Have you ever noticed something unusual about your toenail? Perhaps a dark streak, an odd discoloration, or a change in texture that you can’t quite explain? While it might be tempting to dismiss these changes as a result of a recent pedicure or a minor injury, they could be warning signs of something more serious: subungual melanoma. This rare but potentially dangerous form of skin cancer develops under the nail bed and is often mistaken for benign conditions like toenail trauma or fungal infections. Understanding the signs, risk factors, and the importance of early detection could save your toe—or even your life.
What Is Subungual Melanoma?
Subungual melanoma is a type of melanoma that forms under the nail bed, affecting either the toenails or fingernails. Unlike more common forms of skin cancer that appear on the skin’s surface, subungual melanoma is hidden beneath the nail, making it harder to detect. It often starts as a dark streak or spot under the nail, which can easily be mistaken for a bruise or a fungal infection. However, unlike these benign conditions, subungual melanoma does not go away on its own. Over time, it can spread to surrounding tissues and, if left untreated, to other parts of the body.
Common Signs to Watch Out For
When it comes to toe nail cancer, your toenails might be sending you a distress signal. Here are some key signs to watch out for:
Dark Streaks: One of the most common early signs of subungual melanoma is a vertical dark line, usually brown or black, that appears under the nail. Unlike a bruise, this streak does not grow out with the nail or fade over time.
Discoloration: Unusual colors under the nail, such as brown, black, or even red, can be a warning sign. If the discoloration looks uneven or spreads beyond the nail bed, it’s time to consult a professional.
Nail Texture Changes: If your nail becomes thicker, more brittle, or starts to detach from the nail bed without any apparent trauma, it could be a sign of subungual melanoma.
Bleeding or Oozing: Unexpected bleeding from under the nail or the surrounding skin, especially without an injury, is a red flag that should not be ignored.
Tenderness or Swelling: Pain, tenderness, or swelling around the nail that isn’t related to a stubbed toe or tight shoes could indicate an underlying issue.
If you notice any of these signs, don’t brush them off as aging nails or a bad pedicure. Early detection is crucial for effective treatment.
Risk Factors: Why Me?
While anyone can develop subungual melanoma, certain factors may increase your risk:
UV Exposure: Chronic exposure to ultraviolet (UV) light, whether from the sun or tanning beds, can increase your risk of developing melanoma, including subungual melanoma. Even though nails provide some protection, prolonged UV exposure can still damage the cells under the nail bed.
Trauma: Repeated injuries to the toenail, such as from running or wearing tight shoes, can trigger abnormal cell growth and increase the risk of subungual melanoma.
Family History: If you have a family history of melanoma, you may be at a higher risk of developing subungual melanoma. Genetics can play a significant role in your susceptibility to skin cancer.
Skin Tone: Subungual melanoma is more common in individuals with darker skin tones, particularly on the big toe or thumb. This is because melanoma in people with darker skin often occurs in areas that are not exposed to the sun, such as under the nails.
Age: While subungual melanoma can occur at any age, people over 50 tend to be at higher risk. However, it’s important to note that this condition is not exclusive to older adults.
Why Early Detection Is Critical
One of the most challenging aspects of subungual melanoma is that it often doesn’t cause noticeable symptoms until it has progressed to an advanced stage. By the time it’s diagnosed, the cancer may have already spread to other parts of the body, making treatment more difficult. This is why early detection is so critical. When caught in its early stages, subungual melanoma can often be treated successfully with surgical excision, which involves removing the affected nail and surrounding tissue.
What to Do If You Notice Symptoms
If you notice any unusual changes in your toenails, don’t panic—but don’t ignore them either. Take a deep breath and ask yourself: Is this streak or discoloration new? Is it persistent? Does it look unusual? If the answer to any of these questions is yes, it’s time to consult a professional.

Treatment Options for Subungual Melanoma
If subungual melanoma is diagnosed, the primary treatment is usually surgical excision. This involves removing the affected nail, nail bed, and any surrounding tissue that may be involved. In some cases, a biopsy of nearby lymph nodes may be necessary to determine if the cancer has spread. Early-stage subungual melanoma has a high success rate with surgical treatment, but advanced cases may require additional therapies such as chemotherapy or radiation.
Prevention Tips
While not all cases of subungual melanoma can be prevented, there are steps you can take to reduce your risk:
Protect Your Nails from UV Exposure: Wear sunscreen on your hands and feet, especially if you spend a lot of time outdoors. Consider wearing gloves or UV-protective clothing if you’re going to be in the sun for extended periods.
Avoid Nail Trauma: Be mindful of activities that could cause repeated trauma to your nails, such as running or wearing ill-fitting shoes. If you do experience a nail injury, monitor it closely for any changes.
Regular Self-Exams: Make it a habit to check your nails regularly for any unusual changes. Early detection is key to successful treatment.
Consult a Professional: If you notice any persistent changes in your nails, don’t hesitate to consult a podiatrist or dermatologist. It’s always better to be safe than sorry.
