Actinic keratosis, often referred to as solar keratoses, are rough, flaky skin lesions resulting from prolonged exposure to ultraviolet (UV) rays. Despite being a common condition, many individuals have questions about the potential consequences of leaving these lesions untreated. This article addresses the frequently asked questions about actinic keratosis and the importance of early intervention.

FAQs About Actinic Keratosis

1. Consequences of Untreated Actinic Keratosis

Untreated actinic keratoses may progress to skin cancer. Prior occurrences that resolved spontaneously do not guarantee future regression, especially with continued UV exposure. The risk of mortality from skin cancer is significant, with daily fatalities in the United States alone. It is imperative to address these lesions to mitigate the risk.

2. Preventive Measures

Post-treatment, preventive actions are crucial to avoid recurrence. Utilize broad-spectrum sunscreen to shield your skin from both UVA and UVB rays. SPF 15 may suffice for darker skin tones, but SPF 30 or higher is recommended for extended sun exposure or lighter skin.

3. Treatment Options

Treatment choices for actinic keratosis are varied. For isolated lesions, cryotherapy using liquid nitrogen is commonly recommended. For widespread lesions, daily application of topical medications such as 5-fluorouracil (5-FU), Solareze gel, or Aldara cream may be prescribed for several weeks.

4. Areas Prone to Lesions

Actinic keratosis can emerge on any sun-exposed skin, typically appearing on the forearms, back of hands, and also potentially on the neck, lips, ears, and face. Tanning bed use may increase the risk of lesions on the abdomen or thighs.

5. Symptoms of Actinic Keratosis

The primary symptom is a rough, scaly patch, often less than an inch in diameter, which can be brown, red, or pink. These patches may be flat or slightly raised, sometimes with a warty texture, and may be accompanied by a sensation of burning or itching.

6. Risk Factors

While anyone can develop actinic keratosis, certain factors increase the likelihood, such as a weakened immune system due to certain conditions or medications, blond or red hair, light-colored eyes, a tendency to freckle or burn, and age over 40. Prolonged sun exposure, especially in sunny regions, also raises the risk.

7. Diagnosis

Diagnosis typically involves a visual skin examination, with a skin biopsy being a rare requirement. Post-diagnosis, annual check-ups are recommended to monitor for skin cancer signs.

8. Appointment Expectations

At your appointment, expect a thorough skin inspection and questions regarding the first detection of lesions, their progression, and any discomfort they cause. Be prepared to discuss any changes observed and preventive measures you've adopted, such as sun protection and sunscreen use.

Actinic keratosis, while not immediately life-threatening, is a serious condition that should not be overlooked. Early detection and treatment are vital to prevent potential progression to skin cancer. By understanding the symptoms, risk factors, and available treatments, individuals can take control of their skin health and reduce the risk of more severe dermatological conditions.
