For non-metastatic breast cancer or risk-reducing mastectomy. Before surgery, discuss reconstruction or flat closure with every patient, with a plastic or oncoplastic surgeon. Age alone is not a reason to withhold reconstruction.
Prior radiotherapy to the breast or chest wall: more implant complications; own-tissue (autologous) reconstruction is often preferred.
Rapid onset (under 6 months) of redness, swelling or peau d'orange over a third or more of the breast skin, with biopsy-proven invasive carcinoma. Mastitis can look the same.
Trimodality therapy first: neoadjuvant systemic therapy, modified radical mastectomy, then PMRT. No skin-sparing mastectomy, immediate reconstruction or expander. Offer reconstruction after all treatment, 6 to 12 months after RT ends and when the skin has healed. After RT, own-tissue reconstruction has fewer complications than implants.
Ask radiation oncology before surgery. Final pathology can change the answer.
Tell the patient that RT raises complication rates, more with implants than with own tissue. Plan so that reconstruction does not delay or compromise RT.
Both are options. Immediate reconstruction avoids a period without a breast and an extra operation. Decide with the patient: mastectomy type, skin perfusion, comorbidities, breast size and wishes.
Shared decision: body habitus, donor sites, radiotherapy, risk factors and preference.
Fewer complications without prior or planned RT. Tell the patient about BIA-ALCL risk (higher with textured implants): report new swelling, seroma or a lump, even years later. Australia: register in the Australian Breast Device Registry.
Often preferred after prior chest RT or when PMRT is planned (fewer RT complications than implants). Needs a suitable donor site. Abdominal scars or prior abdominal surgery change planning but do not rule it out; previous abdominoplasty usually rules out an abdominal flap (image first if one is considered).
A valid choice. Delayed reconstruction stays possible later.

Applicable Regions
AU: TGA 2019 review of BIA-ALCL: macro-textured and polyurethane-coated breast implants are no longer on the ARTG. Written BIA-ALCL information must be given with every implant and tissue expander. Register implants in the Australian Breast Device Registry.
UK: NHS commissioned service
US: Women's Health and Cancer Rights Act (1998): health plans that cover mastectomy must cover reconstruction.

The Breast Reconstruction Timing After Mastectomy is a management clinical algorithm for Plastic Surgery. It provides a structured decision tree to guide clinical decision-making, based on Ontario Health (Cancer Care Ontario) clinical practice guideline: Postmastectomy Breast Reconstruction in Non-Metastatic Breast Cancer (Zhong T et al, Curr Oncol 2025;32(6):357); NCCN Guidelines Breast Cancer v7.2026.
This algorithm is based on Ontario Health (Cancer Care Ontario) clinical practice guideline: Postmastectomy Breast Reconstruction in Non-Metastatic Breast Cancer (Zhong T et al, Curr Oncol 2025;32(6):357); NCCN Guidelines Breast Cancer v7.2026 (DOI: 10.3390/curroncol32060357).
Known limitations include: Non-metastatic breast cancer only. Metastatic disease, or breast cancer in pregnancy: the breast MDT decides timing.; Timing and type are shared decisions with the breast MDT and the reconstructive surgeon; local access and waiting times vary.; Pre-mastectomy (neoadjuvant) radiotherapy with immediate reconstruction is still under trial and is not covered.. Individual patient factors may require deviation from these recommendations.
