More worrisome are so-called atypical moles. They often appear during puberty but can pop up throughout life.Does melanoma blanch when pressed?

Sometimes, melanomas come back as 'clusters' of melanomas. The clusters are near where the original melanoma (primary) first started. Doctors sometimes call these satellites or in-transit metastases. The most common place for melanoma cells to spread is to the lymph nodes closest to the melanoma.What is considered a thin melanoma?
Thin melanomas, which up until this point were defined as those with < 1mm Breslow depth, account for approximately 70% of new cases and approximately 25% of melanoma deaths (Hieken et al., 2015) despite having an excellent prognosis with an observed 12-year survival of approximately 85% (Maurichi et al., 2014).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. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade.
