When cancer hides its origins: unique insights from Barrett's esophagus and esophageal adenocarcinoma
Barrett's esophagus, specifically the intestinal metaplasia that defines it at a cellular level, is the universal precursor to esophageal adenocarcinoma.
This matters significantly for how we approach cancer early detection, because current screening guidelines focus on patients with a visible, measurable Barrett's segment. The true precursor may be smaller, shorter, or confined to microscopic changes that escape standard endoscopy. Protein markers like REG4 and Trefoil Factors could offer a minimally invasive way to identify people at risk before cancer develops.
