The most common signs of leaking breast implant are a noticeable change in breast size or shape, deflation, firmness, swelling, tenderness, or a lumpy feeling. Saline implant leaks usually cause the breast to shrink quickly and look smaller, while silicone leaks are often “silent” and may show no obvious symptoms at all.
Â
Breast implants are designed to last many years, but they are not lifetime devices. Over time, the shell can weaken or tear, allowing the filler material to escape. This comprehensive guide explains the warning signs, causes, and treatment options for a ruptured implant.
Â
A breast implant rupture happens when the outer shell develops a tear, hole, or weak spot, allowing the filler – either sterile saline (saltwater) or silicone gel – to leak out. The way a rupture shows up depends on which type you have.
Â
Saline ruptures are usually easy to spot because the saltwater leaks out quickly and the breast loses volume. Silicone gel is thicker and tends to stay close to the shell, which is why these are often called “silent ruptures.” A rupture is not typically a medical emergency, but it does require evaluation by a qualified plastic surgeon.
Â
While implant shells are strong, they can be compromised for several reasons:
Age of the implant. This is the most common reason. Over many years, the shell naturally weakens. The FDA does not consider breast implants to be lifetime devices.
Normal wear and tear. Like any medical device, implant shells break down after years of use.
Capsular contracture. The body forms a scar-tissue capsule around any implant. When this tightens, it can place enough stress on the shell to cause a rupture.
Trauma. A significant impact to the chest, such as from a car accident or hard fall, can damage an implant.
Damage during surgery. Although rare with experienced surgeons, an implant can be inadvertently nicked during the initial breast augmentation or a revision procedure.
Overfilling or underfilling (saline implants). Improperly filled saline implants can develop folds or creases that weaken over time.
Iatrogenic damage. Damage can occur during other procedures, such as biopsies, if the instrument contacts the implant.
Manufacturing flaws. Although uncommon, a weak spot in the shell can lead to early failure.
Â
Many ruptures occur without a clear cause. Normal movements, exercise, and properly performed mammograms are highly unlikely to cause a rupture.
Â
When a saline implant ruptures, the effects are usually immediate and obvious. The sterile saltwater is harmlessly absorbed by your body, so you will not feel a leak or see any fluid – the change in volume is the key indicator. Common signs include:
Rapid deflation. The affected breast may shrink within a few hours or days.
Noticeable size difference. One breast may look clearly smaller than the other.
Change in shape. The breast may lose its rounded fullness and appear flat, misshapen, or wrinkled.
Loss of firmness. The treated breast may feel softer or empty.
Â
This event is not dangerous, but the implant will need to be removed or replaced to restore symmetry and volume.
Â
A silicone rupture is often called a “silent rupture” because the cohesive gel tends to stay within the shell or surrounding scar tissue. You may not experience any immediate signs, but over weeks, months, or years you might notice:
Changes in breast shape or size. The breast may appear smaller, asymmetrical, or have an irregular contour.
Firm lumps or knots. Leaked silicone can cause hard lumps (silicone granulomas) around the breast or armpit.
Swelling or tenderness. The breast may feel sore, swollen, or full.
Pain, burning, or tingling. Irritation of surrounding tissue or nerves can cause discomfort, aching, tingling, or numbness.
Hardening of the breast. Increased firmness can signal scar tissue tightening around a leak, often associated with capsular contracture.
Â
Because these symptoms can be subtle or absent, the FDA recommends regular screening to monitor silicone implants.
Â
When cohesive gel leaks but remains within the scar tissue capsule (an intracapsular rupture), there are typically no immediate health concerns. However, if the shell and capsule both tear (an extracapsular rupture), the silicone can migrate into surrounding tissue. This can lead to:
Silicone granulomas. The immune system may form hard, sometimes painful lumps of inflamed tissue that can make self-exams more difficult.
Capsular contracture. Free silicone can trigger or worsen contracture, causing the breast to become hard, misshapen, and painful.
Lymph node involvement. In rare cases, silicone can travel to lymph nodes in the armpit, causing them to enlarge.
Â
Studies have not found a link between ruptured silicone implants and systemic diseases like autoimmune disorders or breast cancer. Leaving a silicone leak untreated can make corrective surgery more involved later, so acting early keeps treatment simpler.
Â
You can play an active role in spotting a problem early. Pay attention to how your breasts normally look and feel:
Do regular self-checks. Gently feel each breast every month, noting their normal shape, size, and firmness.
Compare both sides. Watch for new asymmetry – is one sitting lower, looking smaller, or shaped differently?
Notice texture changes. Be alert to new lumps, hard areas, ripples, or changes in firmness.
Track how you feel. Note any persistent pain, swelling, aching, tingling, or numbness.
Know your implant type. Saline ruptures show up quickly through obvious deflation, while silicone ruptures may need imaging to confirm.
Â
If you spot any warning signs – or if it has been several years since your surgery – don’t panic, but do schedule a consultation for a professional evaluation.
Â
For saline implants, a physical exam by an experienced plastic surgeon is usually all that’s needed to confirm the rupture due to visible deflation. Diagnosing a silent silicone rupture requires medical imaging:
MRI (Magnetic Resonance Imaging). Considered the most accurate and reliable method for detecting silicone ruptures, clearly showing the shell, gel, and any free silicone. The FDA recommends a first MRI five to six years after surgery, then every two to three years thereafter.
High-resolution ultrasound. A quicker, lower-cost option performed by a technician experienced in breast imaging. While less sensitive than MRI, it’s a useful screening tool.
Physical exam. Your surgeon can examine your breasts, ask about symptoms, and review your implant history.
Â
A mammogram is not effective for diagnosing a rupture but remains essential for routine breast cancer screening – always inform your technician that you have implants.
Â
Once a rupture is confirmed, the standard recommendation is to remove or replace the implant. The right approach depends on your implant type, the extent of the leak, and your goals.
Â
This is a common and well-understood breast revision procedure. Options typically include:
Implant removal and replacement. The most common choice. The ruptured implant is removed and a new one is placed to restore volume and shape – a great opportunity to change implant size, type (e.g., from saline to silicone), or profile.
Implant removal with a breast lift. If you no longer want implants, removing them without replacement can leave the breasts deflated and saggy. A breast lift can be performed at the same time to remove excess skin and reshape the breast.
Capsulectomy. Your surgeon may remove some or all of the scar tissue capsule, especially with capsular contracture or an extracapsular silicone rupture.
Â
For silicone ruptures, the surgeon also removes any leaked gel and cleans the area before placing a new implant if desired. This is a natural time to refresh your results with breast augmentation using a different size or type.
Â
Schedule a consultation with a plastic surgeon if you notice:
A sudden or gradual change in breast size or shape
Deflation or loss of fullness in one breast
New lumps, firmness, or hardening
Swelling, tenderness, or unusual sensations
Any concern after a strong impact to the chest
Â
Even without symptoms, if you have silicone implants older than five years, schedule a screening evaluation and ask about imaging. Catching a leak early keeps treatment simpler.
Â
The key signs of leaking breast implant include changes in breast size or shape, deflation, firmness, swelling, lumps, or new discomfort. Saline ruptures tend to be obvious and quick, while silicone ruptures can be silent and may only show up on imaging like an MRI or ultrasound.
