Which statement is true of basal cell carcinoma?

Basal cell carcinoma (BCC) is indeed known as the most common type of skin cancer. It arises from the basal cells, which are located in the outer layer of the skin. While it is classified as the least severe form of skin cancer, it can still pose significant health risks if left untreated, particularly due to its potential to invade nearby tissues. BCC typically occurs in areas of the skin that are frequently exposed to sunlight, such as the face, neck, and arms, which is why its prevalence is often noted in sun-exposed regions. Although it is generally slow-growing and rarely metastasizes (spreads to other parts of the body), early detection and treatment are crucial to prevent more serious complications or extensive damage to surrounding tissues.

The other statements are inaccurate for various reasons. BCC does not appear exclusively on the face; it can develop on any body part exposed to UV radiation. It also does not usually resolve without treatment, as these tumors typically require medical intervention to properly address them. Furthermore, while individuals with fair skin are at a higher risk, BCC can also occur in people of all skin tones, making it misleading to suggest it is found primarily in those with darker skin.
