Home > Health Library > Actinic Keratosis
Actinic keratosis is a skin growth caused by sun damage. It can turn into skin cancer, but this isn't common. Actinic keratoses, also called solar keratoses, are small red, brown, or skin-colored scaly patches. They are most common on the face, neck, hands, and forearms.
Your doctor can remove these growths by freezing or scraping them off or by putting medicines on them.

Actinic keratosis may turn into skin cancer, but this isn't common. There is no way to find out whether actinic keratosis will progress to squamous cell carcinoma or how fast this might occur. Keratoses on the ear and lip are at the highest risk of developing into cancer because of how sensitive the ear and lip are to sun exposure.
You can help prevent actinic keratosis by staying out of the sun and using sunscreen when you are in the sun. You should also examine your skin for the condition and other suspicious growths once a month, especially if you spend a lot of time in the sun.
