Breast Augmentation: Implants, Risks, and What to Expect
Key takeaways
- Breast augmentation uses implants (silicone or saline) placed over or under the chest muscle, through one of a few small incisions, under general anaesthetic.
- Implants are not lifetime devices: many people need further surgery over the years, so plan for the likelihood of revision.
- The real risks include capsular contracture, rupture, changes in sensation, and the rare BIA-ALCL, plus the debated breast implant illness.
- Most people are back to desk work within about a week, with final results settling over 3 to 6 months.
Breast augmentation enlarges or reshapes the breasts using implants, placed over or under the chest muscle through a small incision, under general anaesthetic. It is one of the most common cosmetic operations in the world, and also one people agonise over. This is the honest overview I wish I’d had; the decision, the cost, and recovery each have their own deeper article.
I thought about it for years before going ahead. The thing that helped most was understanding the real choices and the real risks before I sat in a consultation, so here they are.
What it involves
You and your surgeon decide three things: the implant (silicone gel or saline), the placement (over the muscle, or partly under it), and the size and profile. The implant goes in through a small incision, usually in the crease under the breast, around the nipple, or in the armpit. The operation takes about 1 to 2 hours and is often a day case.
Choosing implants and size
- Silicone vs saline: silicone gel feels more like natural tissue and is the most common choice; saline is filled with sterile salt water. See breast implant types.
- Size is measured in volume (cc) and profile (how far it projects), chosen for your frame and tissue, not a bra cup size alone. Going as big as possible is a common regret; choosing a size is about proportion.
The one fact to hold onto
Implants are not lifetime devices. They have no fixed expiry, but many people need further surgery over the years, for rupture, capsular contracture, or simply wanting a change. Plan for the likelihood of revision down the line, financially and emotionally.
The risks, honestly
A good surgeon will not gloss over these, and neither will I:
- Capsular contracture, scar tissue tightening around the implant, the most common complication
- Rupture or deflation, malposition, asymmetry, and rippling
- Changes to nipple or breast sensation, sometimes permanent
- Infection and bleeding
- BIA-ALCL, a rare cancer of the immune system linked mainly to textured implants
- Breast implant illness, a range of systemic symptoms some people report; not fully understood, and acknowledged by the FDA as reported
Surgery can also affect breastfeeding and mammogram imaging. None of this means you should not do it; it means you should go in fully informed.
The surgery and recovery
It is done under general anaesthetic, usually as a day case or one overnight stay. Most people are back to desk work in about 3 to 7 days and avoid heavy lifting and exercise for 4 to 6 weeks. Implants settle and “drop and fluff” over weeks, with final results at about 3 to 6 months. The full picture is in recovery.
Is it right for you?
That is a personal decision, made without pressure and with a qualified surgeon. Start with whether you are a candidate, what it costs, and an honest look at the risks.

Frequently asked questions
How does breast augmentation work?
A surgeon places an implant, either silicone gel or saline, into a pocket made either over the chest muscle (subglandular) or partly under it (submuscular or dual-plane), through a small incision usually in the breast crease, around the nipple, or in the armpit. It is done under general anaesthetic and takes about 1 to 2 hours, often as a day case. You choose the fill, the placement, and the size with your surgeon based on your body and goals.
How long do breast implants last?
Implants are not lifetime devices. They do not have a fixed expiry, but many people need further surgery over the years for reasons such as rupture, capsular contracture, or simply wanting a change, and reoperation is common over time. It is sensible to plan, financially and practically, for the likelihood of revision or replacement surgery at some point.
What are the risks of breast augmentation?
The main risks include capsular contracture (scar tissue tightening around the implant), implant rupture or deflation, changes to nipple or breast sensation that can be permanent, infection, bleeding, asymmetry, and rippling. There is also a rare cancer of the immune system, BIA-ALCL, linked mainly to textured implants, and a range of reported systemic symptoms some people associate with implants, known as breast implant illness. A good surgeon will discuss all of these honestly.
Is breast augmentation painful?
There is real discomfort in the first few days, often described as tightness, soreness, and a heavy feeling, especially with implants placed under the muscle. It is well managed with prescribed pain relief and eases noticeably within a week or so. I found the first 48 hours the hardest, and much easier than I had feared after that.
How long does it take to recover from breast augmentation?
Most people return to desk work within about 3 to 7 days and avoid heavy lifting and exercise for around 4 to 6 weeks. Swelling settles over weeks, the implants 'drop and fluff' into a more natural position, and final results settle over about 3 to 6 months, with scars maturing for up to a year.
