According to the American Society of Plastic Surgeons (ASPS), over 300,000 breast augmentations are performed per year in the United States. Although exact numbers are not reported, the total number of women living with implants is in the millions. Silicone breast implants have been in use for nearly 6 decades and have undergone significant changes in design and use. The question often arises as to how accurate a mammogram is in detecting a ruptured implant. The answer to this question is that it depends.
Mammograms are more accurate in identifying extra capsular rupture (extracapsular leakage) than intra capsular rupture (intracapsular leakage) when it comes to breast implant rupture. To explain more fully, all breast implants will develop a layer of scar tissue around them that is referred to as its “capsule”. Most capsules are thin, soft, flexible and are completely normal. Intra-capsular rupture means the leaked silicone remains contained within the fibrous scar tissue capsule, often producing no symptoms and may go undetected for years, while extra capsular rupture involves silicone escaping into surrounding tissue. All implants have a lifespan and do not last forever. Modern cohesive gel implants last significantly longer than earlier versions, but manufacturers do not claim that any breast implant will last a lifetime. They need to be replaced or removed periodically, and additional surgery such as breast revision may be required to address complications like leakage, hardening, or aesthetic concerns. When a silicone implant leaks, the free silicone will initially be contained by the capsule. This capsule, while intact, prevents silicone from reaching the breast tissue. However, with time, the capsule can break and this allows the silicone to leak out into the breast itself. Once out into the breast, silicone can be more difficult to remove in its entirety. Ruptured implants can also affect the breast pocket, and its management is important during revision procedures for implant stability and aesthetic results.
MRI remains the most accurate method of detecting intra capsular rupture of silicone implants and can reveal the “linguini sign,” indicating a collapsed implant shell within the capsule. This test, therefore, remains the gold standard for monitoring silicone implants for leakage. Another test modality for implant surveillance is ultrasound, which is an FDA-approved alternative for routine screening in asymptomatic patients, offering lower cost and wider availability compared to MRI, but is highly operator-dependent. Ultrasound can detect both extracapsular and intracapsular ruptures. Although MRIs are sensitive, they can be expensive if insurance doesn’t cover them. For this reason, many plastic surgeons will recommend that a woman consider replacing silicone implants every 10 years. The only way to confirm an implant rupture or leak is through surgery to visualize the implant, although MRI studies are non-invasive and can be relatively accurate.
Diagnosing a silicone implant rupture early is important. The FDA recommends that an initial MRI or ultrasound be done around 5 to 6 years after placement of a silicone implant to detect a silent rupture. Not all ruptures present with symptoms, and most breast implant rupture patients do not manifest clinically significant signs or symptoms and are classified as having ‘silent’ ruptures, which is why these imaging modalities are important. The majority of silicone implant ruptures are clinically undetectable and pose no significant health risks, as supported by medical literature. This is then followed by repeat MRI or ultrasound every 2-3 years. Diagnosing a leaking silicone implant early can prevent extra capsular rupture or reduce the chance of developing capsular contracture. Rupture rates and rupture risk vary between implant types, with modern cohesive gel implants having significantly lower failure rates compared to earlier generations. Rupture rates increase significantly after 6 years, with 15% of modern implants expected to rupture between the third and tenth year after implantation, and the risk of breast implant ruptures increases substantially after the first decade, making awareness and regular monitoring essential for maintaining breast health.
Understanding Breast Implant Illness
Breast implant illness (BII) is a term used to describe a collection of systemic symptoms that some women experience after receiving breast implants, particularly silicone breast implants. These symptoms can include persistent fatigue, joint pain, brain fog, and unexplained muscle aches. While the exact cause of breast implant illness remains unclear, ongoing research suggests that the body’s immune response to the implant—especially in cases of silicone implant rupture—may play a significant role.
One of the challenges with silicone implant ruptures is that they can be “silent,” meaning there are no obvious signs or symptoms. This makes detecting silicone implant ruptures especially important for maintaining breast implant safety. Magnetic resonance imaging (MRI) is the most reliable tool for identifying ruptured silicone breast implants, as it can detect even small leaks that might not be apparent on physical examination or other imaging tests. The FDA recommends regular screenings with MRI to monitor breast implant integrity and to catch suspected implant rupture early, even if you are not experiencing symptoms.
Ruptured breast implants, whether saline or silicone, can lead to a range of complications. For saline implants, a rupture is usually noticeable as the breast quickly loses volume and shape due to the harmless absorption of the sterile saline solution by the body. In contrast, ruptured silicone implants may not change breast size or shape immediately, but the silicone gel can migrate into surrounding tissue, potentially causing breast pain, capsular contracture (hardening of the scar tissue around the implant), or breast asymmetry. In some cases, silicone from ruptured implants can move to lymph nodes or other areas, making surgical removal more complex.
Women with breast implants should be vigilant for any changes in breast shape, size, or texture, as well as systemic symptoms like joint pain, fatigue, or unexplained discomfort. These could be signs of implant rupture or breast implant illness. Regular check-ups with a board-certified plastic surgeon, self-examinations, and adherence to the FDA’s guidelines for regular screenings are essential steps to monitor breast implant safety and detect issues early.
The risk of implant rupture increases as implants age, so women with older implants should be especially proactive about monitoring. While saline implants are less likely to cause silent rupture, they are still medical devices that can fail over time. If a rupture is detected, breast implant removal or revision surgery may be necessary. In some cases, breast reconstruction may be recommended to restore breast shape and size after implant removal.
To reduce the risk of implant rupture and related complications, women should avoid trauma to the chest, follow a healthy lifestyle, and promptly address any unexplained symptoms with their healthcare provider. By staying informed and working closely with their medical team, women can take important steps to protect their breast health and overall well-being.
In summary, understanding breast implant illness and the risks associated with implant rupture is crucial for anyone with breast implants. Regular screenings, self-awareness, and open communication with your plastic surgeon can help detect problems early and ensure the best possible outcomes for your health and peace of mind.
