The IARC convened a working group of experts in Lyon, France, on 10-18 April, 2000, to evaluate the cancer-preventive activity of sunscreens and to compile the fifth volume of the IARC Handbooks of Cancer Prevention. The working group concluded that the topical use of sunscreens reduces the risk of sunburn in humans and that sunscreens probably prevent squamous-cell carcinoma of the skin when used mainly during unintentional sun exposure. No conclusion can be drawn about the cancer-preventive activity of topical use of sunscreens against basal-cell carcinoma and cutaneous melanoma. Use of sunscreens can extend the duration of intentional sun exposure, such as sunbathing. Such an extension may increase the risk for cutaneous melanoma. The working group warned against relying solely on sunscreens for protection from UV radiation.
2000年4月10日至18日，国际癌症研究机构（IARC）在法国里昂召集了一个专家工作组，以评估防晒霜的防癌活性，并编撰《IARC癌症预防手册》第五卷。工作组得出结论，局部使用防晒霜可降低人类晒伤风险，且主要在无意暴露于阳光下时使用防晒霜可能预防皮肤鳞状细胞癌。关于局部使用防晒霜预防基底细胞癌和皮肤黑色素瘤的防癌活性，尚无定论。使用防晒霜可延长有意暴露于阳光下的时间，如日光浴。这种延长可能会增加患皮肤黑色素瘤的风险。工作组警告不要仅依赖防晒霜来防护紫外线辐射。
