Actinic keratosis is a common skin condition that is a pre-cancerous sign of skin cancer. Rough, scaly patches occur from long sun exposure and most frequently on areas like the face, scalp, ears, hands, and arms. Actinic keratosis is non-cancerous, but it can become squamous cell carcinoma, a skin cancer, if not treated. Understanding what it is and how it occurs is vital for early detection and prevention.
What is Actinic Keratosis?
Actinic keratosis is most often caused by prolonged and repeated exposure to ultraviolet (UV) radiation from the sun or tanning beds. With prolonged exposure, UV damage impairs the repair function of the skin, leading to abnormal cell growth. Certain risk factors develop AK, including:
- Frequent Sunlight Exposure – Individuals with much outdoor activity with minimal sun protection are at a high risk.
- Fair Skin – People with light skin, red hair, and blue, green eyes have less natural sun protection and increased susceptibility to UV damage.
- Compromised Immune System – Individuals with compromised immune systems from medical conditions or medication may be more likely to develop AK.
- Aging – With increasing age, the risk for AK grows, as the cumulative effect of sun exposure eventually affects the skin.
Understanding the Signs of Actinic Keratosis
Actinic keratosis commonly presents as rough, scaly patches in areas of the skin that receive sun exposure. The patches can be flesh-coloured, red, red-brown, or brown in colour. Other symptoms are:
- Dry, sandpapery roughness on the skin
- A feeling of stinging, itching, or soreness in the affected areas
- Thickening or hardening overtime
- Dryness with crusting or mild peeling that resembles dry skin
Since actinic keratosis has the possibility of developing into skin cancer, it is important to watch for any new spots, changes in existing spots, and seek professional examination.
