5 Subtle Signs of Nail Cancer You Might Be Missing
Bleeding
As nail cancer advances, you might notice bleeding under the nail, formation of ulcers, or small lumps (nodules) beneath the nail plate. These symptoms indicate that the cancer is affecting deeper tissues and causing damage.
Bleeding or ulcers under the nail is not common otherwise, and can be painful and may not heal easily.
Nail Discoloration
Nail cancer can cause general discoloration of the nail, such as black, brown, or even red hues. Sometimes the skin around the nail may also darken or show pigmentation changes, a warning sign known as Hutchinson’s sign. This means the pigment extends beyond the nail onto the adjacent skin.
Nail Deformities
Nail cancer can cause the nail to become thinned, cracked, split, or distorted. The nail plate (the hard part of the nail) may look irregular or damaged. Sometimes the nail develops dents, and it may stop growing normally altogether.
Dark Streaks or Bands Under the Nail
One of the most common early signs of nail cancer is a brown or black streak running vertically under the nail. This streak is usually about 3 millimeters wide but can grow wider over time. It may look like a bruise (that occurs due to injury), but unlike a bruise, it does not heal or move as the nail grows.
Nail Lifting
Another symptom to watch for is when the nail starts lifting or separating from the skin underneath (the nail bed). This can make the nail look like it’s coming off or peeling away. Nail separation is often painless in the beginning, but can become uncomfortable or painful as the cancer progresses.
