A mom thought a brown streak on her nail was just a vitamin issue—turns out, it was a rare and deadly skin cancer called subungual melanoma. She only got it checked after seeing a TikTok, and it probably saved her life! If you spot a weird dark line or streak on your nail that doesn’t go away, don’t ignore it. Nail polish can hide warning signs, so take a sec to check under there. Early detection is everything! #MelanomaAwareness #CheckYourNails #HealthAlert #SkinCancer #RealStories #Health
