Some swelling, bruising, tightness, and discomfort are expected during breast augmentation recovery. However, new, worsening, one-sided, or persistent symptoms may indicate breast augmentation complications that require evaluation.
Knowing what to watch for can help patients raise concerns promptly. Only a qualified medical professional can determine whether a symptom is part of routine healing or a complication.
What Are the Common Complications of Breast Augmentation?
The possible complications of breast augmentation may relate to the operation, healing process, or implant. Some develop shortly after surgery, while others appear months or years later.
Potential complications include:
- Infection
- Bleeding or hematoma
- Seroma, or fluid accumulation
- Capsular contracture
- Implant rupture or deflation
- Implant displacement or asymmetry
- Visible or palpable rippling
- Changes in breast or nipple sensation
- Delayed wound healing or abnormal scarring
Breast implants are not lifetime devices, and the likelihood of certain problems may increase over time. This does not mean implants must automatically be replaced after a fixed number of years.
Understanding the Risks and Complications of Breast Augmentation Surgery
The risks and complications of breast augmentation surgery can be affected by the patient’s health, implant characteristics, surgical technique, and placement. An implant may be placed above or below the chest muscle or through a dual-plane technique.
Some board-certified plastic surgeons, including Dr. Daniel Maman, almost exclusively use a dual-plane approach, with portions of the implant beneath the muscle and breast tissue. He considers the patient’s anatomy, tissue coverage, goals, and implant characteristics when planning surgery. No technique, however, eliminates every risk.
Infection, Bleeding, Hematoma, and Swelling
An infection may cause increasing redness, warmth, swelling, pain, fever, drainage, or an incision that is not healing properly. Many infections appear during the first several days or weeks, although they can develop later.
A hematoma is a collection of blood near the surgical site. It may cause one breast to become larger, more bruised, swollen, or painful. A seroma is a fluid collection that can also produce swelling, tightness, discomfort, or asymmetry. Worsening symptoms or fluid accumulation that develops long after recovery should be evaluated promptly.
Changes in Breast or Nipple Sensation
Breast augmentation may cause numbness, tingling, heightened sensitivity, or reduced breast and nipple sensation. These changes are often temporary but can persist.
Incision location may affect this risk. An incision around the areola may be more likely to disturb nerves or milk ducts than one within the breast crease. Dr. Maman considers anatomy, implant size, and the patient’s priorities when recommending an incision.
How to Recognize Signs of Breast Augmentation Complications
Patients do not need to diagnose a complication themselves. They should instead watch for symptoms that worsen, affect one breast more than the other, or appear unexpectedly.
Postoperative instructions from the operating surgeon provide a more useful comparison than another patient’s experience because procedures and recovery patterns differ.
Symptoms That May Indicate a Complication
Contact a plastic surgeon about symptoms such as:
- Increasing rather than decreasing pain
- Persistent, worsening, or one-sided swelling
- Redness, warmth, fever, or wound drainage
- An incision that opens or does not heal
- A new lump or fluid collection
- Progressive hardness, tightness, or distortion
- A visible change in implant position
- Sudden loss of breast volume
- New rippling, asymmetry, or contour changes
- Swelling or pain that develops months or years later
Capsular contracture may cause a breast to feel progressively firmer, sit higher, appear distorted, or become painful. Implant malposition may cause the implant to shift downward, upward, inward, or outward.
A saline implant rupture usually causes visible volume loss. Silicone rupture may be difficult to recognize because it can be “silent” and require ultrasound or MRI for detection.
When Post-Surgery Swelling Is a Concern
Swelling should generally improve as recovery progresses. It is more concerning when it suddenly increases, affects one breast significantly more than the other, or accompanies heat, redness, worsening pain, fever, or drainage.
New swelling long after recovery also requires evaluation. In uncommon cases, persistent delayed swelling, pain, or a mass may be associated with breast implant-associated anaplastic large cell lymphoma, or BIA-ALCL. This rare immune-system cancer has primarily been associated with textured implants.
How Common Are Breast Augmentation Complications?
There is no single breast augmentation complication rate for every patient. Studies examine different complications, implants, surgical techniques, and follow-up periods. Some also combine augmentation with reconstruction or revision procedures.
A 2025 clinical review reported capsular contracture rates of 2.4% to 18.9% following primary augmentation in the studies examined. It also cited a hematoma rate of up to 2.8% across breast implant procedures. One 10-year study of a single manufacturer’s silicone implants reported a 7.8% rupture risk 10 years after primary augmentation.
These breast augmentation complications statistics provide context but cannot predict an individual patient’s outcome.
Factors That May Increase the Risk of Complications
Relevant factors can include:
- Smoking or nicotine use
- Certain underlying health conditions
- Implant age, type, surface, and placement
- Limited natural tissue coverage
- Trauma to the breast
- Infection, hematoma, or seroma
- Failure to follow activity restrictions
- Previous breast or revision surgery
- The surgeon’s breast-surgery training and experience
A detailed consultation allows the surgeon to evaluate these factors. Follow-up visits also allow the surgical team to monitor healing and address changes.
What to Do If You Experience Complications After Breast Augmentation
Contact the operating surgeon about unexpected, persistent, or worsening symptoms. Do not massage the breast, change support garments, begin medication, or attempt to drain fluid unless instructed.
Explain when the symptom began, whether it affects one or both breasts, and how it is changing. Photographs may document a visible change but cannot replace an examination or necessary imaging.
How Can I Tell If Something Is Wrong With My Breast Implant?
One symptom can have several possible causes. Firmness may reflect capsular contracture, while swelling may result from a hematoma, seroma, infection, or another condition. Rupture, displacement, and differences in healing can also produce asymmetry.
A plastic surgeon may use an examination, ultrasound, or MRI to evaluate the implant and surrounding tissue. Silicone rupture can be particularly difficult to rule out through appearance or touch alone.
When Should I Call My Plastic Surgeon After Breast Augmentation?
Call when symptoms intensify instead of improving or do not match the recovery expectations provided. Redness, warmth, fever, drainage, rapidly increasing swelling, severe pain, a new mass, or a sudden change in breast shape should be reported promptly.
Seek urgent medical attention for rapidly worsening symptoms or signs of serious infection or bleeding. When uncertain, contact the surgical team rather than waiting for the next appointment.
Scheduling a Consultation
Experience, individualized planning, and follow-up are important before and after breast augmentation. Dr. Daniel Y. Maman is a Harvard fellowship-trained, board-certified plastic surgeon with extensive experience in aesthetic and revisionary breast surgery. He takes time to explain patients’ options and help them feel informed and comfortable.
Individuals considering surgery or seeking an evaluation of possible breast augmentation complications may contact Maman Plastic Surgery to schedule a consultation. Current postoperative patients with urgent concerns should call their plastic surgeon directly.
