皮膚癌（Skin cancer）預防的核心在於減少紫外線（UV）輻射暴露。紫外線是皮膚 DNA 受損的主因，SPF（Sun Protection Factor）30 可阻擋約 97% 的 UVB。除了防曬乳，護理師應教導「ABCDE」原則自我檢查皮膚病灶，並強調在上午 10 點至下午 4 點間減少曝曬，穿著防護衣物與戴帽的重要性。
Using broad-spectrum sunscreen with an SPF of at least 30 is critical because it blocks approximately 97% of UVB rays, which are a primary cause of skin DNA damage and cancer. Sunscreen should be used daily regardless of cloud cover, as UV radiation penetrates clouds, and clients should also be advised to limit exposure during peak hours and wear protective clothing.
