Esophageal cancer is often detected too late because early-stage esophageal tumors usually cause no noticeable symptoms. Many patients ignore mild signs such as occasional difficulty swallowing, acid reflux, or chest discomfort, mistaking them for common digestive problems. As the disease progresses, symptoms become more severe, leading to delayed diagnosis. Lack of routine screening also contributes to late detection. According to Dr. Dodul Mondal, the Best Oncologist in Delhi, early medical evaluation of persistent swallowing difficulties can help identify an esophageal tumor before it reaches an advanced stage.
