In medical terms, AK often refers to Actinic Keratosis.
Actinic Keratosis Explained
Actinic keratosis (AK) is a common skin condition. According to Yale Medicine, it's characterized by rough, scaly patches or small growths on the skin's surface. These are typically caused by long-term exposure to ultraviolet (UV) radiation from the sun or tanning beds. AKs are considered precancerous and can potentially develop into squamous cell carcinoma if left untreated.
Key Characteristics of Actinic Keratosis:
- Appearance: Rough, dry, scaly patches or bumps on the skin.
- Location: Commonly found on sun-exposed areas such as the face, scalp, ears, and hands.
- Cause: Prolonged exposure to UV radiation (sun or tanning beds).
- Significance: Precancerous lesions with a risk of developing into skin cancer.
