After a previous melanoma diagnosis, a new spot can cause a lot of anxiety.
However, a second melanoma does not automatically mean that the first melanoma has recurred or metastasized.
A New Melanoma
A new melanoma can develop in a different location on the skin.
Doctors call this a second primary melanoma.
This new melanoma is separate from the first. It is examined separately and receives its own assessment and staging.
If the Previous Melanoma Returns
A new spot can also consist of cells from the previous melanoma. In that case, the melanoma has recurred.
This can happen, for example:
– at or near the site where the first melanoma was located
– in a nearby lymph node
– in another part of the body
Where the melanoma cells are found helps doctors determine what is happening and what follow-up is needed.
How Do Doctors Know What It Is?
From the outside, it is usually not possible to tell whether it is a new melanoma or a recurrence of the previous melanoma.
Therefore, the spot is examined. Often, the abnormality is removed, or a tissue sample is examined under a microscope.
Doctors compare the new findings with previous data. Sometimes additional tests are needed to gain more clarity.
What is especially important to know?
A new melanoma and the recurrence of a previous melanoma are two different situations.
A new melanoma receives its own assessment. If the previous melanoma has recurred, doctors re-evaluate where the melanoma cells were found and what that means for the follow-up.
Therefore, it is important to have any new or changing spot assessed after a previous melanoma diagnosis.
Is anything in this explanation still unclear?
