- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This only looked back at records of real patients, and tested no new treatment.
The short version
People whose melanoma began at the earliest stage did worse once it spread.
What was studied. Doctors in Spain studied 365 people whose melanoma had spread through the body. They compared how long each person lived, based on the stage of their first melanoma.
What they found. Of the 365 people, 58 started with stage I melanoma, the earliest stage. Their cancer took longer to come back, 52 months. But when it came back, it had spread more widely. They more often had cancer in the brain. Their typical survival was 19.8 months, the shortest of all the groups.
What this means, and what it doesn't
What it could mean: If you had an early melanoma that later spread, close follow up may matter. Checking for cancer in the brain may be part of that. Ask your doctor what scans and checks are right for you.
What it doesn't mean: This does not mean an early melanoma will come back. It is uncommon for stage I melanoma to spread. This study only looked back at past patient records. It did not test any new drug or treatment. It does not predict what will happen to one person, and it is not a cure.
