Like a cavity, a melanoma may grow for years before producing any significant symptoms.

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.
