- Enter Age at First Birth
Then click Calculate.
The tool will instantly display:
- 10-Year Risk Percentage
- Lifetime Risk Percentage
- Risk Level (Low / Moderate / High)
🟨 Step 2: Hormone Risk Assessment
- Enter number of years of Hormone Therapy (if any)
- Enter Menopause Age
Click Calculate to get adjusted hormonal risk.
🟩 Step 3: Family & Genetic Risk
- Enter number of 1st-degree relatives with breast cancer
- Enter Genetic mutation risk percentage (if known)
Click Calculate to view family-based risk score.
🔁 Step 4: Review and Share Results
After calculation, you can:
- View detailed risk results
- Copy results for records
- Share results with a doctor or family
- Reset for a new calculation
📊 How the Risk Calculation Works
The calculator uses a simplified risk estimation model inspired by the Tyrer-Cuzick approach. It evaluates:
- Age-related risk increase
- Body weight (BMI influence)
- Early menstruation impact
- Late childbirth risk factor
- Hormone therapy influence
- Menopause timing
- Family cancer history
- Genetic predisposition
Each factor adds or adjusts a base risk score, producing a percentage estimate.
🧪 Practical Example 1: Basic Risk Scenario
User Input:
- Age: 45
- BMI: 32
- First Period Age: 11
- First Birth Age: 31
Result:
- 10-Year Risk: ~4.4%
- Lifetime Risk: ~9–12%
- Risk Level: Moderate
Interpretation:
Higher BMI and later childbirth slightly increase risk, placing the user in a moderate category.
🧬 Practical Example 2: Family & Genetic Risk
User Input:
- 2 relatives with breast cancer
- Genetic mutation risk: 40%
Result:
- Family Risk Score: Elevated (~6–8%)
Interpretation:
A strong family history and genetic risk significantly increase overall risk score.
