Can melanoma lay dormant for years?

These studies show that in both uveal and cutaneous disseminated melanoma, cells can remain dormant for longer than a decade, and when they emerge from dormancy they almost invariably are resistant to therapy and fatal.

Can melanoma grow for years?

The lesion can grow slowly for 5 to 15 years in the in situ form before becoming invasive. The exact percentage of lentigo maligna lesions that progress to invasive lentigo maligna melanoma is unknown but is estimated to be less than 30% to 50%.
