Actinic Keratoses: frequently asked questions
What are actinic keratoses?
Actinic keratoses are spots on the skin caused by damage from sunlight, especially on parts of the body that are frequently exposed to the sun. They vary in size and have an increased risk of developing skin cancer.
What do actinic keratoses look like?
They look like rough patches on the skin, often skin-colored, red or brown. They can vary in size and can be felt before they are visible. They are usually located on the face, bald scalp, backs of hands, forearms, shins, and décolletage.
How do you get actinic keratoses?
Overexposure to sunlight or the tanning bed causes actinic keratoses. People with fair skin, especially over the age of 60, are more likely.
How will your doctor know if you have actinic keratoses?
The doctor can determine this visually, but sometimes a small piece of skin is removed for further examination (biopsy) to rule out other skin conditions.
Should you be treated for actinic keratoses?
In most cases, treatment is recommended, especially if there are symptoms, many keratoses present, or cosmetic concerns.
What treatments are available for actinic keratoses?
Several treatments are possible, depending on the severity. These can range from medications to surgical procedures.
What else can you do yourself?
Protect your skin from sunlight, wear protective clothing, use sunscreen and avoid tanning beds. Watch your skin carefully yourself.
When should you see your dermatologist?
With changes such as growths, thickening, pain, or non-healing wounds. Benign spots should disappear on their own after 6 to 8 weeks.
What is the risk of developing skin cancer?
The risk of squamous cell carcinoma in an area with actinic keratoses is about 1% for less than five spots and rises to 20% for more than 20 spots. Regular monitoring is important.
