Overview

• Lauren Koltcz, a 45-year-old teacher from North Royalton, Ohio, noticed a brown streak on her thumbnail that was later diagnosed as subungual melanoma.
• A TikTok video by dermatologist Dr. Lindsey Zubritsky urged viewers to seek medical attention for dark nail streaks, prompting Lauren to act after months of delay.
• Specialists at the Cleveland Clinic confirmed the melanoma was in situ, meaning it was confined to the upper layer of skin and had not spread.
• Lauren underwent surgery to remove her left thumbnail and surrounding tissue, eliminating the cancer without the need for chemotherapy or radiation.
• Now cancer-free, Lauren emphasizes the importance of early detection and urges others to prioritize health checks for unusual symptoms.
