How is an actinic keratosis diagnosed?

Most of the time, doctors can diagnose an actinic keratosis just by examining it. If the AK is especially large or thick, a biopsy may be advisable to make sure that the spot in question is just a keratosis and has not become a skin cancer.

There are other spots, called seborrheic keratoses, that are not caused by sun exposure and have no relationship to skin cancers. These are raised brown lesions that may appear on any area of the skin. They also often run in families.
