Is this tool a medical diagnosis or a real recurrence probability?

No. This tool produces an educational estimate only. It is not a diagnosis, not a clinical prediction, and not medical advice. Real recurrence-risk assessment is done by a doctor using validated tools such as PREDICT, Oncotype DX, MammaPrint, or the Nottingham Prognostic Index.

Is the 0–100 score a percentage probability?

No. The 0–100 score is an illustrative index built from transparent, hand-picked weights. It has no validated relationship to any real-world probability of recurrence and must never be read as a percentage chance.

Which clinical tools do doctors actually use for recurrence risk?

Commonly used validated approaches include the PREDICT online model, genomic assays such as Oncotype DX and MammaPrint, and clinicopathological indices such as the Nottingham Prognostic Index. Ask your oncology team which is appropriate for your situation.

How is DCIS (ductal carcinoma in situ) handled here?

DCIS is generally reported as stage 0. In this educational model stage 0 contributes zero points, but DCIS has its own distinct clinical considerations, so this tool is especially unsuited as any guide for DCIS management. Discuss DCIS-specific validated approaches with your doctor.

Why did my result come out high?

The result page shows a per-factor breakdown of exactly how many points each factor contributed. Generally, higher stage, higher grade, more involved lymph nodes, larger tumor size, hormone-receptor negativity, and HER2 positivity add points in this illustrative model. The breakdown is educational context, not a clinical explanation.

Does a 'low' result mean there is no risk of recurrence?

No. No category in this tool implies zero risk, and a low illustrative score does not rule out recurrence in the real world. Only your oncology team can assess your actual situation.

How is this different from the breast cancer risk calculator?

This tool is about recurrence after a breast cancer diagnosis — it is for people who have already been diagnosed. The breast cancer risk calculator (breast-cancer-risk) is about the initial risk of developing breast cancer in the first place, and is intended for a general audience without a diagnosis. The two tools answer different questions for different audiences.

What should I discuss with my doctor after seeing this result?

Bring your pathology report and ask about validated recurrence-risk tools such as PREDICT or genomic testing (for example Oncotype DX or MammaPrint where applicable), your treatment plan, and follow-up schedule. This tool's score is not something to base any medical decision on.

Is any of my health data stored or sent anywhere?

No. This tool runs 100% in your browser. Nothing you enter is sent to any server, stored, or tracked. Your inputs stay on your device.

Who is this estimator for?

It is an educational resource for people who want to understand which tumor factors clinicians commonly discuss when talking about recurrence risk. It is not a substitute for professional medical advice, diagnosis, or treatment.

Breast Cancer Recurrence Risk Estimator

An educational score of commonly-discussed tumor factors on an illustrative 0–100 scale — not a clinical prediction.

⚠️ Educational estimate only — not medical advice.

This is not a diagnosis and not a real recurrence probability. The 0–100 score is illustrative, not a percentage.
Validated tools used by doctors include PREDICT, Oncotype DX, and MammaPrint. Only your oncology team can assess your actual risk.

illustrative score out of 100 — not a percentage, not a clinical prediction

⚠️ This number is an educational illustration, not medical advice.

Real recurrence-risk assessment uses validated tools: PREDICT, Oncotype DX, MammaPrint, or the Nottingham Prognostic Index — interpreted by your oncology team.
Please discuss your pathology report and these validated tools with your doctor.

How this score is built (transparent & illustrative)

Six commonly-discussed factors are each given a fixed, hand-picked point value; the total is capped at 100. These weights are illustrative, not derived from any clinical study, and have no predictive validity. Categories: low (below 25), moderate (25–50), high (above 50).
