Final answer:
Actinic keratosis can develop into basal cell carcinoma if not treated. This cancer arises from stem cells in the epidermis and is linked to sun exposure and UV radiation. Early detection and protection from UV rays are crucial for prevention and effective treatment.
Step-by-step explanation:
If actinic keratosis (sun-exposed areas) is not treated, it can potentially develop into basal cell carcinoma. Basal cell carcinoma is a type of skin cancer that arises in the mitotically active stem cells in the stratum basale of the epidermis. It's crucial to recognize that extended exposure to UV radiation and other risk factors like radiation exposure and wounds on the skin can increase the risk of this cancer. Basal cell carcinomas are most commonly found on body areas with long-term sun exposure such as the head, neck, arms, and back.
Being vigilant about any changes in your skin and seeking medical advice early can lead to more effective treatments for basal cell carcinomas, such as surgery, cryosurgery, or topical ointments. Adequate protection against UV radiation, including the use of sunscreen with a high SPF, wearing protective clothing, and avoiding peak sunlight hours, is vital for prevention.
