💅 If You Have Lines on Your Nails, Does It Mean You Have Cancer? Here’s What It Can Mean
You may see claims online that lines on your nails always mean cancer, but that is not true. Nail changes can happen for many reasons, and most are not serious.
Different types of nail lines can mean different things:
1. 🤍 Vertical Lines (Running From Cuticle to Tip)
These are very common, especially with age.
Possible causes:
- Normal aging
- Dry nails
- Frequent hand washing
- Minor nail changes over time
They are usually harmless if they are stable.
2. ↔️ Horizontal Lines (Across the Nail)
These are called Beau’s lines.
They can happen when nail growth temporarily slows due to things like:
- Illness or fever
- Major stress on the body
- Injury to the nail
- Certain medications
- Nutritional problems
3. âš« Dark Vertical Stripe (Black/Brown Line)
A dark line under a nail can have many causes, including:
- Normal pigment changes
- Injury
- Certain skin conditions
Rarely, a new or changing dark streak can be a sign of melanoma under the nail, which needs medical evaluation.
