Pathophysiology Of Esophageal Cancer

Esophageal cancer is a tumor that begins to grow in the lining of the esophagus, and then can grow through the wall of the esophagus. If the tumor grows through the esophageal wall, it can spread to diametrical parts of the body through the lymphatic system. The areas at the hindquarters of the esophagus, and where the esophagus joins the stomach, are lined with columnar cells. If a malignant tumor grows here, its called adenocarcinoma which is what my pt has. Studies have shown a shackle between frequency of reflux symptoms and risk of adenocarcinoma. The constant venomous reflux will irritate the lining of the esophagus, and complications can occur, such as Barretts esophagus (a condition that occurs because of continued reflux of drift from the stomach into the lower esophagus.) The reflux eventually changes the cells at the terminus of the esophagus. Esophageal tumors begin as benign growths and grow quick because there is no serosal layer to stop growth. Beca use of the vast lymphatic network of the esophagus, esophageal cancers spread fast, both locally to regional lymph nodes and distantly to the lungs and liver.

Complications include pulmonary problems that result from fistulae and aspiration, including pneumonia and pulmonary abscess; impaction of the tumor into major vessels, causing a intensityive bleed; thwarter and compression of the other structures in the head and make knocked out(p); weight loss and nutritional deficiencies due to bar swallowing; lubricious food impaction can result when there is awfully stenosis, requiring endoscopic intervention for disimpaction; regur gitation of food or free-spoken secretions! may also occur; or the tumor smoke may cause compression and obstruction of the tracheobronchial tree, leading to dyspnea( bar breathing), inveterate cough, and at times post obstructive pneumonia. The most roughhewn symptom of esophageal cancer, leading to its diagnosis is progressive dysphagia, difficulty or inability to swallow solid foods (eventually liquids also)....If you want to trace a full essay, order it on our website: BestEssayCheap.com
