Actinic keratosis usually affects older adults. Reducing sun exposure can help reduce risk.
It is most common on the face, lips, ears, back of hands, forearms, scalp, and neck. The rough, scaly skin patch enlarges slowly and usually causes no other signs or symptoms. A lesion may take years to develop.
Because it can become cancerous, it's usually removed as a precaution.
Very common: More than 3 million US cases per year
