Risk factors for actinic keratosis include the following:

  • Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time.
  • Having a fair complexion, which includes the following:
    • Fair skin that freckles and burns easily, does not tan, or tans poorly.
    • Blue or green or other light-colored eyes.
    • Red or blond hair.

Nonmelanoma skin cancer and actinic keratosis often appear as a change in the skin.

Not all changes in the skin are a sign of nonmelanoma skin cancer or actinic keratosis. Check with your doctor if you notice any changes in your skin.

Possible signs of nonmelanoma skin cancer include the following:

  • A sore that does not heal.
  • Areas of the skin that are:
    • Raised, smooth, shiny, and look pearly.
    • Firm and look like a scar, and may be white, yellow, or waxy.
    • Raised, and red or reddish-brown.
    • Scaly, bleeding or crusty.

Possible signs of actinic keratosis include the following:

  • A rough, red, pink, or brown, raised, scaly patch on the skin that may be flat or raised.
  • Cracking or peeling of the lower lip that is not helped by lip balm or petroleum jelly.

Tests or procedures that examine the skin are used to detect (find) and diagnose nonmelanoma skin cancer and actinic keratosis.

The following procedures may be used:

  • Skin exam: A doctor or nurse checks the skin for bumps or spots that look abnormal in color, size, shape, or texture.
  • Biopsy: All or part of the abnormal-looking growth is cut from the skin and viewed under a microscope by a pathologist to check for signs of cancer. There are three main types of skin biopsies:
    • Shave biopsy: A sterile razor blade is used to "shave-off" the abnormal-looking growth.
    • Punch biopsy: A special instrument called a punch or a trephine is used to remove a circle of tissue from the abnormal-looking growth.

      Punch biopsy. A hollow, circular scalpel is used to cut into a lesion on the skin. The instrument is turned clockwise and counterclockwise to cut down about 4 millimeters (mm) to the layer of fatty tissue below the dermis. A small sample of tissue is removed to be checked under a microscope. Skin thickness is different on different parts of the body.
    • Excisional biopsy: A scalpel is used to remove the entire growth.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) depends mostly on the stage of the cancer and the type of treatment used to remove the cancer.

Treatment options depend on the following:

  • The stage of the cancer (whether it has spread deeper into the skin or to other places in the body).
  • The type of cancer.
  • The size of the tumor and what part of the body it affects.
  • The patient's general health.
