Feels like food keeps getting stuck in my throat but had n endoscopy done and it came back with mucus. would a tumour have been detected in this test?

Dysphagia: Difficulty swallowing typically comes from throat swelling and could be a sign of a food-allergy related disease called eosinophilic esophagitis (eoe). This problem is growing in frequency but requires a biopsy for diagnosis. Speak to a gastroenterologist about this problem, if the scope was done by a GI dr., let them know your symptoms are continuing to help them find alternative explainations.
