Changes in the appearance of your nails can be harmless, but they can also indicate an underlying disease. A recent study by the National Institutes of Health (NIH) found that benign nail abnormalities could be linked to a rare inherited disorder that increases the risk of developing cancerous tumors. While this discovery is significant, it is important to note that nail changes can have various causes, and further investigation is often needed to determine the underlying issue. In this context, the question arises: Are bent fingernails a sign of cancer, and what other nail changes could be indicative of potential health concerns?

Nail clubbing can be a sign of lung cancer
Changes in the appearance and structure of your nails can indicate an underlying health condition. One such change is nail clubbing, which is often associated with lung cancer. Nail clubbing is characterised by nails that appear wider, spongy, swollen, or like an upside-down spoon. It is typically caused by excessive amounts of growth factors that encourage the growth of blood vessels.
Lung cancer is not the only type of cancer that can cause nail clubbing. Esophageal cancer, Hodgkin lymphoma, and rhabdomyosarcoma have also been linked to this nail condition. Additionally, certain medications used to treat lung cancer may also cause nail changes and swelling of the fingertips, further complicating the diagnosis.
The development of nail clubbing due to lung cancer or other chronic conditions is usually long-term or permanent. Treating the underlying condition may help nails return to normal. However, nail clubbing itself does not require treatment, and the focus is typically on addressing the cancer or underlying cause.
It is important to be vigilant about any changes in your nails, as they can be indicative of your overall health. If you notice nail clubbing or any other unusual nail changes, it is recommended to consult a healthcare provider or a board-certified dermatologist for further evaluation and appropriate treatment.

Horizontal ridges on nails can be caused by chemotherapy
While nail ridges are usually harmless, they can sometimes indicate an underlying health problem. Horizontal ridges, or Beau's lines, can be indicative of malnutrition, serious nail injury, or even a serious condition such as acute kidney disease. Beau's lines are also often associated with chemotherapy treatment for cancer.
Chemotherapy, a common treatment for cancers such as breast cancer and colon cancer, can cause horizontal ridges to appear on the nails. These ridges are known as Beau's lines. With each infusion, the nail plate stops growing, creating temporary disruptions that result in ridged nail growth. Chemotherapy drugs like taxotere and targeted therapy drugs like fibroblast growth factor receptor (FGFR) inhibitors may also cause nails to lift from the nail bed or come off entirely.
Beau's lines can be a source of concern for patients undergoing chemotherapy, as they can indicate a disruption in nail growth. However, it is important to note that these ridges are typically not symptomatic and do not require medical intervention. Patients should, however, be vigilant about monitoring any changes in their nails and consult a doctor if they experience symptoms such as pain or odour, as this may indicate an infection or other underlying condition.
While chemotherapy can cause temporary nail changes, it is reassuring to know that most patients' nails will grow back healthy after completing cancer treatment. However, in some cases, the side effects of chemotherapy on the nails may be longer-term. Some patients may experience thickened, painful nails that require intervention, such as nail removal, to alleviate discomfort.
It is always advisable to consult a healthcare professional if you notice any changes in your nails, as they can provide guidance and treatment options to manage any discomfort or address any underlying conditions.

Dark streaks on nails could be melanoma
While changes in the appearance of your nails can occur for harmless reasons, they can also be a sign of an underlying health condition. It is important to see a doctor or a board-certified dermatologist if you notice any changes to your nails, as they can provide a diagnosis and direct treatment at the underlying cause.
Melanonychia, which is the appearance of a dark line on your fingernails or toenails, can be benign or malignant. It is caused by an increase in the production and deposits of melanin in your nail, which results in a brown or black stripe on the nail. While melanonychia may appear in one nail or several, subungual melanoma usually only appears on one nail.
If you notice a new or changing dark streak on your nail, it is important to see a dermatologist as soon as possible. Early detection and prompt treatment of subungual melanoma yield the best outcomes. A biopsy of the nail is the best way to get an early diagnosis. If the melanoma is caught early, before it spreads, it is more likely to be successfully treated.

Curved nails can indicate lung cancer
While curved nails can sometimes be a harmless trait that runs in the family, they can also be indicative of lung cancer. This condition is called nail clubbing, which causes nails to appear wider, spongy, swollen, and curved downwards like the round part of an upside-down spoon. It is often associated with diseases of the heart and lungs, such as lung cancer, lung infections, interstitial lung disease, cystic fibrosis, and cardiovascular disease.
Nail clubbing is a change in the appearance and structure of the fingernails or toenails and is usually a sign of an underlying health condition. Besides lung cancer, other cancers that can cause nail clubbing include oesophageal cancer, Hodgkin lymphoma, and rhabdomyosarcoma. Additionally, hyperthyroidism and Grave's disease have been known to cause nail clubbing in some people.
It is important to note that nail clubbing itself is usually not harmful or painful. However, it often indicates a serious health condition that requires medical attention. Treating the underlying cause of nail clubbing can help nails return to their normal state. For example, a treatment plan for lung cancer may include chemotherapy, surgery, radiation therapy, or medications.
If you notice any changes in your nails, such as curving, it is recommended to consult a healthcare provider or a board-certified dermatologist. They can help evaluate any nail changes and determine whether they are harmless or require further medical testing.

BAP1 gene mutation can cause bent finger nails and increase cancer risk
While bent fingernails can be harmless, they can also be indicative of an underlying health condition. One such condition is onychopapilloma, a benign nail tumour abnormality that causes a coloured band (usually white or red) along the length of the nail, accompanied by thickening of the nail underneath the colour change and at the end of the nail. This condition typically only affects one nail. However, in a recent study, 88% of participants aged 30 and older with known BAP1 tumour predisposition syndrome (TPDS) exhibited onychopapilloma tumours on multiple nails.
BAP1 TPDS is a rare inherited disorder caused by mutations in the BAP1 gene, which normally functions as a tumour suppressor. These mutations result in a complete loss of BAP1 protein function in tumour cells, impairing the removal of ubiquitin from certain proteins. While the exact mechanism by which the loss of BAP1 function leads to tumour formation is not fully understood, researchers theorise that altered activity of BAP1-regulated proteins may promote cell proliferation or survival, resulting in tumours.
The presence of onychopapillomas on multiple nails can be an indicator of BAP1 TPDS. Individuals with this syndrome have an increased risk of developing cancerous tumours of the skin, eyes, kidneys, and the tissue that lines the chest and abdomen (such as the mesothelium). Cancers associated with BAP1 TPDS include mesothelioma, melanoma, renal cell cancer, and basal cell carcinomas. When cancers occur in people with BAP1 TPDS, they tend to be more aggressive and have a shorter survival rate than in the general population.
While nail changes can be a sign of BAP1 TPDS and an increased cancer risk, it is important to note that not all people with BAP1 gene mutations will develop tumours. Additionally, nail changes can be caused by various other factors and conditions, including digestive conditions like Crohn's disease and celiac disease, thyroid conditions, and cardiovascular disease. Therefore, if you notice any persistent nail changes, it is always advisable to consult a healthcare professional for proper evaluation and diagnosis.
