Second diagnosis

Hello, I’m new here. I had a melanoma on my jawline two years ago. It was removed. I now have another melanoma in the same place. The first melanoma was removed without a statement of clear margins, but I was not called back for regular checks. Now this second melanoma. I’m thinking everything was not removed tge first time? And, if so, could it have travelled elsewhere? I’m really worried and any sensible thoughts would help. Thank you
