A procedure that aims to increase breast size using prosthetic breast implants .
The implants vary in profile (round - low, moderate, high - or anatomical), depending on the breast shape and size that is required. Implants are filled with silicone or saline within a textured or smooth container.
The implant used depends on the specific needs of the patient, given different physical shapes and the shape, size and consistency sought.

A woman may consider augmentation surgery when the actual breast size is, in her opinion, too small or disproportionate to the rest of her body, or if breasts have become deformed after pregnancy or with ageing.

Implants can be placed behind the mammary gland or behind the pectoral muscle (pectoralis major muscle).  An incision around the areola, the sub-mammarian groove or in the armpit (so that the scar becomes invisible) may be made to implant the prosthesis. Sometimes a drain is located so  secretions which appear after surgery do not collect around the prosthesis.

Smoking should be avoided for at least two or three weeks before and after the surgery.

A small degree of asymmetry is natural and acceptable, but can be improved or corrected.
Over time, ten or twelve years after surgery, there is the possibility, admittedly remote and uncommon, that the body may start rejecting the implant, causing changes in aesthetic look and functionality.  This may require implant replacement.
The quality of the scar depends not only on the technical expertise of the surgical team but also the specific characteristics of the skin.
Patient expectations must take into account that the goal is improvement, not absolute perfection.

After breast augmentation surgery, patients should use a special bra.
A few days after surgery, breasts may be sore, with a feeling of tightness.
Sensitivity at the nipple may be reduced, returning after a few weeks. Bruises and swelling may occur which disappear within two or three weeks.
Dressings and stitches can be removed about one week after surgery and the patient should use a sports bra with front closure for several weeks to help the breasts maintain a balance.
To help reduce the swelling, the patient should sleep on her back with her head resting on two or three pillows for several weeks.
The patient may experience some numbness of the nipple and breast skin, but this will tend to disappear after a few weeks.

Dynamic activity should be avoided for six to eight weeks. For several days (possibly three to five days), the patient should minimise arm and elbow extension and should never raise her arms above the armpits.
This is very important because the repair and healing of tissues will be faster if the patient avoids any activity which may result in injury.
The scars will be stiff and pink for at least six weeks and will disappear within six months to a year.
Any drains are usually removed one to two days after surgery.
