How do we compare?

When having your skin checked, it is always nice to know that you are in good hands.

A good measure of accuracy is how many lesions are excised to find a melanoma. Ideally, the less moles that need to be unnecessarily cut out, the better!

How we compare:

Healthcare ProfessionalLesions excised vs melanoma found
MoleMap by Dermatologists4:1 (i) ie. excise four to find one
GP20:1(ii)
Dermatologist12:1(iii)

Another useful measure is sensitivity. Analysis of our database indicates that our sensitivity exceeds 98.9%. What does this mean? Sensitivity measures our accuracy in correctly identifying melanomas. As a comparison, average sensitivities:

Healthcare ProfessionalSensitivity
MoleMap by Dermatologists98.9% (i)
GP29% (ii)
Skin Cancer Clinic (GP led)60% (ii)
Dermatologists80% (iii)
