DEAR DOCTOR K: I saw my doctor about a patch of rough, brown skin that I noticed on my upper arm. He said it is actinic keratosis and needs to be removed. Is it cancer? How will it be removed?
DEAR READER: Actinic keratosis (AK) is a precancerous skin condition. That means it is not cancer now, but is likely to become cancerous if left untreated. AK appears as raised, scaly pink or red-brown rough patches on the skin. The patches are most likely to appear on the face, back of the hands or other areas commonly exposed to the sun. They can cause discomfort and itching.
