The human nails are indicative of our overall health and wellness. However, often, people tend to overlook them in their pursuit of keeping their bodies healthy. Nails serve as a warning sign for a plethora of underlying health conditions.

Cancer is one such ailment that can manifest in the nails. Nail changes associated with cancer can be indicative of the disease’s presence in the body. If you notice any such changes in your nails, you should consult your physician.

Discoloration

Discoloration is a common nail change associated with cancer. If you notice a brown or black line on the nails, it can be a sign of skin cancer. However, it is not always the case. It could also be due to a fungal infection, psoriasis, or an injury.

If the discoloration is vertical and extends past the cuticle, it could indicate melanoma – a type of skin cancer.

Changes in the shape of the nail

Cancer can change the shape or curve of the nail. If you notice changes in the nail’s shape, such as a nail that curves downward, it could be a sign of lung cancer.

Clubbing, where the nail’s shape changes, making it wider or rounder, is a common nail change associated with lung cancer, heart disease, and liver disease.

Pitting and ridges

Pitting and ridges on the nail are common symptoms of nail psoriasis. If you notice pitting on the nails, it could indicate an underlying psoriasis condition.

However, in rare cases, pitting can be associated with lymphoma, a type of cancer that affects the lymphatic system.

Brittle and cracked nails

Brittle, dry, or cracked nails are often associated with nutrient deficiencies, such as a lack of vitamins A, C, and biotin. However, brittle and cracked nails can also be indicative of thyroid problems or fungal infections.

In rare cases, it can be a sign of nail melanoma.

Bleeding under the nail

Bleeding under the nail, also known as ‘subungual hematoma,’ could be due to an injury or a fungal infection. However, if it appears out of nowhere and persists, it could be a sign of skin or bone cancer.

Nail separation

If your nail appears to be separating from the nail bed, it could be a sign of psoriasis or a fungal infection. However, in rare cases, it can indicate skin cancer or thyroid disease.

Yellowish nails

Yellow nails are common with fungal infections but can also be due to underlying health conditions. If your nails appear yellowish, it could be a sign of liver or kidney disease, thyroid issues, or diabetes.

White spots on the nails

Contrary to popular belief, white spots or lines on the nails are not indicative of a calcium deficiency. They are typically due to injury, nail trauma, or bouts of illnesses such as the flu.

However, if these spots persist and grow in size, it could be indicative of a fungal infection or a sign of kidney disease or liver problems.

Conclusion

While nail symptoms can be associated with cancer, they could also be indicative of other underlying health conditions. Therefore, consult your physician if you observe any sudden changes in your nails.

It is important to remember that early diagnosis and treatment are crucial for the successful management of cancer.
