Mohs Surgery for Basal Cell Carcinoma: A Systematic Review

Abstract

Keratinocyte carcinomas (KCs) are, by far, the most common malignancies worldwide and exceed the prevalence of all other cancers combined. Traditionally, approximately 80% of KC cases have been attributed to basal cell carcinoma (BCC) and 20% to squamous cell carcinoma (SCC). However, recent studies point to an increasing SCC incidence relative to BCC, moving the historical 4:1 ratio to 2.5:1 or even closer. [1]
