What are actinic keratoses commonly considered?

Actinic keratoses are commonly considered sun-damaged precancerous lesions due to their development as a result of prolonged exposure to ultraviolet (UV) radiation. These lesions typically appear as rough, scaly patches on sun-exposed areas of the skin, such as the face, ears, scalp, and back of the hands.

The key characteristic that defines actinic keratoses is the potential for these lesions to progress to squamous cell carcinoma if left untreated. This relationship between UV exposure, skin changes, and cancer risk underscores why actinic keratoses are closely monitored and often treated by dermatologists.

Understanding that actinic keratoses are precancerous highlights the importance of sun protection strategies and regular skin examinations. By recognizing these lesions early, individuals can take proactive steps to minimize their risk of developing skin cancer associated with UV damage.
