Understanding Actinic Keratosis (AK) and Its Risks

AK is a chronic skin condition caused by long-term sun exposure and characterized by slow-growing lesions. AKs are small, crusty or scaly bumps that show up on or beneath the skin's surface.

AK is the most common precancerous condition. Approximately 10% of AKs ultimately become cancerous, and nearly half of all squamous cell carcinomas (skin cancers) begin as untreated AKs.

The risk of AK increases with age, and although it can occur in people as young as 40, AK is most common in those between the ages of 60 and 74. In addition to age, the risks for AK include a history of prolonged sun exposure (especially sunburns), light eyes and skin tone, and a compromised immune system.

AK can occur anywhere on the body that has been exposed to the sun. Identifying and treating AK as early as possible greatly reduces the risk that it will become skin cancer. This is why it is important to perform monthly skin checks as well as to have your doctor perform annual skin exams. Also, you should see your dermatologist if you notice any changes in your skin.

Talking to Your Dermatologist About AK and How to Treat It

There are a several treatments for AK3:

  • Cryosurgery freezes the AKs
  • Photodynamic therapy removes the lesions with light-activated acid
  • Topical therapy uses medicated gels and creams to destroy AK lesions

Here are some questions you might want to ask your doctor if you are diagnosed with AK:

  • What are my best treatment options?
  • What are the side effects of the chosen AK treatment?
  • How will I know if I am having an abnormal reaction to the treatment?
  • Will I get new AKs?
  • Can I still continue to enjoy outdoor activities during and after AK treatment?
  • When should I return for a follow-up visit?

Before you leave your doctor's office, be sure you understand exactly how to use any medications you are prescribed.
