Black lines on nails can be a cause for concern, as they can indicate the presence of melanoma, a dangerous form of skin cancer. This is known as subungual melanoma, and one type is acral lentiginous melanoma (ALM). However, ALM is a rare type of melanoma. Black lines on nails can also be caused by injury, infection, vitamin deficiencies, or other health conditions. It is important to consult a healthcare professional if you notice any changes to your nails, especially if they are painful, bleeding, or occur without explanation.
