🎀 Breast Nodule Smart Manager · Assessment, Follow-up & Treatment Decision
This tool maps the BI-RADS category to malignancy probability and follow-up/biopsy triage, then after diagnosis gives surgery, axillary management, and subtype-based systemic and radiotherapy principles.
Clinical takeaway
Breast conservation with whole-breast radiotherapy is survival-equivalent to mastectomy when eligibility criteria are met. (original synthesis · not guideline verbatim)

When to use
Use to triage imaging findings (1–2 routine, 3 short-term follow-up, 4–5 biopsy, 6 diagnosed) and, once a subtype is known, to outline treatment principles.
How it works
BI-RADS category → malignancy probability and biopsy decision. Diagnosed → breast-conserving + RT vs mastectomy, SLNB (Z0011/AMAROS) vs dissection, and subtype-driven systemic therapy (endocrine/anti-HER2/chemo ± immunotherapy).
Key points
- Breast conservation with whole-breast radiotherapy is survival-equivalent to mastectomy when eligibility criteria are met. (original synthesis · not guideline verbatim)
- Larger HER2+ or triple-negative tumors, or node-positive disease, favor neoadjuvant therapy before surgery.
- BI-RADS is an imaging probability, not a diagnosis — biopsy pathology remains the gold standard.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| BI-RADS category (ultrasound/mammography) | 0 incomplete assessment |
|---|---|
| Maximum nodule diameter | 15 mm |
| Molecular subtype (if diagnosed) | Undiagnosed/unknown |
| Tumor stage cT (if diagnosed) | Unknown |
| Regional nodes cN (if diagnosed) | Unknown |
→ConclusionBI-RADS 0 (incomplete assessment) · short-term follow-up
- (1) Assessment & follow-up：BI-RADS 0 (incomplete assessment) (malignancy probability pending). Needs additional imaging (add mammography/ultrasound/MRI if needed or compare with prior films) before grading; cannot be managed on this basis.
- Note：If malignancy is already biopsy-confirmed, selecting a molecular subtype and stage can continue to give surgical and radiotherapy/chemotherapy principles.

→ConclusionBI-RADS 6 (biopsy-proven malignancy) · treatment decision
- (1) Assessment & follow-up：BI-RADS 6 (biopsy-proven malignancy) (malignancy probability diagnosed). Pathology confirmed, proceed to staging and treatment.
- (2) Surgery：Local: if eligible (unifocal, suitable tumor/breast ratio, negative margins achievable, no radiotherapy contraindication) breast-conserving surgery + whole-breast radiotherapy preferred (survival-equivalent to mastectomy); otherwise mastectomy ± reconstruction. Axilla: cN0 sentinel lymph-node biopsy (SLNB), low-burden sentinel-positive may avoid axillary dissection per Z0011/AMAROS or substitute axillary radiotherapy; cN+/multiple positive sentinels → axillary lymph-node dissection. This case has a larger tumor or positive nodes and is HER2+/triple-negative → neoadjuvant therapy first, then surgery (downstaging, enabling breast conservation and pCR assessment).
- (3) Radiotherapy/chemotherapy & systemic principles：Triple-negative (TNBC): chemotherapy-based (anthracycline + taxane ± platinum); stage II–III neoadjuvant combined with pembrolizumab (KEYNOTE-522); olaparib for BRCA mutation. Radiotherapy: whole-breast radiotherapy after breast conservation (often hypofractionated); after mastectomy, T3–4 or node-positive need chest-wall + regional nodal radiotherapy.
