Symptoms of Actinic Keratosis
The patches are usually red or pink in color, but they can also look brown, tan or light gray and feel firm and/or gritty. They are usually flat or somewhat raised, but they can have a scaly, flaky wart-like appearance. The skin that surrounds the patches often appears thin and delicate. The lesions may also burn and itch.

Consult a doctor about Actinic Keratosis
They should be examined by a doctor, especially if they grow or bleed. Cancerous lesions can be  difficult to differentiate from benign skin growths, and a biopsy is required to rule out squamous cell cancer.
