Breast augmentation is surgery to increase breast size, either by placing implants beneath breast tissue or chest muscle, or by transferring fat from another part of the body. It is one of the most common cosmetic procedures performed today, chosen by people who want larger breasts, more symmetrical breasts, or restoration of volume lost after pregnancy or significant weight loss. The average surgeon’s fee runs about $4,875 for implant-based augmentation and $5,719 for fat grafting, though total costs are higher once you factor in anesthesia, facility fees, and follow-up care.
How Implant Surgery Works
During the procedure, a surgeon creates a pocket either behind the breast tissue (subglandular placement) or behind the chest muscle (submuscular placement). An implant is then inserted through a small incision, and the tissue is closed around it. The whole operation typically takes one to two hours under general anesthesia.
Where the surgeon places the implant affects the look and potential trade-offs. Going behind the muscle does a better job of hiding visible rippling along the upper part of the breast, which makes it a popular choice for people with thinner breast tissue. The downside is that the muscle can pull on the implant over time. One long-term study found a 94% rate of upward implant migration at seven-year follow-up when implants were placed behind the muscle. Placement in front of the muscle avoids those muscle-related distortions but can make the implant easier to feel or see, especially in people without much natural breast tissue. Capsular contracture, where the scar tissue around the implant hardens uncomfortably, can happen with either placement.
Incision Locations
Surgeons generally use one of three incision sites. The inframammary incision sits in the crease beneath the breast, hidden by the natural fold. The periareolar incision runs along the border between the darker areola skin and the lighter breast skin, creating a scar that’s difficult to see once healed. It also gives the surgeon direct visibility inside the pocket during surgery. The transaxillary incision is made in the armpit, keeping any scar off the breast entirely. Your anatomy, implant type, and personal preference all play into which option makes the most sense.
Saline vs. Silicone Implants
Both types have an outer shell made of silicone. The difference is what’s inside. Saline implants are filled with sterile saltwater after insertion, which means the surgeon can fine-tune the volume during the procedure. If a saline implant ruptures, the saltwater absorbs harmlessly into the body and the deflation is immediately obvious.
Silicone implants come pre-filled with a cohesive silicone gel that most people find looks and feels closer to natural breast tissue. The trade-off is that a silicone rupture can be “silent,” meaning neither you nor your doctor may notice it without imaging. The FDA recommends periodic MRI scans or ultrasounds to screen for silent ruptures for as long as you have silicone implants. Saline implants are available to anyone 18 and older, while silicone implants require you to be at least 22 for cosmetic augmentation (though they’re available at any age for breast reconstruction after mastectomy).
Fat Transfer as an Alternative
For people who want a modest size increase without implants, fat grafting is an option. A surgeon harvests fat through liposuction from areas like the abdomen or thighs, processes it, then injects it into the breast in thin layers from deep tissue up to just beneath the skin. The fat is deposited in fine, noodle-like strands so it can establish a blood supply and survive in its new location.
The volume increase is more limited than what implants can achieve. In a study of 105 cases, surgeons grafted an average of 205 mL of fat per breast per session, roughly equivalent to one cup size. When less than 150 mL was transferred, results were often too subtle to notice. Fat transfer also isn’t a great fit for thinner patients who simply don’t have enough donor fat to harvest. About 16% of thin patients in that same study saw no meaningful cosmetic improvement for exactly this reason.
Recovery Timeline
The first week is the most restrictive. You can expect soreness, swelling, and tightness across the chest. During this period, lifting anything heavier than a gallon of milk is off-limits. Most surgeons send you home the same day with a supportive surgical bra.
By weeks two to three, many people with desk jobs feel ready to return to work, as long as the job doesn’t involve physical strain. You’ll still need to avoid lifting more than about 10 pounds. Weeks four through six gradually open the door to more normal activity, though heavy exercise and lifting remain restricted until your surgeon clears you.
Full recovery, meaning a return to all normal activities, takes about six to eight weeks. But what you see at that point isn’t quite the finished product. Implants sit higher on the chest initially and settle into a more natural position over the following months. Most of that settling happens by six months, and by one year, what you see in the mirror is your final result.
Risks and Complications
Like any surgery, breast augmentation carries risks of infection, bleeding, changes in nipple sensation, and scarring. The most common implant-specific complication is capsular contracture, where the natural scar tissue that forms around every implant tightens and hardens, sometimes causing discomfort or a visibly distorted shape.
A rarer but serious concern is breast implant-associated anaplastic large cell lymphoma, or BIA-ALCL. The World Health Organization recognized it in 2016 as a type of immune system cancer that can develop around breast implants. The risk is considered low for any individual, but it is higher with textured-surface implants compared to smooth ones. Symptoms include persistent swelling, a lump, or pain around the implant that develops well after the initial recovery period. When caught early, it is usually treated successfully by removing the implant and surrounding scar tissue.
Some patients also report a cluster of symptoms they call “breast implant illness,” including chronic fatigue, joint and muscle pain, and difficulty concentrating. These symptoms don’t yet fit neatly into a recognized diagnosis, but some people report improvement after having their implants removed.
Long-Term Expectations
Breast implants are not lifetime devices. The longer you have them, the more likely you’ll eventually need a reoperation, whether to address a complication, replace an aging implant, or remove them altogether. If you do have implants removed without replacement, your natural breast tissue may look different than it did before surgery, with possible dimpling, wrinkling, or tissue loss.
Silicone implants require ongoing monitoring. The FDA’s current guidance, updated in December 2023, recommends regular screening with MRI or ultrasound to check for silent ruptures even if you have no symptoms. These imaging costs may not be covered by insurance. Cosmetic breast augmentation itself is almost never covered by insurance, and that includes the cost of future surgeries to address complications or replace implants down the line.
