USPSTF releases updated recommendations on skin cancer screening
Skin cancer is the most commonly diagnosed cancer in the United States, but there are different types that vary in their incidence and severity. Basal and squamous cell carcinomas are the most common types of skin cancer, but they infrequently lead to death or substantial morbidity, notes the USPTSF. Melanomas represent about 1% of skin cancer and cause the most skin cancer deaths. An estimated 8000 individuals in the United States will die of melanoma in 2023.
Thus, differences in anatomical distribution of skin cancers in in the various subpopulations needs to be considered when performing skin screening, they write."Furthermore, while skin cancer risk is lower among people with darker skin pigmentation, survival is often worse for cancers like melanoma, highlighting the potential need for screening."
Foundational evidence showed that the sensitivity of visual skin examination by a clinician to detect melanoma ranged from 40% to 70% and specificity ranged from 86% to 98%. Evidence that evaluated the diagnostic accuracy of visual skin examination to detect keratinocyte carcinoma was limited and inconsistent. There were no new studies reporting on diagnostic accuracy for an asymptomatic screening population.
