Precancerous conditions of the skin are changes to the skin cells that make them more likely to develop into cancer. Actinic keratosis is not yet cancer. But if it isn’t treated, it may develop into a type of non-melanoma skin cancer called squamous cell carcinoma. Actinic keratosis is also called solar keratosis.
How serious is precancerous skin cells?
Some actinic keratoses can turn into squamous cell skin cancer. Because of this, the lesions are often called precancer. They are not life-threatening. But if they are found and treated early, they do not have the chance to develop into skin cancer.
How is precancerous skin cancer treated?
Cryotherapy is used most often for pre-cancerous conditions such as actinic keratosis and for small basal cell and squamous cell carcinomas. For this treatment, the doctor applies liquid nitrogen to the tumor to freeze and kill the cells.
What does pre cancer skin look like?
AKs often appear as small dry, scaly or crusty patches of skin. They may be red, light or dark tan, white, pink, flesh-toned or a combination of colors and are sometimes raised. Because of their rough texture, actinic keratoses are often easier to feel than see.
What does a precancerous skin biopsy mean?
If your dermatologist tells you that you have a precancerous skin growth, it means one thing. Your skin has been badly damaged by the sun, indoor tanning, or both. The good news is that it’s not too late to do something about this damage and protect your health.
What causes precancerous?
The most common cause of precancerous skin is damage to the DNA inside skin cells. Damage to DNA can cause changes in various genes that usually control cell growth, prolong cell survival, manage cell division, and prevent unwanted cell death.
Can you scratch off actinic keratosis?
While an actinic keratosis can sometimes resolve on its own, it usually recurs after further sun exposure; if scratched or picked off, it will return as well.
Can a biopsy remove skin cancer?
If the doctor thinks that a suspicious area might be skin cancer, the area (or part of it) will be removed and sent to a lab to be looked at under a microscope. This is called a skin biopsy. If the biopsy removes the entire tumor, it’s often enough to cure basal and squamous cell skin cancers without further treatment.
What are the main warning signs of skin cancer?
Redness or new swelling beyond the border of a mole. Color that spreads from the border of a spot into surrounding skin. Itching, pain, or tenderness in an area that doesn’t go away or goes away then comes back. Changes in the surface of a mole: oozing, scaliness, bleeding, or the appearance of a lump or bump.
Does everyone have precancerous cells?
No, we don’t all have cancer cells in our bodies. Our bodies are constantly producing new cells, some of which have the potential to become cancerous. At any given moment, we may be producing cells that have damaged DNA, but that doesn’t mean they’re destined to become cancer.
What does Stage 1 melanoma look like?
Stage I melanoma is no more than 1.0 millimeter thick (about the size of a sharpened pencil point), with or without an ulceration (broken skin). There is no evidence that Stage I melanoma has spread to the lymph tissues, lymph nodes, or body organs.
What are brown crusty spots on skin?
A seborrheic keratosis (seb-o-REE-ik ker-uh-TOE-sis) is a common noncancerous skin growth. People tend to get more of them as they get older. Seborrheic keratoses are usually brown, black or light tan. The growths look waxy, scaly and slightly raised.
Are skin cancers itchy?
Skin cancers often don’t cause bothersome symptoms until they have grown quite large. Then they may itch, bleed, or even hurt. But typically they can be seen or felt long before they reach this point.
How often does actinic keratosis become cancerous?
Only about 10 percent of actinic keratoses will eventually become cancerous, but the majority of SCCs do begin as AKs. Unfortunately, there’s no way to tell which AKs will become dangerous, so monitoring and treating any that crop up is the only way to be sure.
Can precancerous cells disappear?
Abnormal or precancerous cells often go away on their own (becoming normal cells again) without treatment. Since it is impossible to predict whether treatment is needed or not, the Pap smear test screens for abnormal and precancerous cells on the cervix.
How long does actinic keratosis take to heal?
How long does it take for actinic keratosis to go away? Depending on the size and number of actinic keratoses (AKs), it can take up to three months for AKs to disappear after treatment ends. After the AKs go away, you will need to see your healthcare provider for a checkup once or twice a year.
