Actinic Keratosis is considered a precancer, because if gone untreated could develop into a cancer. Actinic Keratosis is often recognized as a scaly and bumpy growth on the skin. This type of growth develops slowly and gets larger over time. Actinic Keratosis is also known to start small, go away and then come back at a later time as a larger growth. Frequent exposure to the sun can cause Actinic Keratosis to develop.
Common areas of development are the hands, back, neck and face. You should consult your doctor about a skin exam to better asses any growths on your skin that you believe are abnormal. Limiting exposure to the sun can help prevent many skin cancers and precancers such as Actinic Keratosis.
