Photocarcinoma, which includes basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma, provides a considerable challenge to doctors. Early detection is critical for improving outcomes for people diagnosed with photocarcinoma. This chapter discusses the procedures and techniques used to detect basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma in their earliest stages, when treatment is most effective. We give a thorough explanation of self-skin examination procedures, allowing people to monitor their own skin for worrisome changes. The chapter also discusses the importance of professional skin examinations by dermatologists and other healthcare providers, including the use of dermoscopy to improve diagnosis accuracy. We address the clinical features of early-stage photocarcinoma, emphasizing the necessity of detecting subtle signs and symptoms that may go unnoticed. Finally, we look at the changing landscape of early detection technologies, such as artificial intelligence and teledermatology, and how they can increase access to screening and reduce diagnostic delays.
