Researchers published a plasma protein profiling study that detects cancer in patients presenting with non‑specific symptoms, reporting a minimally invasive screening approach with high sensitivity. The team validated a protein signature capable of flagging malignancy across multiple tumor types, proposing the panel as a triage tool in primary care to prioritize diagnostic workups. The study provides test performance metrics and discusses integration into clinical pathways to reduce diagnostic delay. For readers: plasma protein profiling measures circulating biomarkers to infer disease states without tissue sampling.
