Melanoma can appear on skin not normally exposed to the sun. Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas.

Can it take years for melanoma to spread?

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%.

Can you have melanoma for years and not know?

How long can you have melanoma and not know it? It depends on the type of melanoma.

How do you know if melanoma has spread?

What is the first stage of melanoma?

The earliest stage of melanoma, stage 0, is limited to the outermost skin layer called the epidermis. This is a noninvasive stage, which is also called melanoma “in situ,” meaning “in its original place.” With stage I melanoma, the tumor’s thickness is 1mm or less.

Does melanoma show up in blood work?

Blood tests. Blood tests aren’t used to diagnose melanoma, but some tests may be done before or during treatment, especially for more advanced melanomas. Doctors often test blood for levels of a substance called lactate dehydrogenase (LDH) before treatment.
