Symptoms and early signs

The short answer

The earliest sign is usually firmness rather than appearance, and it is frequently on one side only. People often notice it lying down, when the implant no longer settles to the side the way it used to. Tightness, a change in shape, and pain follow later if it progresses. Pain is a feature of advanced contracture, not an early warning.

Early signs

These are the changes people describe first, roughly in the order they tend to appear.

• The breast feels firmer than it used to. Not hard, just less soft. This is the single most common first sign, and comparing against your own memory of a few months ago matters more than comparing against the other side.
• It stops moving the way it did. Lying on your back, an implant in a soft capsule settles outward. A tightening capsule holds it in place.
• One side changes and the other does not. Contracture is frequently one-sided, which is why asymmetry that is new is worth paying attention to.
• A vague ache after activity, or a feeling of tightness at the end of the day that was not there before.
• The upper edge of the implant becomes more noticeable as it is pushed upward.

How symptoms progress

Contracture is a spectrum rather than an on-off event. Surgeons describe it in four grades, and the symptoms line up with them:

• Soft and natural-looking. No symptoms. This is where most implants stay.
• Slightly firm, still looks normal. You can feel a change; nobody else can see one.
• Firm, and the shape has visibly changed. Rounder, higher, more obviously an implant.
• Hard, distorted and painful. Pain at rest, not just with pressure or movement.

Our page on the Baker grades sets these out properly, including why the grade usually determines whether surgery is offered.

What it is not

Not every change in a breast with implants is contracture, and some alternatives matter more.

• Normal post-surgical firmness. In the first months after augmentation breasts are firm and settle over time. Firmness that is decreasing is expected; firmness that is increasing is not.
• Rupture. A change in shape or size can also indicate implant rupture, which is often silent with silicone. See implications.
• Fluid collection or swelling. Late swelling around an implant is the presentation associated with BIA-ALCL and should be assessed rather than watched.
• Ordinary breast tissue changes with weight, hormones and age.

Only an examination, usually with imaging, distinguishes these. That is the argument for being seen rather than reading further.

When to be seen promptly

Contracture itself is not an emergency and usually develops slowly. These changes are different and warrant a prompt appointment rather than a wait-and-see:

• Sudden swelling, particularly on one side and particularly years after surgery
• Fever, spreading redness, or heat over the breast
• A new lump in the breast or armpit
• Pain that is worsening rather than fluctuating
• Any change in a breast that has previously had radiotherapy

Our patient safety page covers this in full, including how to report a device problem to the regulator.

What to do if you think you have it

Book an appointment with a plastic surgeon rather than trying to grade yourself. Bring your implant records if you have them — manufacturer, model and date — because texture type and age both matter to the assessment. If you no longer have those records, the patient safety page explains how to request them.

Firmness alone, with no pain and no visible change, does not automatically mean surgery. Plenty of people live with mild contracture indefinitely and choose to do nothing, which is a legitimate decision rather than a delay.
