What Is Actinic Keratosis?

As we have already mentioned, actinic keratosis is a pre-cancerous skin condition that is caused by exposure to the sun’s ultraviolet rays. UV radiation can damage the DNA in the skin cells, leading to the development of actinic keratosis. The condition typically appears as a scaly, red lesion on the skin.

What Does Actinic Keratosis Look Like?

Actinic keratosis often looks like a scaly, red patch on the skin.  The lesions can vary in size, from a few millimeters to several centimeters in diameter.

It takes time for the damage from UV radiation to manifest as actinic keratosis. The lesions may not appear for years after the initial exposure to the sun’s rays.

What Is Hypertrophic Actinic Keratosis?

Hypertrophic actinic keratosis is a more severe form of actinic keratosis. The lesions are larger, deeper, thicker, and more raised than regular actinic keratosis. This type of actinic keratosis is more likely to develop into cancer than the regular form.
