer Implants Behave Differently
Not all silicone implants leak the same way. Older implants used a more liquid silicone gel that could flow freely once the shell broke. Starting in the early 1990s, manufacturers introduced highly cohesive “gummy bear” implants with a thicker, form-stable gel. When these newer implants rupture, the gel tends to hold its shape rather than spreading into surrounding tissue. This doesn’t mean rupture is harmless with newer implants, but the risk of silicone migration is lower compared to older models. If you have implants from the 1980s or earlier, the potential for gel to spread is considerably greater.
How Ruptures Are Detected
Because silicone ruptures are usually silent, imaging is the only reliable way to find them. Physical exams miss most intracapsular ruptures. The FDA recommends that people with silicone implants get their first ultrasound or MRI screening 5 to 6 years after surgery, then every 2 to 3 years after that, even if they have no symptoms.
MRI has long been considered the gold standard for detecting ruptures, but recent research shows ultrasound performs nearly as well, with 95% sensitivity and 96% specificity compared to MRI. Ultrasound is faster, cheaper, and more widely available, which makes the screening schedule more practical to follow. Either option can reliably catch a rupture before silicone has a chance to migrate.
What Surgery Looks Like
Once a rupture is confirmed, you have two basic options: surgical removal or continued monitoring. For a saline rupture, surgery is straightforward. The deflated shell is removed, and a new implant can be placed during the same procedure if you choose.
For silicone ruptures, the surgery depends on where the gel has gone. If the rupture is recent and contained within the capsule, a surgeon can remove the implant and clean out the silicone. In many of these cases, the capsule itself can stay in place. If silicone has infiltrated the capsule wall, the surgeon typically removes the entire capsule along with the implant, a procedure called total capsulectomy. This is more involved and can affect breast shape afterward, especially if you don’t have much natural breast tissue.
Extracapsular ruptures are the most complex. When silicone has spread into surrounding tissue, it can be difficult to retrieve completely. Some patients need multiple surgeries to remove as much silicone as possible, with implant replacement delayed until the cleanup is finished. Granulomas embedded in tissue are particularly challenging because the silicone becomes encased in scar tissue that has to be carefully dissected out.
Silent Ruptures Without Symptoms
If a routine screening catches a silent intracapsular rupture and you feel fine, surgery isn’t always urgent. Some people and their surgeons opt for observation, monitoring the rupture with periodic imaging rather than operating immediately. This is a reasonable approach in certain cases because intracapsular ruptures can remain stable for years. The trade-off is the risk that the rupture could progress to extracapsular over time, making eventual surgery more complicated. The longer silicone sits against tissue, the greater the inflammatory response and the higher the chance of capsular contracture developing.
For extracapsular ruptures, the calculus shifts toward surgery. Free silicone in the tissue continues to provoke inflammation and can migrate further. While most silicone stays relatively local, documented cases show it reaching axillary lymph nodes and, in rare instances, distant sites in the body through the bloodstream. These cases are uncommon, but they underscore why catching ruptures early through regular screening matters.
