The fourth type of melanoma is nodular melanoma which STARTS in the vertical growth phase and can metastasize from the outset. ...Read more

Very much so: It's the distribution of the abnormal cells in relationship to the remaining normal structures. I trained under one of the premiere surgical pathologists of his generation and even then, he would never sign out a melanoma without a second pathologist. ...Read more

If somebody has nodular melanomas or 6 or so years, will it visibly continue to grow in size?

Yes: Melanoma is a fairly aggressive malignancy with a significant history of metastasis a much more problematic issue than local growth. No one should have a melanoma left untreated for a 6 year time frame.

How quickly does nodular melanoma spread?

How quickly does nodular melanoma spread?

Can Spread Quickly: Nodular melanomas tend to grow up as a nodule, and down into the skin. With melanomas, the deeper it is into the skin, the more likely it is to spread. So ask your doctor the depth of penetration in millimeters or the clarks level. Prognosis depends on the depth of penetration, and not the type of melanoma. ...Read more
