How Internal Bra Mesh Is Used in Cosmetic and Reconstructive Surgery

Many women are only learning after the fact that internal mesh was used during their breast surgery—and that it may be the source of their ongoing pain or complications.

Internal bra mesh is typically inserted beneath or around the breast implant to act as a sling, holding the breast in place and reducing pressure on skin and sutures. The technique was used by surgeons as a way to enhance lift, projection, and the longevity of cosmetic procedures such as breast augmentation, lift, reduction, or revision surgeries.

However, lawsuit investigations now highlight that the breast is a far more dynamic environment than the abdomen or groin, where many mesh products were originally used. Inside the breast, mesh can stretch, degrade, migrate, or fail to integrate properly.

As a result, many women have reported severe side effects such as chronic swelling, tissue hardening, infection, and implant failure, often requiring additional surgeries to remove or replace the mesh.

Breast Mesh in Elective Cosmetic Surgery

In elective procedures, internal bra mesh is often used to add structure and support beneath the skin, especially in women with thin tissue or a history of sagging. Surgeons may insert the mesh to reinforce the implant pocket, stabilize results, and prevent complications like “bottoming out,” where the implant drops too low.

These implants have been commonly used during:

• Breast augmentation, to hold the implant in place
• Breast lift (mastopexy), to support the lifted tissue
• Breast reduction, to reshape and stabilize the breast
• Revision surgeries, after prior implants or cosmetic work failed

Although the mesh was intended to integrate with the body, the breast is constantly changing due to hormones, weight, and movement. Over time, many women experienced mesh failure—leading to swelling, hardening, chronic pain, or the need for additional surgeries to remove or replace the material. Lawsuits are now being pursued, alleging that women were not properly warned about these risks from breast mesh.

Mesh Used in Reconstruction After Cancer Surgery

Internal bra mesh has also been widely used in breast reconstruction for cancer survivors, often placed beneath the skin or chest muscle to help shape the new breast and hold an implant or expander in place. In some cases, surgeons used biologic mesh products, called acellular dermal matrices (ADMs), made from processed human or animal tissue and sold under brand names like Strattice, AlloDerm, and FlexHD.

These materials were marketed as natural, body-friendly scaffolds. But when they failed to integrate, the results can lead to:

• Implant loss
• Skin necrosis
• Chronic infections
• Reconstruction collapse

For breast cancer survivors seeking healing and closure, mesh complications have added a painful and unexpected setback. Lawsuits allege that manufacturers knew these materials were not tested or approved for breast reconstruction but pushed them into the market anyway, without proper warnings about the risks.

Why Breast Mesh Fails Inside the Breast

The breast is a complex, constantly moving environment, and mesh materials were never specifically designed for these conditions. Now, women are pursuing lawsuits over the way manufacturers sold these products to plastic surgeons, who used them in breast tissue, despite never receiving FDA approval for that purpose.

Below are several of the reasons outlined in either medical studies or lawsuit investigations that explain why internal mesh products often fail when implanted in the breast.

Delicate and Dynamic Environment

• Constant motion: Daily movement, exercise, and gravity put strain on the mesh and its attachment points.
• Soft, fatty tissue: Unlike firm abdominal muscle, breast tissue offers little structure for the mesh to anchor securely.

Chronic Inflammatory Response

• Foreign material reaction: The body attempts to isolate the mesh, leading to thick scar tissue formation.
• Failed integration: Instead of blending with tissue, mesh can trigger prolonged inflammation that weakens the surrounding area.
• Collagen remodeling issues: The healing process may distort normal tissue architecture, setting the stage for later complications.

Degradation and Migration

• Unpredictable breakdown: Supposedly “absorbable” meshes can degrade unevenly, leaving sharp or stiff fragments behind.
• Loss of stability: Over time, mesh tension changes, allowing it to stretch, curl, or detach from the chest wall.
• Structural collapse: Once the mesh fails, the implant pocket can lose shape or support entirely.

High Risk of Contamination

• Limited blood flow: The internal breast pocket may heal slowly and provide poor immune defense.
• Bacterial adhesion: Even small surface bacteria can form biofilms that resist antibiotics, setting the stage for infection.

Breast Mesh Side Effects and Complications

Adverse event reports submitted to the FDA through its MAUDE database describe a pattern of serious side effects and complications following internal bra mesh implantation, echoing concerns raised in published medical literature and patient accounts.

Women across the country report injuries that often emerge as the mesh degrades, migrates, or contracts inside the breast, leading to chronic pain, cosmetic deformities, infections, and, in many cases, additional surgeries to remove or revise the implant.

Infection and Abscess Formation

Lawsuit investigations are focusing on mesh-related infections that occur when bacteria attach to the surface of the implant and form resistant biofilms, which can be difficult to treat and often lead to removal of both the mesh and the implant.

Symptoms: Women often notice warmth, redness, or swelling around the breast, sometimes accompanied by fluid drainage or fever. Pain may intensify when pressure is applied, and the breast may feel firm or tender to the touch.

Treatment: In most cases, oral or IV antibiotics alone are not enough. Doctors usually must remove the infected mesh, and often the implant, to clear the infection completely. After recovery, reconstructive surgery may be needed to restore shape or symmetry.

Chronic Inflammation

Women have reported chronic inflammation and painful hardening around the implant site, claiming that internal mesh caused excessive scar tissue to form, which distorted breast shape and led to ongoing discomfort that often required revision surgery.

Symptoms: The breast becomes increasingly hard, round, and painful. Some women describe a tight, pulling sensation or visible warping of the implant. Contracture is often graded by severity, from mild firmness to severe distortion and sharp pain.

Treatment: Surgical revision is the primary option. The thickened scar capsule may be released or removed entirely, and the mesh often must be taken out to prevent recurrence. In severe cases, the implant may also need to be replaced or permanently removed.

Seroma and Fluid Buildup

A common side effect reported is seromas, where fluid collects around the implant due to irritation from mesh movement or breakdown. Women say they were forced to undergo multiple draining’s or corrective surgeries after fluid buildup led to pain or infection.

Symptoms: Seromas cause swelling, tenderness, or a sensation of fluid movement inside the breast. The area may feel heavy, sore, or tight. If left untreated, the skin can stretch or become discolored, and infection can develop.

Treatment: Doctors often begin by draining the fluid using a syringe or catheter, but persistent cases may require surgical removal of the mesh and drainage system. Once the area stabilizes, additional reconstruction may be needed.

Mesh Migration and Implant Displacement

One of the most commonly reported complications is mesh loosening or detachment from the chest wall, which may occur when surrounding tissue fails to anchor the implant securely or when absorbable materials break down unevenly over time.

Symptoms: Women may notice the breast appearing lower or uneven compared to the other side. The implant can shift, creating rippling, bulging, or “bottoming out.” In some cases, the breast feels unstable or visibly moves when lying down.

Treatment: Corrective surgery is required to reposition the implant and remove or replace the damaged mesh. Surgeons may reconstruct the pocket using native tissue or another material that provides better long-term support.

Skin Erosion and Tissue Necrosis

Adverse event reports submitted to the FDA through its MAUDE database describe cases where chronic inflammation, infection, or mechanical irritation around internal bra mesh implants was followed by skin breakdown and tissue damage. In some reports, this process allegedly led to erosion of the surrounding tissue, allowing portions of the mesh or implant to become exposed or visible through the skin.

Symptoms: The skin may appear thin, shiny, or darkened in certain areas. Open wounds, drainage, or exposed mesh are clear signs of tissue necrosis and require urgent care. Pain and tenderness typically worsen as tissue damage progresses.

Treatment: Immediate surgical removal of the mesh and affected tissue is necessary. Antibiotics and wound care follow, and reconstructive surgery may be attempted once healing is complete. In severe cases, full implant loss can occur.

Chronic Pain and Nerve Injury

Women have reported scar tissue and inflammation pressing against nerves along the chest wall or underarm, causing persistent pain and sensitivity. In some cases, nerve damage may also occur during mesh removal or revision surgery, leading to long-term discomfort.

Symptoms: Sharp or burning pain, tingling, numbness, or hypersensitivity are common. Some women experience radiating pain toward the arm or shoulder, or lingering soreness that limits daily activity.

Treatment: Early intervention may include anti-inflammatory medication, physical therapy, or nerve blocks. If pain persists, removal of the mesh and surrounding scar tissue may provide relief, though nerve recovery can take months and may not be complete.

Breast Deformity and Implant Loss

One of the most commonly reported reasons for implant replacement surgery is breast deformity. When mesh integrity fails, the internal support structure can collapse, causing the implant to drop, fold, or rupture, often resulting in visible distortion or asymmetry.

Symptoms: The breast may appear flat, uneven, or misshapen. Some patients feel wrinkling or dimpling under the skin, or notice one breast sagging lower than the other. In advanced cases, the implant may completely deflate or shift position.

Treatment: Corrective procedures can include removing the mesh, rebuilding the breast pocket, and replacing the implant. However, outcomes vary depending on how much tissue was damaged. Some patients choose not to pursue further reconstruction after multiple failed surgeries.
