Can a mole morph into melanoma, or does it have to start out as a melanoma?

In brief: Moles can "morph"

Moles can change into melanomas, or they can arise out of sun damaged skin.
People with many moles on their body can benefit from regular visits to their dermatologist for regular surveillance and early diagnosis of melanoma or other skin cancer.

In brief: Moles can change

Longstanding moles appear to be able to change into melanomas, although as you point out melanoma may also occur at a site without a preceding mole.

In brief: Probably both ways

The exact cause of melanoma is uncertain.
Sun exposure increases the risk of melanoma, due to uv radiation damaging the dna in cells (causing mutations). In this case, a melanoma can start out as a mutated cell, without having been a mole. People with lots of moles have higher risk of melanoma. In that case, some cells in moles may mutate and "morph" into a melanoma.
