Black lines on the nails can indicate the presence of melanoma, a dangerous form of skin cancer
A black line on the nail can be caused by a number of factors, including nail injury, infection, or cancer. If you notice a black line on your nail, it is important to see a doctor as soon as possible. A doctor will be able to perform exams to determine whether the black line is malignant or cancerous.

Dark stripes on nails typically appear due to increased deposits of melanin, which gives skin its colour
There are several other causes of dark stripes on nails, including nail injury, infection, or the use of certain medications, such as blood thinners. If you notice a dark stripe on your nail, it is important to consult a healthcare professional. They will typically ask about your medical history and may perform a nail biopsy to determine if there are any cancerous cells present.
It is worth noting that most causes of black lines on the nail do not require treatment. However, if the dark stripe is due to melanoma, a healthcare professional will usually remove the affected area, including the skin under the fingernail. Early detection is crucial, as melanoma can be a serious condition. Therefore, if you notice any changes in your nails, it is always best to seek medical advice.
Additionally, it is important to be mindful of potential risk factors for skin cancer. For example, even short periods of exposure to UV light can increase the risk of skin cancer. This is particularly relevant for individuals who undergo gel manicures, as UV light is used in the curing process. By being aware of these risk factors and monitoring any changes in your nails, you can take proactive steps to maintain your health and well-being.

A doctor can perform exams to determine whether melanonychia is malignant
A doctor can perform several exams to determine whether melanonychia is malignant. The diagnostic process for dark lines under the fingernails usually starts with a person’s medical history, including whether the patient has a history of taking blood thinners, such as warfarin or aspirin, which could explain splinter haemorrhages. A doctor may also perform a physical examination of the nails, determining the number of affected digits and observing the pattern and colour of the melanonychia.
A doctor may also do a dermatoscopic exam using a specific type of microscope to closely examine the discoloured areas. They typically look for signs that your melanonychia may be malignant.
In some cases, a doctor may require further tests to aid diagnosis. They may take a biopsy or sample of the nail area. They will send this biopsy to a pathologist, who can identify if any cancerous cells might be present. This procedure involves removing a part of the nail and looking at the cells of the streak more closely. This analysis remains the gold standard for an accurate diagnosis.
