@knowledgedome: At 35, British woman Lucy Thomas from East Yorkshire was diagnosed with a rare type of skin cancer after noticing a thin, dark line under her thumbnail. She often wore acrylic and fake nails and initially thought the mark was just a small bruise or an injury. A friend encouraged Lucy to get it checked by a doctor. After a hospital examination and biopsy, doctors reportedly found precancerous changes and diagnosed her with subungual melanoma, a rare form of skin cancer that develops under a fingernail or toenail. Her story is a reminder that unusual changes in your nails should never be ignored. A dark line under a nail does not always mean cancer, but if it is new, changing, or unexplained, it is important to get it checked by a medical professional.
