4 Changes in Hands and Feet That Could Be Early Signs of Cancer
Our nails and feet can reveal a lot about our overall health. In some cases, subtle changes in the nails and skin on the hands and feet can be early warning signs of serious health conditions, including cancer. Recognizing these signs early and seeking medical advice can improve the chances of early detection and treatment. Here are four changes you should never ignore.
1. Dark or Black Lines Under the Nails
A sudden appearance of a dark streak or black line under the fingernails or toenails could be a warning sign of subungual melanoma, a rare but aggressive type of skin cancer.
Signs to Watch For:
A dark brown or black stripe running along the nail.
The discoloration does not move as the nail grows.
The surrounding skin becomes darker or swollen.
Nail changes occur without injury.
Why It Matters:
Subungual melanoma is often misdiagnosed as a fungal infection or bruise. Early detection is crucial to prevent the cancer from spreading.
2. Clubbing of the Fingernails (Rounded, Bulging Nails)
Clubbing occurs when the tips of the fingers become wider and rounder, and the nails curve downward. This change can indicate low oxygen levels in the blood, which may be linked to lung cancer or heart disease.
Signs to Watch For:
Fingertips appear swollen or bulbous.
Nails curve downward and become shiny.
The angle between the nail and the cuticle increases.
Thickening of the fingertips over time.
Why It Matters:
Clubbing is often a sign of lung cancer, chronic lung disease, or heart problems. If you notice these changes, consult a doctor immediately.
3. White or Pale Lines on the Nails (Leukonychia)
White spots or pale horizontal lines across the nails, known as leukonychia, can indicate nutrient deficiencies or, in rare cases, an underlying serious illness such as liver disease or cancer.
Signs to Watch For:
White streaks or lines running across multiple nails.
Nails appearing completely white or pale.
Brittle or easily breakable nails.
Why It Matters:
While occasional white spots are harmless, persistent white streaks can signal liver disease, kidney failure, or cancer. It’s essential to get checked if this symptom appears suddenly.
