AI Article Synopsis
- The debate surrounding overdiagnosis and overtreatment in breast screening mammography is ongoing, with some cancers detected possibly being harmless and never symptomatic in a patient's lifetime.
- The focus is on low-grade ductal carcinoma in situ (DCIS), which may constitute a significant portion of such cases, and we examine its natural history and prognosis.
- The article also discusses the complexity of low-risk DCIS beyond just low cytonuclear grade and evaluates the differences between active surveillance and surgical excision, including ongoing clinical trials on this topic.
Article Abstract
The issue of overdiagnosis and overtreatment of lesions detected by breast screening mammography has been debated in both international media and the scientific literature. A proportion of cancers detected by breast screening would never have presented symptomatically or caused harm during the patient's lifetime. The most likely (but not the only) entity which may represent those overdiagnosed and overtreated is low-grade ductal carcinoma in situ (DCIS). In this article, we address what is understood regarding the natural history of DCIS and the diagnosis and prognosis of low-grade DCIS. However, low cytonuclear grade disease may not be the totality of DCIS that can be considered of low clinical risk and we outline the issues regarding active surveillance vs excision of low-risk DCIS and the clinical trials exploring this approach.
