What it means

A slow-growing skin cancer, usually on sun-exposed skin such as the face, ears, neck and hands. It may look like a shiny, pearly bump, a pink patch, or a sore that bleeds, heals and comes back. It rarely spreads to other organs but can damage nearby tissue if left untreated. It is usually removed with minor surgery.

For the nurse

Teach sun safety: sunscreen, hats, shade, no tanning beds, and checking the skin regularly. Report any sore that does not heal within a few weeks.
