The plural form of "actinic keratosis" is "actinic keratoses".
1 answer
Actinic Keratosis is a type of precancer that can cause visible lesions on skin. If you have Actinic Keratosis, then you have sustained sun damage and could potentially develop skin cancer.
1 answer
The main risk of actinic keratosis is of skin cancer. This mainly has to do with the fact that actinic keratosis is caused by sun damage to skin, as is most skin cancer.
1 answer
Actinic keratosis is a precancerous growth on the skin.
Alternative NamesSolar keratosis; Sun-induced skin changes - keratosis; Keratosis - actinic (solar)
Causes, incidence, and risk factorsActinic keratosis is caused by sun exposure.
Risk factors for actinic keratosis include:
- Having fair skin, blue or green eyes, or blond or red hair
- Long-term, daily sun exposure (for example, if you work outdoors)
- Multiple, severe sunburns early in life
- Older age
- Rough and dry skin lesion
- Patch or growth on the skin
- Limited to one area (localized)
- Located on the face, scalp, back of the hands, chest, or other sun-exposed areas
- Gray, pink, red (erythematous), or the same color as the skin
- Begins as flat and scaly areas
- Later develops a hard and wart-like or gritty, rough, and "sandpapery" surface -- may develop a horn-like texture
The skin lesion may be easier to feel than to see.
Signs and testsThe health care provider makes the diagnosis based on the appearance of the skin growth. A skin biopsy may reveal any cancerous changes, if they occur.
TreatmentBecause actinic keratoses are precancerous changes, have them examined promptly. Follow your health care provider's advice for treatment.
Growths may be removed by:
- Burning (electrical cautery)
- Curettage and electrodesiccation (scrapes away the lesion and uses electricity to kill any remaining cells)
- Excision (cutting the tumor out and using stitches to place the skin back together)
- Freezing (cryotherapy, which freezes and kills the cells)
Growths may also be treated with medications that cause the skin to peel or come off. More recently, lasers and other light sources have been used to treat actinic keratoses.
Creams such as 5-fluorouracil and imiquimod are used for people who have many lesions. These creams usually cause irritation and redness.
Expectations (prognosis)Actinic keratosis itself is benign (harmless), but it may on rare occasions develop into skin cancer.
Removal of the growth is usually effective.
Complications- Squamous cell carcinoma
- Irritation and discomfort of the skin growth
Call for an appointment with your health care provider if areas of persistent roughness or scaliness develop in sun-exposed skin.
PreventionReduce sun exposure and protect your skin from the sun:
- Wear protective clothing such as hats, long-sleeved shirts, long skirts, or pants.
- Try to avoid sun exposure during midday, when ultraviolet light is most intense.
- Use high-quality sunscreens, preferably with SPF (sun protection factor) rating of at least 15. Pick a sunscreen that blocks both UVA and UVB light.
- Apply sunscreen before going out into the sun, and reapply frequently.
- Use sunscreen year-round, including in the winter.
- Avoid sun lamps, tanning beds, and tanning salons.
Other important sun safety facts to keep in mind:
- Sun exposure is intensified in or near surfaces that reflect light, such as water, sand, concrete, and areas painted white.
- Sun exposure is more intense at the beginning of the summer.
- Skin burns faster at higher altitudes.

Pre-cancerous skin lesions, actinic keratosis, should be treated by a doctor. Options include freezing or burning it off, or the application of topical creams that will cause it to fall off. Follow up visits to check for recurrence are a good idea.

Although there is no cure for actinic keratosis per say, there are a couple treatment options that can effectively minimize the symptoms:
- Cryosurgery - uses liquid nitrogen to freeze off the lesions. It is fast, has a high cure rate, and is well-tolerated by most people. There may be a very high brief period of stinging when the liquid nitrogen is first applied, but anesthesia is not required.
- Shave removal - a procedure during which a scalpel is used to remove the lesion and obtain a specimen for testing.
- Curettage - often used to remove hard, thickened actinic keratoses. In this procedure, a small, round, sharp instrument (called a curette) is used to scrape the actinic keratosis, either removing a piece of it for biopsy or removing the entire lesion.
- Lasers - deliver an intense light focused on the lesion, removing it along with the top layer of skin. The finely controlled nature of laser removal makes this a useful option for actinic keratoses on delicate skin, such as the lips (actinic chelitis), or in narrow, hard-to-reach places (such as behind the ears).
- Photodynamic therapy - involves an agent applied to the skin that makes the skin sensitive to light (usually applied by injection or topically). An intense light is then point in the area and the laser light destroys the damaged skin cells.
- Retinoids - is an oral drug (isotretinoin) is very effective in treating actinic keratosis. However it is only recommended in high risk cases because it has significantly high risk side effects.
- Creams and Ointments - destroy actinic keratosis cells by blocking essential reactions within them. Creams can be used as an actinic keratosis natural therapy for they support the skin's immune system and stimulate the body's own natural rejection of these precancerous cells.

Actintic Keratoses are dry, scaly patches that form on sun exposed areas of the skin, including the scalp, face, forearms, and back of the hands.
Actinic keratoses are usually scaly, feel like sandpaper to the touch, and range in color from skin-toned to reddish-brown. Actinic keratosis may be as small as the head of a pin or as large as a quarter (or bigger, if left untreated).

Actinic Keratosis (AK) is known as a UV-light induced lesion of the skin that may develop into invasive squamous cell carcinoma. It is by far the most common lesion with malignant potential to arise on the skin. The lesion is a scaly or crusty bump that forms on the skin surface, also called solar keratosis, sun spots, or precancerious spots. They range in size from as small as a pinhead to over an inch in diameter. They may be light or dark, tan, pink, red, a compination of these, or the same color as the skin. Most likey, keratoses appear on consistently exposed skin areas such as face, ears, bald scalp, neck, backs of hands and forearms, and lips. The lesion may be flat or raised in appearance.

Actinic keratosis are precancerous lesions on the skin that has been chronically exposed to the sun. Being precancerous, or premalignant, A.K. can develop into skin cancer. However, relatively few of them actually develop into cancers, a process that takes years for the most part. When a premalignant lesion becomes malignant the cancer is called a squamous cell carinoma. Although squamous cell skin cancers have the potential for metastasis (spreading to other areas), such cancers that arise in preexisting actinic keratoses have a low potential for such spread, and only do so once they have gone deeper and the skin and become invasive. If treated correctly at the early stage, this chances of this occurring are reduced.

No, Actinic Keratosis is not contagious. It is a patch of skin on an area exposed to sun for many years (such as the back of the hands or forearms) which may turn into cancer. Treatment is available for this condition.

I just had a lichenoid keratosis removed by a plastic surgeon. My dematologist said it looked like a squamous cell carcinoma, which I have had on the same leg. For that reason alone, I had it removed. It came back as benign, however, I have been reading that a lichenoid keratosis is like a pre-cancerous actinic keratosis, which can turn into cancer. I am happy it is gone.
