This is Dr. David
these are called longitudinal melanonychia
most of the time they are benign and are from excessive melanin cell growth in the nail bed
in rare cases they can be a sign of nail bed melanoma cancers of the skin cells in the nail bed.
you should see a doctor and have the nail evaluated.
you might need a nail bed biopsy to tell for sure if ti is cancer
let me know if you have questions.
