Which of the following is a protective factor for skin cancer?

Regular check-ups and self-exams for moles are crucial protective factors for skin cancer because they help in early detection of changes in the skin that may indicate cancer. By regularly monitoring moles or new skin changes, individuals can identify warning signs such as asymmetry, irregular borders, or color variations. Early detection significantly increases the chances of successful treatment and better outcomes.

In contrast, high exposure to sunlight is a known risk factor for skin cancer, as UV radiation can damage skin cells and lead to cancerous growths. While smoking cessation and obesity management are beneficial for overall health and the prevention of various diseases, they are not directly linked as protective factors specifically for skin cancer. Thus, the emphasis on regular skin checks underscores the importance of proactive measures in skin cancer prevention and early intervention.
