Utah Esthetician State Board Practice Exam

What is the most prevalent type of skin cancer?

1. Melanoma

2. Squamous cell carcinoma

3. Basal cell carcinoma

4. Keratoacanthoma

The correct answer is: Basal cell carcinoma

Basal cell carcinoma is recognized as the most prevalent type of skin cancer, accounting for the majority of skin cancer diagnoses. This type arises from the basal cells, which are located in the lowest layer of the epidermis. It is primarily associated with prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds, leading to the abnormal growth of skin cells. What sets basal cell carcinoma apart is not only its frequency but also its behavior; it tends to grow slowly and usually does not metastasize (spread to other parts of the body), which makes it less dangerous than other types of skin cancer, such as melanoma. However, if left untreated, it can invade local tissues and cause significant damage. Understanding the prevalence and characteristics of basal cell carcinoma is crucial for estheticians, as early detection and intervention are essential for managing skin health and guiding clients on proper sun protection measures.
