Seborrheic keratosis is a type of benign raised growth on the skin. The growths develop from the top layer of skin. These growths may look like warts, but do not extend deep into the skin, or contain the viruses that cause warts.
Seborrheic keratoses are not contagious, do not spread, or do not turn into cancerous tumors. In most cases, treatment is not required.
