Is the mole oval/round or is it an odd shape? If divided in half, is the mole a mirror image of itself in both halves?
Is the outline smooth or ragged/blurred/notched?
Is the colour of the mole even all the way through? Does the mole contain shades of black/dark brown/grey/blue/white/red in whole or part?
Is the mole larger than the others or atypical in appearance? Has the mole grown?
Is the mole changing over time in size, shape or colour? Is it becoming raised?
Not all of them will be malignant melanomas but these criteria can help in selecting suspicious lesions.
For elevation you need evolution – change over time – so this will not mean that all raised moles will need referral if they do not change.
