Breast augmentation is a surgical procedure that uses implants to increase breast size, alter breast shape or improve breast symmetry. It may be chosen for cosmetic reasons or to restore breast volume following changes such as pregnancy, weight loss or developmental differences.

Breast implants are available in different sizes, shapes and materials, and the choice depends on factors including the individual's anatomy, desired result and amount of existing breast tissue. The position of the implant and the surgical approach are also considered during the consultation.

What types of breast implants are available?

Breast implants are primarily filled with silicone gel or saline, although silicone implants are commonly used in the UK. Silicone implants generally provide a more natural feel, while saline implants deflate if they rupture and the saline is absorbed by the body.

Implants also vary in shape, size and surface characteristics. The most appropriate implant depends on the individual's breast anatomy and desired outcome rather than simply selecting a particular size.

What happens during breast augmentation surgery?

Breast augmentation involves placing an implant either behind the breast tissue or behind the chest muscle through an incision. The operation is usually performed under general anaesthesia and commonly takes around 60 to 90 minutes.

The surgical technique and implant position are selected according to the individual's anatomy, the amount of existing breast tissue and the intended result. Careful planning is important because factors such as implant size and position can influence the appearance and feel of the breasts.

What are the risks of breast implants?

Breast augmentation is generally considered safe when appropriately planned, but it is major surgery and complications can occur.

Potential problems include:

Capsular contracture: scar tissue around the implant becomes tight, causing firmness or changes in shape.
Implant rupture: the outer shell of an implant can tear, sometimes without noticeable symptoms.
Changes in sensation: the nipples or breasts may become more or less sensitive, temporarily or permanently.
Infection and bleeding: these are recognised surgical complications and may require additional treatment.
Rippling or asymmetry: the implant may become visible, develop folds or contribute to differences between the breasts.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare type of lymphoma associated with breast implants. It is not breast cancer and most commonly develops in the scar tissue or fluid surrounding an implant. Persistent swelling, a lump or pain around an implant should therefore be assessed.

How long do breast implants last?

Breast implants are not lifetime devices, so further surgery may eventually be required. There is no fixed lifespan for an implant, and the likelihood of complications generally increases the longer an implant remains in place.

This does not mean that implants routinely need to be replaced after a specific number of years. Decisions about monitoring, removal or replacement depend on the individual's circumstances and whether complications or changes have developed.

What is recovery like after breast augmentation?

Most people can return to light activities relatively soon after surgery, but complete recovery takes several weeks. The NHS advises that many people need around one to two weeks away from work and should avoid heavy lifting or strenuous exercise for at least a month.

Following the surgical team's advice on wound care, activity and follow-up appointments can help support recovery. The breasts can continue to change in appearance as swelling settles and the tissues adapt to the implants.

What should you consider before having breast implants?

A consultation should cover your expectations, medical history, breast anatomy, implant type and size, surgical technique, potential complications and the possibility of future surgery. It is also important to discuss how implants may affect breast screening and what follow-up will be required.

Practical considerations include:

Check that your surgeon is appropriately qualified and registered.
Discuss the advantages and limitations of different implant types and positions.
Ask about the expected recovery period and potential complications.
Keep records of the implant manufacturer, model and other relevant details.
Continue recommended breast screening after having implants.
