Actinic Keratosis & Precancerous Lesions: The Early Warning of Skin Cancer
Actinic keratoses (AKs) are rough, scaly, sun-induced lesions that represent the earliest stage of potential skin cancer. Often appearing on the face, scalp, ears, and hands, these precancerous patches may range from subtle, skin-toned areas to reddish-brown scaly growths.
Recognizing AKs is critical, as untreated lesions can evolve into squamous cell carcinoma or increase susceptibility to melanoma. Early evaluation by a board-certified dermatologist ensures accurate diagnosis, risk assessment, and timely intervention. Legacy Dermatology combines clinical expertise and evidence-based protocols to safeguard long-term skin health.


ACTINIC KERATOSIS Progression: From Lesion to Squamous Cell Carcinoma
Actinic keratoses reflect cumulative ultraviolet-induced DNA mutations in skin cells. Left untreated, these abnormal cells may multiply, invade deeper layers, and progress to squamous cell carcinoma.
Early detection and intervention interrupt this progression, prevent malignancy, and maintain healthy tissue integrity, optimizing both safety and aesthetic outcomes.
We treat AKs with cryotherapy, topical medications, or laser therapy for effective removal. Ongoing skin checks and patient education help prevent recurrence and support lifelong skin health.
