Breast cancer surgery ranges from breast-conserving surgery (removing only the lump) to mastectomy (removing the whole breast), together with management of the lymph nodes. The surgeon chooses the approach based on the size and location of the tumour, the cancer subtype, and the patient's wishes. The goal is to remove the cancer completely while preserving appearance and arm function as much as possible. This guide brings every surgical technique together in one place.
What types of breast cancer surgery are there?
The main options are breast-conserving surgery with radiation, and mastectomy. In suitable patients, both approaches give similar survival outcomes.
Aesthetic-preserving techniques (oncoplastic / nipple-sparing)
These help the breast look natural after surgery, including oncoplastic and nipple-sparing approaches with intraoperative radiation. (Detailed English articles for these techniques are in preparation.)
Lymph node management
Sentinel lymph node biopsy reduces unnecessary node removal and lowers the risk of arm swelling (lymphoedema).
Precise localisation and minimally invasive options
For non-palpable lesions we use Scout Radar localisation, and vacuum-assisted breast lump surgery (VABB) for small lesions.
Radiation during surgery (IORT)
At Namarak, radiation can be delivered during the operation. Read more in the breast cancer treatment guide and see where the journey begins in screening & diagnosis.
Frequently asked questions about breast cancer surgery (FAQ)
What types of breast cancer surgery are there?
Mainly breast-conserving surgery (removing the lump, followed by radiation) and mastectomy (removing the whole breast), along with lymph node management.
How do I choose between lumpectomy and mastectomy?
It depends on the size and number of tumours, location, subtype, and patient preference. In suitable patients, survival outcomes are similar.
Do I need radiation after surgery?
Breast-conserving surgery usually requires radiation to reduce recurrence. Namarak offers IORT, delivered during the operation.
Will my arm swell after lymph node surgery?
Sentinel lymph node biopsy greatly reduces unnecessary removal and the risk of arm swelling (lymphoedema).
How long is recovery after surgery?
It depends on the type of surgery. Most patients recover quickly; the team gives individual advice on wound care and arm movement.
What makes surgery at Namarak Hospital special?
Scout Radar, IORT (Intrabeam), oncoplastic techniques, and a dedicated multidisciplinary breast-surgery team.
