You are catching this early and that is the key! Keep up the good watch!
My mom has had melanoma at the highest level for over 2 years. The treatements taken to this point have not impacted her quality of life at all.
At this stage you are working to watch for any more signs. You do this with dermotoologest check ups head to foot on a regular basis. Scans by your doctor to "see inside" if there is anything there. Keep the watch up and IF or WHEN something else is found, remember you have options for treatment.
The key is to keep up the watching steps and find anythign early so you have all the options of treatment avaialbe for you.
Best wishes on dealing with melanoma.
