True or False: Most actinic keratosis cases develop into skin cancer.

The assertion that most actinic keratosis cases develop into skin cancer is false. Actinic keratosis (AK) is a precancerous skin condition often caused by prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds. While it is true that AK can progress to squamous cell carcinoma (a type of skin cancer), the majority of AK cases do not progress to cancer.

Statistical data suggests that only a small percentage of actinic keratosis lesions—estimates range from 0.1% to 20%—will evolve into invasive cancer if left untreated. Therefore, while there is a risk associated with AK, it is not correct to state that most cases will develop into skin cancer. This understanding emphasizes the importance of monitoring and managing actinic keratosis, rather than inducing undue alarm about its potential progression.
