Breast surgery is any surgical procedure that treats disease in the breast, rebuilds the breast after treatment, or changes its size and shape. It’s one of the most common categories of surgery performed in the United States, with well over 300,000 breast augmentations alone carried out each year. The procedures range widely, from removing a small tissue sample for biopsy to full breast reconstruction using tissue from another part of your body.
The Three Main Categories
Breast surgeries fall into three broad groups: cancer-related procedures that remove tumors or at-risk tissue, reconstructive procedures that restore the breast’s shape after cancer treatment, and cosmetic procedures that alter size or appearance by choice. Some surgeries blur these lines. A breast reduction, for example, is sometimes performed for cosmetic reasons and sometimes to relieve chronic back and shoulder pain. Reconstruction after mastectomy is technically elective but closely tied to cancer treatment.
Cancer-Related Breast Surgery
When breast cancer is diagnosed, surgery is almost always part of the treatment plan. The two primary options are lumpectomy and mastectomy, and the choice between them depends on tumor size, location, and personal preference.
A lumpectomy removes only the tumor and a margin of surrounding tissue, preserving most of the breast. It’s sometimes called breast-conserving surgery and is typically followed by radiation therapy to reduce the chance of recurrence. A mastectomy removes the entire breast. Variations include single or double mastectomy, nipple-sparing mastectomy (which preserves the skin envelope and nipple for a more natural look after reconstruction), and prophylactic mastectomy, performed on healthy breasts to lower cancer risk in people with high genetic susceptibility.
Other cancer-related procedures include breast biopsy, where a small tissue sample is removed and examined under a microscope, and axillary lymph node dissection, where lymph nodes under the arm are removed to check whether cancer has spread.
Breast Reconstruction
Reconstruction rebuilds the shape of the breast after mastectomy. It can happen at the same time as the mastectomy (immediate reconstruction) or months to years later (delayed reconstruction). There are two main approaches.
Implant-based reconstruction uses saline or silicone implants to recreate breast volume. A tissue expander is often placed first, gradually stretching the chest skin over several weeks before the final implant is inserted. Surgeons sometimes use a biological mesh material to help support the implant and improve its position.
Autologous reconstruction, also called flap surgery, uses tissue taken from another part of your body, most commonly the lower abdomen, back, or thigh. The tissue is moved to the chest and shaped into a breast mound. This approach avoids implants entirely and can produce a result that feels more like natural breast tissue, though the surgery is longer and recovery involves healing at two separate sites. Some reconstructions combine both methods, using a flap of tissue alongside a smaller implant. Fat grafting, where fat is liposuctioned from one area and injected into the breast, is sometimes used as a finishing touch to smooth out contour irregularities.
Cosmetic Breast Surgery
Cosmetic procedures change breast size, shape, or position without a medical diagnosis driving the decision. The American Society of Plastic Surgeons reported over 306,000 breast augmentations and nearly 77,000 breast reductions in their most recent annual data.
Breast augmentation places implants (saline or silicone) to increase breast size. The implant can be inserted through incisions in the crease under the breast, around the areola, or in the armpit. Breast reduction removes excess tissue, fat, and skin to make the breasts smaller and lighter. It’s one of the procedures with the highest patient satisfaction rates in plastic surgery, particularly for people experiencing neck, back, or shoulder pain from heavy breasts.
A breast lift reshapes and tightens breast tissue without changing overall size. During the procedure, a surgeon repositions the nipple and areola higher on the chest, removes stretched skin, and reshapes the underlying tissue for a firmer contour. It typically takes one to two hours. A lift is often combined with augmentation or reduction when someone wants both a shape change and a size change.
What Recovery Looks Like
Recovery varies significantly depending on the procedure. Minor surgeries like biopsy may only require a day or two of rest, while mastectomy with reconstruction can mean six to eight weeks before returning to work.
For major breast procedures, you’ll generally need to avoid lifting anything heavier than five to ten pounds and keep your arms below shoulder height for about six weeks. Walking regularly is encouraged from the start, but strenuous exercise is off limits during that window. Many people feel fatigued for the first week or two, and your surgeon may modify your return-to-work timeline based on how physically demanding your job is.
If you have a mastectomy or reconstruction, you’ll likely go home with one or more surgical drains. These are small bulbs connected to tubes that collect fluid from the surgical site. You’ll need to empty them two to three times a day, measure the output, and log it. The fluid typically starts out red, shifts to pink, then becomes watery and lighter over the following days. Most drains stay in for one to three weeks. If the drainage suddenly increases, stays bright red, or develops a foul smell with a greenish color, that warrants a call to your surgeon.
Risks and Complications
All breast surgeries carry standard surgical risks: infection, bleeding, and scarring. Infection most commonly shows up within the first week but can develop later. A hematoma, a collection of blood under the skin, sometimes requires drainage with a needle or a return to the operating room.
Implant-specific complications deserve particular attention. Capsular contracture is the most well-known: scar tissue forms around any implant naturally, but in some cases it tightens and hardens, squeezing the implant and causing pain or visible distortion. It’s graded on a four-point scale, from Grade I (soft and natural-feeling) to Grade IV (hard, painful, and visibly distorted). Capsular contracture is more likely to occur after infection or bleeding complications, though it can happen without a clear trigger.
Implant rupture is another possibility. Saline implants deflate noticeably when they leak, while silicone ruptures can be silent and detectable only on imaging. The FDA recommends routine screening for silicone implant rupture. Changes in nipple or breast sensation are common after any breast surgery and may be temporary or permanent.
In rare cases, breast implants have been linked to a type of immune system cancer called breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). The FDA requested a voluntary recall of one manufacturer’s textured implants in 2019 due to this association. More recently, the FDA issued safety communications about reports of squamous cell carcinoma developing in the scar tissue capsule around implants. These cancers are rare, but the FDA now requires boxed warnings on implant labeling and a patient decision checklist to ensure people understand the long-term considerations before choosing implants.
Gender-Affirming Breast Surgery
Breast surgery is also performed as part of gender-affirming care. For transmasculine individuals, “top surgery” is a form of mastectomy that removes breast tissue and reshapes the chest to create a flatter, more traditionally masculine contour. For transfeminine individuals, breast augmentation with implants increases breast size when hormone therapy alone hasn’t produced the desired result. The surgical techniques overlap substantially with those used in cosmetic and reconstructive contexts, though the goals and psychological significance differ.
