In breast-conserving surgery the tumour and the healthy tissue around it are removed, and the breast is largely preserved. In early-stage disease and suitable patients, long-term survival is similar to mastectomy.
The operation
The tumour is marked using imaging (with a guide wire or marker if needed) and removed. The tissue is examined in pathology; if the margins are clear no further operation is needed. Many patients go home the next day.
Radiotherapy
When the breast is conserved, radiotherapy to the remaining breast tissue is standard. It markedly reduces the risk of local recurrence. Radiotherapy does not cause hair loss, and afterwards you do not pass radiation on to those around you.
After surgery
- Wear the bra you are given continuously for the first week.
- If you have no drain, you can shower after 48 hours.
- Shoulder exercises are started as your physiotherapist advises.
Risks and points to be aware of
- Bleeding, infection or fluid collection at the surgical site (seroma) may occur.
- Depending on the amount of tissue removed, there may be a slight difference in breast size or shape.
- If the margin is not clear on pathology, a further operation in the same area may be needed.
Follow-up and next steps
The pathology result determines the need for radiotherapy and medication. After that, follow-up continues with regular examinations and yearly imaging.

Frequently asked questions
How many days will I stay in hospital after breast-conserving surgery?
Most patients stay one night and are discharged the next morning; if overall health allows, none at all.
Who cannot have breast-conserving surgery?
Mastectomy is preferred when there are several foci far apart in the breast, radiotherapy cannot be given, or the tumour is very large relative to the breast.
