Melanoma Insitu removed, now more biopsies 3 months post op

Returned last night from my 3 month check up after a large incision to remove melanoma in-situ from my chest. I am 54 and from the baby oil era. They found 2 other suspicious spots on my arm and calf that they want to biopsy. I am not worried, but I am... does that make sense? I'm just mentally in a space of logic-this is why we go, better to catch things early, to then a space of emotion-but what if it's worse this time, what if it metastasizes... Just reaching out for some calming support. She checked my lymph nodes and found nothing suspicious, which I am grateful for. Thank you 🙂
