Implant rupture means the outer shell of the implant has developed a tear or hole. It is one of the recognised long-term risks of breast implants, and the chance of it happening increases the longer an implant has been in place — one of the main reasons implants are not considered lifetime devices. Rupture is usually not a medical emergency, but it does normally mean the implant needs to be removed or exchanged, so understanding the signs and how it is detected is important.
Saline rupture versus silicone rupture
What happens when an implant ruptures depends on what it is filled with:
- Saline rupture (deflation). The salt water escapes and is harmlessly absorbed by the body, so the breast visibly loses volume, often over hours to days. It is obvious — see implant deflation.
- Silicone rupture. Modern cohesive gel tends to stay together rather than leaking out, so a rupture often causes no obvious change. The gel is usually contained within the scar capsule (intracapsular rupture); less commonly it spreads beyond the capsule (extracapsular rupture).
What causes rupture?
Rupture is usually due to gradual wear of the shell over time, but it can also follow trauma, capsular contracture placing stress on the implant, or damage during surgery. There is no precise expiry date, and many implants remain intact for well over a decade — but the cumulative chance of rupture rises year on year, which is why long-term awareness and follow-up matter.
Signs to look out for
Because a silicone rupture can be silent, there may be no symptoms at all. When signs do occur, they can include:
- A change in the shape, size or firmness of the breast.
- A new lump or lumpiness.
- Discomfort, tenderness or, occasionally, swelling.
- For saline: a clear, relatively sudden loss of volume on one side.
How rupture is detected
Imaging is key, especially for silicone implants:
- MRI is the most sensitive test for detecting silicone rupture and can identify a silent rupture before any symptoms appear.
- Ultrasound is also widely used and is less expensive and more accessible.
Some guidance, including from the FDA, suggests considering periodic screening of silicone implants for silent rupture; discuss the most appropriate approach for you with your surgeon. If you notice any change in your breast, seek review rather than waiting.
Is a ruptured implant dangerous?
For saline implants, the leaked salt water is harmless. For silicone, current evidence does not establish that a contained gel rupture causes serious systemic illness, but a ruptured implant should still be removed or exchanged, both because gel can occasionally migrate and because a damaged implant no longer performs as intended. If gel spreads beyond the capsule (extracapsular rupture), it can sometimes cause lumps or reach nearby lymph nodes, which is a further reason not to leave a known rupture untreated.
Treatment
A confirmed rupture is treated surgically by removing the implant and, in most cases, exchanging it for a new one — often combined with removal of the old capsule and any free gel. This is a form of revision surgery. Some manufacturer warranties contribute towards the cost of replacing a ruptured implant within a defined period, though surgical fees are usually still payable — check your implant's written warranty. See replacement cost.
Frequently asked questions
How will I know if my implant has ruptured?
You may not — silicone ruptures are often silent. Saline ruptures cause obvious deflation. Report any change in breast shape, size, firmness or new lumps to your surgeon, and consider periodic imaging for silicone implants.
Is a ruptured silicone implant a medical emergency?
It is generally not an emergency, but a confirmed rupture should be assessed and the implant removed or exchanged rather than left. Seek a non-urgent review with your surgeon if rupture is suspected.
How often should silicone implants be scanned?
There is no single fixed schedule, but some guidance suggests periodic MRI or ultrasound to check for silent rupture. Discuss the right approach and timing for your implants with your surgeon.
