Mucous membranes - includes the mouth, nose, external eyes, and genital skin
Source of Melanomas on the Skin

Where melanoma can start:
In a new mole that develops in adulthood.
In a pre-existing mole.
A mole with hair growing from it:
Small hairy moles are no more likely to develop melanoma than a similar-sized mole without hair.
Likelihood of developing melanoma:
1 in 3000 - The chance of melanoma developing from a normal mole.
1 in 100 - The chance of melanoma developing from an atypical mole.
