What your chest looks like in the first days after mastectomy

In the first days after a mastectomy without reconstruction, the chest on the operated side is usually flatter than you may imagine, with a scar running across it, often from near the breastbone towards the armpit. The scar is normally covered by a dressing or clear film, and one or two thin drain tubes may come out through small openings below it. The skin around the scar can look swollen, puffy or slightly uneven, and there may be bruising in shades of purple, yellow or green that spreads down the side of the chest. Some women notice small folds of extra skin at the ends of the scar, especially towards the armpit. The skin often feels numb or strange to touch, and the chest may feel tight. These early appearances change a great deal over the following weeks as swelling settles, bruising fades and the scar flattens and softens. Most women find the chest looks noticeably calmer by the time they see the surgeon for results. Looking for the first time is a very personal moment. Some women want to look straight away in hospital with a nurse beside them, while others wait until they are at home or ask a partner to look first. There is no right way. What matters is knowing which changes are expected and which signs mean you should contact your team.

A flat scar is normal

Most scars run across the chest and are covered by a dressing at first.

Swelling and bruising settle

The chest often looks puffier and more bruised in week one than it will later.

Look when you are ready

A nurse can be with you the first time if you wish.

The first view can be harder or easier than you expect, and both reactions are normal.

It may feel like a shock

Even well-prepared women can feel upset, numb or tearful. These feelings often soften as the chest heals and becomes familiar.

The early look is not the final look

Swelling, bruising and puckering change over months. The scar keeps flattening and fading for a year or more.

Some unevenness may remain

Not every chest ends perfectly flat. Small revisions can smooth leftover skin later if it bothers you.

What this page cannot tell you

It cannot judge your wound. If something looks different from what you were told, ask your nurse to check.

Healing follows a broad pattern, though every body is different.

First two weeks

Dressings are changed or removed, drains usually come out and bruising begins to fade.

Weeks three to six

Swelling reduces and the scar may feel firm or lumpy along its length. A soft bra or camisole with a light prosthesis may feel comfortable.

Months two to twelve

The scar slowly turns from pink or dark to paler and flatter. Numb areas may partly regain feeling, sometimes with odd tingles as nerves recover. Radiotherapy, if given, can darken and tighten the skin for a time.
