Breast augmentation/enlargement— also known as augmentation mammoplasty — is surgery to increase breast size. It involves placing breast implants under breast tissue or chest muscles.
For some women, breast augmentation is a way to feel more confident. For others, it’s part of rebuilding the breast for various conditions.
If you’re considering breast augmentation, talk to a plastic surgeon. Make sure you understand what surgery involves, including possible risks, complications and follow-up care.

Why it’s done
Breast augmentation might help you:
•Enhance your appearance if you think your breasts are too small or that one is smaller than the other
•Adjust for a reduction in the size of your breasts after pregnancy
•Correct uneven breasts after breast surgery for other conditions
•Improve your self-confidence
How you prepare
You’ll consult with a plastic surgeon about your preferences for size, feel and appearance of your breasts. The surgeon will describe specific types of implants — smooth or textured, round or shaped like a teardrop, saline or silicone — as well as options for surgical techniques.
You might need a baseline mammogram before your surgery. Your doctor might adjust certain medications before the surgery as well. For example, it’s important to avoid aspirin or other medications that can increase bleeding.
If you smoke, your surgeon will ask you to stop smoking for a time before the surgery.
Arrange for someone to drive you home after the surgery and to stay with you for at least the first night.
During the procedure
Breast augmentation requires general anesthesia, in which you’re asleep for the surgery. To insert the breast implant, your surgeon will make a single cut (incision) in one of three places:
•In the crease under your breast (inframammary)
•Under your arm (axillary)
•Around your nipple (periareolar)
After making an incision, the surgeon will separate your breast tissue from the muscles and connective tissue of your chest. This creates a pocket either behind or in front of the outermost muscle of the chest wall (pectoral muscle). The surgeon will insert the implant into this pocket and center it behind your nipple.
Saline implants are inserted empty and then filled with sterile salt water once they’re in place. Silicone implants are pre-filled with silicone gel.
When the implant is in place, the surgeon will close the incision — typically with stitches (sutures) — and bandage it with skin adhesive and surgical tape.
After the procedure
Soreness and swelling are likely for a few weeks after surgery. Bruising is possible, too. Expect scars to fade over time but not disappear completely.
While you’re healing, it might help to wear a compression bandage or sports bra for extra support and positioning of the breast implants. Your surgeon might prescribe pain medication as well.
Follow your surgeon’s instructions about returning to regular activities. If you don’t have a physically demanding job, you might be able to return to work within a few weeks. Avoid strenuous activities — anything that could raise your pulse or blood pressure — for at least two weeks. While you’re healing, remember that your breasts will be sensitive to physical contact or jarring movements.
If your surgeon used sutures that don’t absorb on their own or placed drainage tubes near your breasts, you’ll need a follow-up appointment for removal.
If you notice warmth and redness in your breast or you run a fever, you might have an infection. Contact your surgeon as soon as possible. Also contact your surgeon if you have shortness of breath or chest pain.
Results
Breast augmentation can change the size and shape of your breasts. The surgery might improve your body image and self-esteem. But keep your expectations realistic, and don’t expect perfection.
Also, your breasts will continue to age after augmentation. Weight gain or weight loss might change the way your breasts look, too. If you become dissatisfied with the appearance of your breasts, you might need more surgery to correct these issues.
