Study Purpose: This research looks at how normal skin cells (melanocytes) change into moles (nevi) and then into a type of skin cancer called melanoma. It aims to understand these changes better, especially in children, adolescents, and young adults (CAYA) with a large birthmark (L/GCMN).
Who Can Join: We are looking for individuals 18 years and older who were born with a large nevus (20 cm or more when fully grown).
Time Commitment: This is a long-term study. Participants will be part of a group where past medical samples are reviewed, so no new visits are needed.
- Key Point 1: Participants must have a large congenital nevus present from birth.
- Key Point 2: No new samples or clinic visits required, as we use existing medical records and samples.
- Key Point 3: Participants must provide consent for their data and samples to be used.
This study could help improve early diagnosis and treatments for skin changes. If you're interested and meet the criteria, consider joining to contribute to this important research.
