What does actinic keratosis indicate?

Actinic keratosis indicates sun damage to the skin that can develop into precancerous lesions. This condition typically arises from prolonged exposure to ultraviolet (UV) light from the sun or tanning beds. It presents as rough, scaly patches on sun-exposed areas of the skin, such as the face, ears, and hands.

The significance of actinic keratosis lies in its potential to progress to squamous cell carcinoma, which is a type of skin cancer. Thus, it serves as a warning sign for more serious health issues related to UV exposure. Recognizing this condition is crucial for early intervention to prevent further skin damage and the possible development of skin cancer.

Other options do not accurately describe actinic keratosis. Hormonal changes may contribute to various skin conditions but are not the cause of actinic keratosis. Symptoms of dryness are typically associated with different skin issues that do not carry the same risks as actinic keratosis. Lastly, actinic keratosis is not caused by bacterial infections; instead, it is primarily related to UV exposure.
