A Proposal to Improve the Early Diagnosis of Symptomatic Cancers in the United States

Abstract

Many people are diagnosed with cancer after presenting with signs and symptoms of their disease to a healthcare provider. Research from developed countries suggests that, in addition to indicating later-stage disease, symptoms can also indicate earlier-stage disease, leading to investment in research and quality improvement efforts in the early detection of symptomatic cancers. This approach, labeled early diagnosis of symptomatic cancers, focuses on identifying cancer at the earliest possible stage in patients with potential signs and symptoms of cancer, and subsequently diagnosing and treating the cancer without delay. In the United States, early detection has focused on cancer screening, with relatively less research focused on early diagnosis of symptomatic cancers. In this commentary, we propose that research focused on early diagnosis of symptomatic cancers provides an important opportunity to achieve more earlier-stage cancer diagnoses in the United States. We highlight the potential of these efforts to improve cancer outcomes, and outline a research agenda to improve early diagnosis of symptomatic cancers in the United States focused on defining and describing pathways to cancer diagnosis, identifying signs and symptoms that can be used to promote early cancer detection, and developing interventions to improve early diagnosis of symptomatic cancers.
