What is a common characteristic of actinic keratosis?

Actinic keratosis is commonly characterized by its potential to develop into skin cancer, specifically squamous cell carcinoma, if left untreated. This skin condition arises as a result of prolonged sun exposure, leading to damaged skin cells. While actinic keratosis itself is not cancerous initially, its ability to progress into a malignant form makes it essential for individuals with this condition to seek monitoring and treatment.

Being benign is not a defining characteristic since, although early lesions are not cancerous, there is still a significant risk for malignancy over time. It is also important to note that while many actinic keratosis lesions can be painless, some may cause symptoms like itching or tenderness, thus not all are completely devoid of discomfort. Therefore, the emphasis on the possibility of becoming cancerous highlights the critical nature of understanding and addressing actinic keratosis effectively.
