Early-Onset Gastrointestinal Cancer Rates Rise in Young Adults in Latin America

Medical experts in the United States and Colombia report a growing number of gastrointestinal (GI) cancers diagnosed in patients younger than 50. Dr. Christina Wu of Mayo Clinic notes that colorectal cancer remains the most common early-onset GI cancer worldwide, followed by stomach, esophageal and pancreatic cancers, with rarer cases involving the bile ducts, gallbladder, appendix, neuroendocrine tumors and small intestine.

Both articles cite genetic conditions such as Lynch syndrome and familial adenomatous polyposis, chronic inflammatory diseases and lifestyle factors—including sedentary habits, obesity, high consumption of processed foods, alcohol and tobacco—as contributors to the trend. Clinicians recommend earlier screening: US guidelines suggest beginning colon cancer screening at age 45 for average‑risk adults, with earlier tests for those having risk factors. In Colombia, specialists at a regional oncology symposium advocate endoscopy and colonoscopy from age 45 for asymptomatic individuals and stress rapid assessment of any alarm symptoms. Advanced imaging such as PET scans is highlighted as improving tumor localization and treatment planning.
