Skin Changes

Overview

Common skin changes

Most skin changes are normal and occur with aging. Some common skin growths include:

Moles.

Most moles are harmless. They may change over time. They can gradually get bigger, develop a hair, become more raised, get lighter in color, fade away, or fall off.

Skin tags.

These are harmless growths that appear in the skin folds on the neck, under the arms, under the breasts, or in the groin. They start as small fleshy brown spots and may grow a small stalk.

Seborrheic keratoses.

These skin growths are almost always harmless. They are found most often on the chest or back. Sometimes they're on the scalp, face, or neck. They start as slightly raised tan spots that form a crusty appearance like a wart.

Birthmarks.

BirthmarksBirthmarks are colored marks on the skin that are there at birth or appear shortly after birth. Most birthmarks are harmless and don't need treatment. Many birthmarks change, grow, shrink, or disappear.

Treatment of a skin change depends on what's causing the skin change and what other symptoms you have. Moles, skin tags, and other growths can be removed if they get irritated, bleed, or bother you.
