Objective: The incidence of melanoma has increased dramatically over the past four decades, while overall mortality has remained stable. This increase in incidence without a change in overall mortality may be due to overdiagnosis through skin cancer screening. Despite the USPSTF citing insufficient evidence for or against professional skin cancer screening in average-risk adults, U.S. skin cancer screening practices may be leading to overdiagnosis of skin cancers. Methods: Two reviewers examined the online recommendations for skin cancer screening of 1113 U.S. cancer centers accredited by the Commission on Cancer, including 66 designated by the National Cancer Institute (NCI). Recommendations on skin cancer screening, such as age, frequency, and patient population (i.e. high-risk of developing skin cancer, “people of color”) were documented. Results: We found that 18% of centers (202) recommended professional screening in average-risk adults, 35.8% (399) advised regular self-examination, and only 3.4% (38) cited insufficient evidence for screening practices; 49% of NCI centers (32/66) recommended screening in high-risk adults compared to 13% of non-NCI centers (135/1047; p = 0.0004); 0.45% of centers (5) mentioned the potential harms of screening, while 3.5% (39) specifically recommended screening for people of color. Conclusion: Our study reveals that many U.S. cancer centers advise some form of skin cancer screening despite a lack of evidence for or against these practices. Few centers mentioned the potential harms of screening, including overdiagnosis. This indicates a need for stronger evidence for specific screening guidelines and for greater public awareness of the potential benefits and harms of routine skin cancer screening. © The Author(s) 2024. |
