Actinic Keratosis Precancerous Growths

Overview
This condition, also known as solar keratosis, is a
common precancerous growth that develops on the
skin. It is characterized by small, rough patches
called keratoses. These growths are most
commonly found on the face, hands, forearms and
neck, and should be examined by a doctor.
Causes
Actinic keratosis is caused by frequent or intense
sun exposure and usually takes years to develop.
These rough patches form in the skin’s outer layer
when skin cells are damaged by UV radiation. This
condition occurs most frequently in older adults,
especially those with fair skin and light hair and
eyes. While actinic keratoses are considered
benign, they may develop into skin cancer if left
untreated.
Symptoms
The main symptom of actinic keratosis is the
appearance of rough, discolored patches on the
skin that won’t go away. Usually, the keratoses
form in groups, although a single keratosis can be
relatively small – about the size of a pencil eraser.
They may itch or sting and are sometimes
surrounded by red, irritated skin.
Prevention and Treatment
Actinic keratosis can be prevented by reducing sun
exposure and by using sunscreen. Once a
keratosis has formed, it should be examined and
treated by a doctor to prevent possible progression
into skin cancer. Options for removing the
keratoses include freezing, creams or ointments,
chemical peeling, laser therapy, or scraping.
Removal of the growth is usually effective.
