Breast augmentation is one of the most commonly performed cosmetic surgeries in the world, and for most people it goes smoothly. But “safe” is relative. The procedure carries real risks, some appearing within weeks and others developing years later. About 20% of patients need a second surgery within six to ten years, and the FDA now requires a boxed warning on all breast implant labeling, the strongest type of safety alert for a medical device. Understanding the full picture helps you weigh whether those risks are acceptable for you.
What the FDA Requires Before Surgery
The FDA restricted the sale and distribution of breast implants specifically to ensure patients receive adequate risk information before making a decision. All legally marketed breast implants now carry a boxed warning, and manufacturers must include a patient decision checklist. Your surgeon is required to review this checklist with you, covering the known risks and benefits. You must have the opportunity to initial and sign it, and the implanting physician signs it too. This isn’t a formality. It exists because the risks are numerous enough that regulators wanted a documented process confirming you understood them.
Short-Term Surgical Complications
The immediate post-operative risks are relatively low. In a study of over 1,100 patients, hematoma (a collection of blood near the surgical site) was the most common short-term complication at 2.7%, typically appearing within the first 14 hours. Deep surgical site infection occurred in about 0.5% of patients, usually showing up around two weeks after surgery. These numbers are consistent with broader research showing hematoma rates of 1 to 3% and infection rates around 1% or less. Most of these complications are manageable but may require additional treatment or, in some cases, a return to the operating room.
Capsular Contracture
Your body naturally forms a thin layer of scar tissue around any implanted object. In some people, that scar tissue tightens and squeezes the implant, a condition called capsular contracture. It can make the breast feel firm, look distorted, or become painful. Estimates put the rate at 5 to 19% for cosmetic augmentation patients and higher (19 to 25%) for those receiving implants after mastectomy. Severity ranges from barely noticeable firmness to a visibly misshapen, painful breast that requires surgical correction. Capsular contracture is one of the leading reasons people end up back in the operating room.
Reoperation Is Common
Breast implants are not lifetime devices. Reoperation rates climb steadily over time: roughly 10% of patients need additional surgery within two years, and that figure reaches about 20% by six to ten years. Longer-term data from manufacturer studies show even higher numbers. In one ten-year follow-up of a widely used silicone implant, the reoperation rate reached 28% at six years and 36% at ten years. Another implant style showed a 30% reoperation rate at the ten-year mark.
Reasons for reoperation include capsular contracture, implant rupture, changes in size preference, implant displacement, and cosmetic dissatisfaction. This doesn’t mean the original surgery “failed” in every case, but it does mean you should plan for the likelihood of at least one additional procedure over your lifetime.
Implant Rupture Over Time
Modern silicone implants are more durable than earlier generations, but they still break down. In a ten-year MRI study of one cohort of augmentation patients, confirmed rupture occurred in about 10% of people (affecting roughly 6% of individual implants). When suspected ruptures were included, the rate rose to about 18% of augmentation patients.
Silicone ruptures are often “silent,” meaning you can’t feel or see any change. The FDA recommends periodic imaging (MRI or ultrasound) to check implant integrity starting a few years after placement. Saline implants, by contrast, deflate noticeably when they rupture because the saltwater is absorbed by the body. Either way, a ruptured implant typically needs surgical replacement.
Breast Implant Illness
A growing number of patients report systemic symptoms they attribute to their implants, a condition commonly called Breast Implant Illness (BII). No definitive scientific link has been proven, and no lab test or physical finding can diagnose it. But a large meta-analysis of over 10,500 patients found a statistically significant correlation between having implants and experiencing these symptoms.
The most commonly reported symptoms are joint complaints (39% of affected patients), fatigue (27%), muscle pain or weakness (25%), cognitive problems like brain fog (22%), and generalized pain (17%). The association was strongest for fatigue, muscle weakness, and cognitive dysfunction, with implant patients roughly three times more likely to report these symptoms. Silicone-filled implants and ruptured implants appeared more likely to be associated with these symptoms than saline or intact implants. Patients who had their implants removed reported somewhat fewer symptoms overall.
The medical community has not reached consensus on BII as a formal diagnosis, and the symptoms overlap with many other conditions. Still, the pattern is consistent enough that the FDA includes it in implant risk information, and many surgeons now discuss it during consultations.
Rare but Serious: Implant-Associated Cancers
Breast implants have been linked to a rare cancer of the immune system called Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL). This is not breast cancer. It develops in the scar tissue capsule surrounding the implant and is most strongly associated with textured-surface implants. Incidence rates vary widely depending on the data source, ranging from roughly 1 in 250 to 1 in 100,000 patients with textured implants. In the U.S., incidence peaked around 2020 and has been declining since, partly because some textured implants were pulled from the market. Globally, rates dipped in 2022 but rose again in 2023 and 2024.
More recently, the FDA has also flagged reports of squamous cell carcinoma (a type of skin cancer) developing in the capsule around implants. As of early 2023, there were 19 published cases in the medical literature and 24 reports submitted to the FDA. These have been found with both textured and smooth implants, and with both saline and silicone. The numbers are very small, but the FDA is actively tracking them and recommends that patients and doctors report any new cases.
Impact on Mammograms
Breast implants do not increase your risk of breast cancer, but they do make it harder to detect. Implants can obscure breast tissue on mammograms, reducing the exam’s sensitivity. Radiologists use a technique called displacement views, physically pushing the implant back to get a clearer image of the breast tissue. These views detect significantly more abnormalities than standard compression alone, but they don’t catch everything.
Implant placement matters here. With implants positioned above the chest muscle (subglandular), about 26.5% of abnormal findings would be missed if only displacement views were used without standard views. With implants behind the muscle (subpectoral), that gap drops to about 5%. This is one reason many surgeons now prefer submuscular placement, and why mammography for augmented patients involves extra views and sometimes supplemental imaging like ultrasound or MRI.
Breastfeeding After Augmentation
If future breastfeeding matters to you, the research is reassuring on one common concern: incision location does not appear to make a significant difference. Studies comparing incisions made below the breast versus around the areola found breastfeeding continuation rates of 47% and 46%, respectively, with no statistically significant difference. While there has been some evidence that submuscular saline implants may reduce breastfeeding success by about 25%, the surgical approach (periareolar versus inframammary) itself does not appear to be a deciding factor.
Weighing the Decision
Breast augmentation is not unusually dangerous compared to other elective surgeries. Infection and bleeding rates are low, and life-threatening complications are rare. But the long-term picture is more complex than many people expect going in. The high probability of reoperation, the possibility of systemic symptoms, the need for ongoing implant monitoring, and the small but real risk of implant-associated cancers all factor into the equation. For most patients, safety isn’t a single yes-or-no answer. It depends on which type of implant you choose, where it’s placed, how you respond to the device over years, and whether you’re prepared for the possibility that this won’t be a one-time procedure.
