How to Use This Calculator
- Enter patient Age and select Fitzpatrick Skin Type.
- Input Total Mole Count and number of Atypical Moles.
- Toggle Family History, Personal History, and History of Blistering Sunburns.
- Indicate Immunosuppressed status if applicable.
- Review Relative Risk, Estimated Lifetime Risk (%), and the recommended screening interval.
How the result changes with Fitzpatrick Skin Type
| Fitzpatrick Skin Type | Relative Risk | Lifetime Risk |
|---|---|---|
| 1.5 | 3.3 | 8.5% |
| 2.75 | 1.3 | 3.4% |
| 4.25 | 1.3 | 3.4% |
| 5.5 | 1.3 | 3.4% |
What each input means

- Fitzpatrick Skin Type
- 1=always burns … 6=never burns.
- Total Mole Count
- Estimated total common moles.
- Atypical Moles
- Clinically atypical/dysplastic nevi.
- Family History
- First-degree relative with melanoma: 0=no, 1=yes.
- Personal History
- Prior melanoma: 0=no, 1=yes.
- Blistering Sunburns
- Lifetime severe blistering sunburns.
- Immunosuppressed
- 0=no, 1=yes.
What each result means
- Relative Risk
- vs average population (1.0 = average).

- 1=average, 2=moderate, 3=high, 4=very high.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersAge = 45, Fitzpatrick Skin Type = 2, Total Mole Count = 25, Atypical Moles = 0 = 8 input(s) provided
- Calculate Relative RiskRelative Risk = 1.03.3 = 3.3
- Calculate Lifetime RiskLifetime Risk = min(95, baselineRisk * relativeRisk * 100)8.5 = 8.5
