The Most Common Symptoms of Nail Cancer That People Often Overlook
Nail cancer, a form of subungual melanoma, is a rare but serious condition that can easily be mistaken for less severe issues. This type of cancer develops under the nail and can be easily overlooked due to its subtle symptoms, which many might dismiss as benign nail problems. This article aims to provide an in-depth exploration of these symptoms, supported by evidence-based information, and includes FAQs to address common concerns. Understanding the common symptoms of nail cancer that people often overlook is crucial for early detection and treatment.
1. A Persistent Dark Streak Under the Nail
One of the most common symptoms of nail cancer that people often overlook is the presence of a dark streak running vertically along the nail. Many might dismiss this as a bruise or a common nail discolouration, especially if it doesn’t cause pain. This streak can be brown, black, or even a dark blue, and it typically appears on the thumb or big toe. However, if the streak persists for more than a few weeks and does not grow out with the nail, it is essential to seek medical advice.
According to the World Health Organization (WHO), early detection of nail cancer significantly improves the prognosis. Ignoring this symptom can lead to delayed diagnosis and treatment, which can allow the cancer to spread to other parts of the body.
"Health is a state of complete physical, mental, and social well-being, and not merely the absence of disease or infirmity." – WHO
2. Changes in Nail Texture or Shape
Nail cancer can also manifest as changes in the shape or texture of the nail. People might notice that the nail becomes thicker or more brittle, or that the nail plate starts to lift away from the nail bed (onycholysis). These changes are often attributed to fungal infections, injuries, or aging, which are far more common. However, persistent changes that do not respond to typical treatments should be investigated further.
The WHO emphasises that any unexplained changes in the nail should not be ignored, particularly if accompanied by other symptoms such as pain or discolouration.
"An early diagnosis is the key to the best possible outcomes." – WHO
3. A Slow-Healing Sore on the Nail or Surrounding Skin
Another symptom of nail cancer that people often overlook is the presence of a sore or ulcer on the nail or the surrounding skin that doesn’t heal. This could be mistaken for an injury, a wart, or an infection, especially if it’s not particularly painful. However, a sore that persists for more than a few weeks and resists typical treatments should raise concerns.
WHO guidelines recommend monitoring any skin or nail lesions that do not heal within a reasonable time frame, as this can be a sign of underlying malignancy.
"Awareness and timely action can save lives." – WHO
4. Nail Lifting Off the Nail Bed (Onycholysis)
Onycholysis, or the lifting of the nail from the nail bed, can occur for various reasons, including trauma, infections, or reactions to certain medications. However, when this occurs without a clear cause and is accompanied by other symptoms, it could be indicative of nail cancer. People often overlook this symptom because it is generally painless and can be easily attributed to less severe conditions.
WHO stresses the importance of not dismissing onycholysis, especially if it occurs in conjunction with other unusual nail changes.
"Prevention is better than cure, but early detection is the next best thing." – WHO
5. Discolouration That Spreads Beyond the Nail
Discolouration that extends beyond the nail and onto the surrounding skin (known as Hutchinson’s sign) is a classic symptom of nail cancer that people often overlook. This sign indicates that the melanoma is advancing and may be spreading to other parts of the body. Unfortunately, this symptom is often mistaken for a fungal infection or bruising, especially if there’s a history of trauma to the nail.
According to WHO, the presence of Hutchinson’s sign is a strong indicator of subungual melanoma, and immediate medical consultation is necessary.
"Your body whispers before it screams—listen to those whispers." – WHO
6. A Split in the Nail That Doesn’t Heal
A persistent split or crack in the nail that doesn’t heal can also be a symptom of nail cancer. This can be mistaken for trauma-related damage or a common nail disorder, particularly if there’s a history of injury to the area. So, if the split continues to worsen or doesn’t show signs of healing over time, it could be a sign of something more serious.
WHO advises that any persistent nail abnormalities, especially those resistant to conventional treatments, should be evaluated by a healthcare professional to rule out malignancy.
"Early intervention is the best form of protection." – WHO
7. Pain or Tenderness in the Nail Bed
Pain or tenderness in the nail bed, particularly if it’s persistent and doesn’t improve with typical treatments, is another symptom of nail cancer that people often overlook. This discomfort might be subtle at first, making it easy to dismiss as a minor injury or infection. So, if the pain persists or worsens over time, it’s important to seek medical advice.
WHO notes that while pain is not always present in the early stages of nail cancer, its emergence should not be ignored, especially when combined with other symptoms.
"Listening to your body is the first step towards healing." – WHO
8. A Nail That Changes Colour
A nail that suddenly changes colour, whether it turns white, yellow, or even a shade of blue, can be a sign of nail cancer. While nail discolouration is often associated with fungal infections or minor injuries, a sudden and unexplained change in nail colour should not be overlooked. If the discolouration does not respond to typical antifungal treatments, it’s essential to consult a healthcare professional.
WHO recommends that any unusual or persistent nail discolouration be investigated further, especially when it’s accompanied by other symptoms like nail thickening or lifting.
"Your health is in your hands—take action when something doesn’t feel right." – WHO
9. Swelling or Redness Around the Nail
Swelling or redness around the nail, particularly when it occurs without an obvious cause, can be another overlooked symptom of nail cancer. This swelling might be mistaken for an infection, especially if it’s accompanied by pain or discomfort. However, if the swelling persists despite treatment, it’s important to consider the possibility of nail cancer.
According to WHO, unexplained swelling or redness around the nail should not be dismissed, as it could be an early sign of malignancy.
"Don’t wait for symptoms to worsen—act at the first sign of trouble." – WHO
10. A Nail That Grows in an Unusual Way
If a nail starts to grow in a strange or abnormal manner, it could be an indication of nail cancer. This might include a nail that grows in a twisted or distorted fashion, or one that becomes thicker or more curved over time. While abnormal nail growth can be caused by various conditions, persistent changes should be evaluated by a healthcare professional.
WHO advises that any unusual changes in nail growth be closely monitored, particularly if they are accompanied by other symptoms such as discolouration or pain.
"Early detection is your best defence against serious health conditions." – WHO

FAQs
Q1: What causes nail cancer?
A: Nail cancer, or subungual melanoma, is typically caused by genetic factors and prolonged exposure to ultraviolet (UV) radiation. Unlike skin melanoma, nail cancer is less commonly linked to UV exposure from sunlight. It often occurs in individuals with a history of skin cancer or those who have experienced trauma to the nail area. WHO emphasises the importance of protecting your nails from trauma and monitoring any changes that occur after an injury.
Q2: How is nail cancer diagnosed?
A: Diagnosis of nail cancer usually involves a physical examination by a dermatologist, followed by a biopsy of the affected nail or surrounding tissue. The biopsy is the most definitive way to determine whether the changes in the nail are cancerous. WHO recommends that any persistent or unusual nail symptoms be evaluated by a healthcare professional as early as possible.
Q3: Can nail cancer be treated successfully?
A: Yes, if detected early, nail cancer can often be treated successfully. Treatment options include surgical removal of the affected nail and surrounding tissue, and in some cases, amputation of the affected digit. Radiation therapy and chemotherapy may also be used in more advanced cases. WHO highlights that early detection and treatment are crucial for a positive outcome.
Q4: How can I reduce my risk of developing nail cancer?
A: To reduce your risk of developing nail cancer, it’s important to protect your nails from trauma and avoid prolonged exposure to UV radiation. WHO advises wearing protective gloves when working with chemicals or in environments where your nails might be exposed to injury. Regular self-examination of your nails and seeking medical advice for any persistent changes can also help in early detection.
Q5: Are there other types of cancer that can affect the nails?
A: Yes, other types of cancer, such as squamous cell carcinoma and basal cell carcinoma, can also affect the nails, although they are less common than subungual melanoma. WHO suggests that any unexplained changes in the nails, regardless of the type of cancer, should be evaluated by a healthcare professional.
Q6: Is nail cancer more common in certain demographics?
A: Nail cancer can affect individuals of all ages, genders, and ethnicities, but it is more commonly seen in people over the age of 50 and those with a history of skin cancer. WHO notes that individuals with darker skin tones are more likely to develop subungual melanoma on the hands and feet, highlighting the importance of monitoring nail health in all populations.
Q7: Can nail cancer recur after treatment?
A: Yes, like other forms of cancer, nail cancer can recur after treatment. Regular follow-up appointments with your healthcare provider are essential to monitor for any signs of recurrence. WHO recommends ongoing vigilance and self-examinations to detect any new or recurring symptoms as early as possible.
Conclusion
As the World Health Organization consistently reminds us, our health is our most valuable asset, and taking proactive steps to protect it is essential. Regular self-examinations, seeking medical advice for any concerning symptoms, and following up on treatments can help ensure that nail cancer, if it occurs, is caught and treated early.
Understanding what are the most common symptoms of nail cancer that people often overlook is vital for early detection and treatment. From persistent dark streaks to unexplained changes in nail shape and texture, these signs should not be ignored. Early diagnosis is crucial in improving outcomes, and being vigilant about any unusual changes in your nails can make a significant difference.
