FAQ
Frequently Asked Questions
No, the vast majority of nevi are benign. However, certain types, like dysplastic nevi, can have a higher risk of developing into melanoma and require monitoring.
'Nevus' is the formal medical term. 'Mole' is the common, everyday word for a melanocytic nevus. In medicine, 'nevus' can also refer to vascular birthmarks, which 'mole' typically does not.
It is pronounced /ˈniːvaɪ/ (NEE-vye).
You should consult a dermatologist if a nevus changes in size, shape, colour, or texture, or if it bleeds, itches, or becomes painful. This is following the ABCDE rule for melanoma detection.
