Actinic keratosis is a common skin disorder that is caused by sun exposure. It is characterized by rough, scaly patches of skin that may be red, pink, or brown in color. These patches can develop anywhere on the body, but they are most commonly found on the face, ears, neck, scalp, arms, and hands. Although actinic keratosis is not cancerous, it can become cancerous if left untreated.
The exact rate of actinic keratosis becoming cancerous is not known, but estimates range from 2 to 10 percent. That means that for every 100 actinic keratoses, two to ten of them will become malignant. The risk of cancer is highest when the lesions are thick, have an irregular border, and have an ulcerated surface. It is also higher in people with a history of skin cancer.
Actinic keratosis can be treated in different ways, depending on the severity of the condition. Treatments range from topical creams and ointments to cryotherapy and laser therapy. Treatment can help reduce the risk of the lesions becoming cancerous.
In conclusion, actinic keratosis can become cancerous, although the exact rate is not known. The risk of cancer is highest when the lesions are thick, have an irregular border, and have an ulcerated surface. Treatment can help reduce the risk of cancer, so it is important to consult a doctor if you suspect that you may have actinic keratosis.
