Skin cancer fact file

Skin cancer occurs when the UV light in sunlight damages the DNA in skin, causing skin cells to mutate and grow into cancers. It's the most common form of cancer in Australia, and Australians have the highest incidence in the world.

What is melanoma skin cancer?

Melanoma is a cancer that begins in the melanocytes – the cells that produce the skin coloring or pigment known as melanin. Melanin helps protect the deeper layers of the skin from the harmful effects of the sun.

What is nonmelanoma skin cancer?

skin cancers are classified as nonmelanoma, usually occurring in either basal cells or squamous cells. These cells are located at the base of the outer layer of the skin or cover the internal and external surfaces of the body.Most nonmelanoma skin cancers develop on sun-exposed areas of the body, like the face, ear, neck, lips, and the backs of the hands. Depending on the type, they can be fast or slow growing, but they rarely spread to other parts of the body.

What is Skin Cancer?

Skin cancer is a disease in which cancer (malignant) cells are found in the outer layers of your skin. Your skin protects your body against heat, light, infection, and injury. It also stores water, fat, and vitamin D.

The skin has two main layers and several kinds of cells. The top layer of skin is called the epidermis. It contains three kinds of cells: flat, scaly cells on the surface called squamous cells; round cells called basal cells; and cells called melanocytes, which give your skin its color.

BASAL CELL & SQUAMOUS CELL
(From the National Cancer Institute PDQ Statement)
There are several types of cancer that start in the skin. The most common are basal cell cancer and squamous cell cancer, which are covered in this PDQ patient information statement.
Skin cancer is more common in people with light colored skin who have spent a lot of time in the sunlight. Skin cancer can occur anywhere on your body, but it is most common in places that have been exposed to more sunlight, such as your face, neck, hands, and arms.
Skin cancer can look many different ways. The most common sign of skin cancer is a change on the skin, such as a growth or a sore that won't heal. Sometime there may be a small lump. This lump can be smooth, shiny and waxy looking, or it can be red or reddish brown. Skin cancer may also appear as a flat red spot that is rough or scaly. Not ail changes in your skin are cancer, but you should see your doctor if you notice changes in your skin.
