During breast reconstruction, surgeons aim to match the size and shape of the reconstructed breast to your other breast. This is not always possible. They may suggest you have an operation on your other breast so they match.
This is usually done as a second operation some months later. But sometimes it is done at the same time as mastectomy and breast reconstruction.
This can be done if your reconstructed breast is larger than your other breast and you prefer the larger breast. Your natural breast can be made bigger using a silicone implant. This can sometimes be combined with a breast lift.
