How much time a melanoma takes to metastasize?

The median time to metastasis for patients with localized disease was 28 months. The timing of appearance of metastases varied minimally; however, times to metastases for distant organs varied greatly. For the first metastatic pathway, more than half of the primary metastases were M1A (57%). read more

Primarily, it depends on the type of melanoma (it can be lentigo maligna melanoma, superficial spreading melanoma, nodular melanoma, or acral lentiginous melanoma), the size and thickness of the nevi/mole that you have, the clinical stage, and other risk factors that you have that may affect the aggressiveness of the lesion. read more
