If melanoma is suspected under your nail, your doctor will first examine the affected nail and ask about:
- How long you've had the symptoms
- Any changes you've noticed over time
- Your personal and family health history
- Any pain, bleeding or nail separation from the nail bed Your doctor may use dermoscopy - a special magnifying lens with light - to look more closely at the affected area and monitor changes over time. The only way to confirm a diagnosis is through a biopsy, where they'll take a small sample of the affected nail tissue to examine under a microscope.
If melanoma is confirmed, additional tests may be ordered to check if the cancer has spread to other areas of the body. Early detection is crucial - if you notice any dark spots in your toenail without having experienced an injury, or see changes in nail shape, color, or texture, it's important to see a doctor promptly. When caught early, nail melanoma has a survival rate of approximately 95%.
